A number of new functions have been provided to ensure that you can use the Safety
Light Curtain without lowering productivity. This lets you boost the safety of applications
that previously did not lend themselves to the use of a Safety Light Curtain.
Note: The new functions on this page require the use of a setting tool. For details, see page 63 Using Setting Tools.
Two new functions have been added to the muting function.
The muting function temporarily disables the Safety Light Curtain when an object must pass through the detection zone, such
as when supplying a workpiece to your equipment. "Partial muting," which further heightens the level of safety, and "position
detection muting," which allows muting when the safety status can be determined by the position of a machine (such as a
robot), have been newly added to the muting function.
Partial muting raises safety by muting only the beams of the Safety
Light Curtain in the area where the workpiece passes through,
while preventing muting in all other areas. The Safety Light Curtain
beams in all areas other than
where the workpiece passes
through are constantly
ON.
Only the beams of the Safety Light Curtain that
would be interrupted by the workpiece are muted.
● Position detection muting
This is used in applications where the workpiece is set in position each time by an
operator, and then a turntable or positioning robot moves the workpiece to the area
where the work is done. A limit switch or other means is used to detect when the
robot is in a safe position, and muting is then applied.
● Fixed blanking
The blanking function disables specific beams of the Safety Light Curtain.
When a part of a machine is located inside the detection zone of the Safety Light Curtain,
the safety output will normally remain OFF and the machine cannot operate. The blanking
function makes it possible to disable specific beams for applications such as this.
● Floating blanking
●
Dividing the zone between series-connected sensors
A warning zone can be set to alert people before they enter a danger zone.
For example, you can set the F3SJ to generate only an alarm when someone approaches the danger zone, and to turn OFF
the control output when someone actually enters the danger zone. You can also divide the detection zone for a single F3SJ
into two zones, or set a warning zone for multiple, series-connected F3SJ Units. Plus, the auxiliary output can be used to
activate a flashing lamp as a warning to alert the person before turning OFF the machinery.
●
A single sensor can also be divided
The beam that would otherwise be
constantly interrupted by the
workbench is disabled.
In this case, 2-beam floating
blanking is set. If three or more
beams are interrupted, the
output goes OFF.

sensor that fits your setup perfectly. Refer to the list of
sensor models on pages 13 and 15 to select the minimum
sensor length required to cover the area you want to protect.
Note: We can also manufacture sensors with lengths not included in the list
of models. For details, please consult your OMRON sales
representative.
Select the output transistor.
Choose the PNP type when installing in safety system
configurations that comply with the Machinery Directive or
when using with a dedicated controller (F3SP-B1P or F3SX).
NPN types are also available as standard products when

Select the application.
In addition to finger protection, hand protection, and
hand/arm protection models, new models have been added
that detects a leg or the presence of a person.
For areas where there is only a short distance to the source
of danger, select a finger protection model. For areas
where there is some distance to the hazardous point and
where the machinery stops with sufficient time to spare,
choose an economical hand/arm/body protection model.
Note: After selecting the type of device, calculate the safety distance
described on page 60 and change your selection if necessary.

The thin sensor saves valuable space.
The sensor is 6 mm thinner than our previous models. When
you include the newly designed mounting brackets, which
also enable beams to be aligned after the sensor is mounted,
the total thickness is 26 mm - a reduction of 19 mm compared
to previous models. The low profile means the sensor will not
get in the way when adding safety applications to existing
equipment.
Flexible cable with a 5 mm bending
radius makes wiring a snap.
The F3SJ cables (0.3 m) have M12 connectors and can be
routed in any direction. Problems with connector
compatibility have been eliminated.
The included standard mounting
brackets are easier than ever to use.
The included mounting brackets, which are suitable for
general use, have been redesigned with ease of use in mind.
The new design allows easy screwdriver access, even when
mounting in tight spaces.
Also, after aligning the beams, screws can be tightened
while oriented perpendicular to the lens surface, just like the
panel mounting screws. On previous models, the carefully
adjusted beam angles would sometimes come out of
alignment when tightening the final screws. This problem has
been solved with the F3SJ, because the screw-tightening
direction is different from the angle adjustment direction. The
result is reduced installation time.
Free-directional cables can be
routed down, back, left or right.
Flexible cables with 5 mm
bending radius can be
adhesively mounted to the
floor.
The sensor can be rotated along
its axis. Beam alignment can be
fine-tuned, even when mounted
side by side on a surface.
Side-mounting in tight spaces is simple.
When using standard mounting brackets to mount a sensor
on its side, the bracket protrudes outward in front of the lens
surface. When this protrusion is of concern, use the F39-LJ2
side-mounting brackets (sold separately).
Easy to change from previous models.
When replacing your previous standard multiple-beam area
sensor, use the F39-LJ4 top / bottom mounting bracket B
(sold separately), which features enlarged mounting holes.

Relays with Forcibly Guided Contacts
This configuration, which only OMRON can provide, features a sensor unit with
an output feedback function required for Safety Category 4. Simply by using a
pair G7SA or G7S-E Safety Relays, you can easily and economically configure
a Category 4 safety circuit.
The F3SJ-A Safety Light Curtain is a Type 4 safety sensor that can be used to configure a Category 4
safety circuit. Several suggested configurations that are ideal for a variety of safety needs are outlined
below.

Space-efficient and low-cost system
● Low-cost and
space-efficient
The built-in external device
monitoring function
eliminates the need for a
Safety Relay Unit. A welded contact
detection circuit can
be created using two
Safety Relays.
Using single Safety Relays requires a lot of labor for wiring. To simplify the connection process, use
F39-JC@B Double-end Connector Cable and an F3SP-B1P Dedicated Controller. (Use a PNP type
for this configuration. NPN types cannot be connected when using an F3SP-B1P Relay.)
Wire-saving configuration
● Reduced wiring and
easy maintenance
Cables with connectors on
both ends simplify
connection, and prevent
wiring errors.
When an emergency stop switch or door switch is used with the F3SJ-A Safety
Light Curtain, the safety circuit may become complex, making circuit design
difficult. For this, we recommend using the F3SX Safety Controller. Select the
model that best matches the required input combination. Use an F39-CN5
Branch Connector (sold separately) to significantly reduce the amount of labor
required for wiring to the terminal block.
Multi-input safety circuit configuration
OMRON has developed a unique interference light prevention algorithm that
automatically prevents malfunction, even when light is received from three sets.
This feature is ideal for applications
where it is not possible to perform wiring
with an interference sensor, such as
between an AGV and installed equipment.
Also, the Setting Tool can be used to
adjust the emitted light intensity to
minimize the effect of light on other
devices.
(Updated function)
Resistant to mutual interference. No wiring between
sensors and no interference for up to three sets.
Sensors with protective heights of up to nearly 2.5 meters are available for
applications that involve large-sized workpieces. And if you happen to make changes
in the future, you can always extend the protective height with series connections. Up
to four sets, or 400 beams, can be series-connected, and with series connection
cables up to 15 meters in length, applications can cover a wide area.
Maximum protective height of 2,500 mm.
Series connection is more convenient than ever.
To create "perfect fit" installations with no dead zones or extra space when
making series connections in L- or U-shaped configurations, use the F39-
LJ3 free-location mounting brackets (sold separately) and F39-JJR06L or
F39-JJR15L Side-by-side Series Connection Cable.

Built-in muting function
■ No controller required. Simply attach the Key Cap (sold separately) to
the sensor.
F39-CN6
Key Cap for Muting
The muting function temporarily disables the light curtain
when an object must pass through the detection zone, such
as when supplying a workpiece to your equipment.
In the past, this function required a dedicated muting
controller, but now it is built into the F3SJ. To use the muting
function, purchase the F39-CN6 Key Cap for Muting (sold
separately). The muting function is enabled simply by
replacing the Unit's cap with this Key Cap. In addition, a
muting sensor that determines the muting timing, as well as
a muting lamp that communicates the muting status to other
operators, should be connected to the F3SJ.

New functions for extra reliability.
Combine safety and productivity with a
controller-less muting function.
The incident light level indicator uses orange LED lights for
levels 1 to 3, and green LED lights for levels 4 to 5. The
green LED lights indicate that a stable amount of light is
being received. The error indicator uses a variety of
illumination and blinking patterns, enabling more detailed
diagnosis results to be communicated via the display.
A new and improved LED indicator.
The Safety Light Curtain can be disabled when
an AGV carrying a workpiece passes through.
The connectors for series connection feature an intelligent
design. To connect a series connection cable to the F3SJ,
remove the Key Cap that is required when the sensor is used by
itself. If you should happen to forget to connect the series
connection cable, the sensor will not operate by itself without the
Key Cap. This solves the problem of sensors operating
independently when a series connection cable is accidentally left
unconnected, such as when equipment is moved.
A measure to prevent you from forgetting
to connect a series connection cable.
Like previous Type 4 Safety Light Curtains, the F3SJ conforms to the latest
required safety standards and regulations. Since the F3SJ also complies with
IEC61508, the international standard for functional safety, safety is ensured
regardless of where it is used.
Complies with the latest international safety standards and regulations.
Operates as a single
sensor when the Key
Cap is attached.
Does not operate
without the Key Cap.
The quality of Safety Light Curtain performance is determined
by the quality of the emitter/receiver elements. With previous
models, one faulty beam resulted in the malfunction of the
entire sensor. However, the F3SJ features a newly developed
"1-bit module" that integrates the lens and other optical parts
with the emitter IC and receiver IC, which are key devices.
With characteristic inspection performed on each beam, as
well as a thorough quality traceability system using 2D codes,
performance is assured.
New core technology that supports reliability and customizability.

The newly developed board-free "1-

In addition to our standard products, we
are now able to manufacture devices with a

beam gaps. For details about these special
products, consult your OMRON sales representative.

Safety-related Functions
Interlock Function
The F3SJ turns the safety outputs OFF when the power is turned ON
or when a beam is interrupted, and maintains this state until a reset
signal is applied. This state is called "interlock".
You can reset this interlock by 2 methods; “auto reset that
automatically turns safety output ON when an interrupting object is
removed” and “manual reset mode that keeps safety output OFF until
a reset signal is provided if the interrupting object is removed”.
Auto Reset Mode
When an interrupting object is removed, safety output automatically
turns ON. Auto reset is used on machines where a worker is not able
to enter the area between the detection zone and the hazardous part
of the machine.
Note: Auto reset is always used in the F3SJ-A@-TS series.
Auto reset wiring procedure:
Manual Reset Mode
When a reset input is given while no interrupting object exists in a
detection zone, the safety outputs turn ON. This allows the machine
to be manually reset using a reset switch after ensuring safety,
preventing unexpected startup.
A sensor enters interlock state when:
•The power is turned ON (start interlock). This is useful if you want
to keep the machine stopped until start inspection is completed
after the power is turned ON.
•F3SJ is interrupted (restart interlock). After F3SJ is interrupted and
the machine stops, the machine can be restarted after safety is
ensured.
Manual Reset Wiring Procedure:
To reset:
Note: Install the reset switch outside the hazardous area, where the
operator can clearly see the hazardous area.
Interlock Function in a Muting System
Because the interlock selection input line is used as muting input 1
when using the muting function, the default setting is auto reset. Use
a setting tool for manual reset.
For PNP output For NPN output
1. Open the interlock selection
input line, or short-circuit it to 0
to 1.5 V (pin 1/white).
2. Short-circuit the reset input
line to 9 to 24 V (pin 4/yellow).
3. Turn ON the power of F3SJ.
1. Open the interlock selection
input line, or short-circuit it to 9
to 24 V (pin 1/white).
2. Short-circuit the reset input
line to 0 to 1.5 V (pin 4/yellow).
3. Turn ON the power of F3SJ.

Safety Light Curtain (Type 4) F3SJ Ver. 2 35
■Diagnostic Functions
Self-test
A self-test is performed to check for errors when the power is turned
ON (within 2 seconds / within 2.2 seconds when series connected).
Also, the self-test is regularly performed (within the response time)
while operating.
Waveform of Control Outputs
When the F3SJ is receiving light, the control outputs cyclically turn
OFF as shown below to test the output circuit. When this OFF signal
is fed back, the output circuit is diagnosed as normal. If the output
signal does not include an OFF pulse signal, the receiver determines
that a failure has occurred with the output circuit or wiring, and enters
lockout state. (Refer to the following illustration.)
External Test
This function performs a test to ensure that the safety system stops
properly when the F3SJ is interrupted, by using an external signal to
forcibly stop emission.
To stop emission, apply 9 to 24 V for PNP output types or 0 to 1.5 V
for NPN output types to the test input line of the emitter. Apply the
voltage for a minimum of 4 x the safety output response time.
Lockout
If an error is found in the self-test, the sensor enters lockout state,
keeps the safety output in the OFF state, and indicates the error at
the same time.
Resetting Lockout
When a cause of lockout is removed, you can release the lockout by
using either of the following methods.
•Cycle the power back ON
•Reset input
[For PNP output]
After manual reset, apply voltage of 9 to 24 V for 100 ms or longer to
the reset input line, and set it open or apply 0 to 1.5 V.
After auto reset, apply voltage of 0 to 1.5 V for 100 ms or longer to
the reset input line, and set it open or apply 9 to 24 V.
[For NPN output]
After manual reset, apply voltage of 0 to 1.5 V for 100 ms or longer to
the reset input line, and set it open or apply 9 to 24 V.
After auto reset, apply voltage of 9 to 24 V for 100 ms or longer to the
reset input line, and set it open or apply 0 to 1.5 V.
External Device Monitoring Function
This function detects malfunctions, such as welded contacts in
external relays (or contactors) that control the hazardous area of a
machine.
This function constantly monitors that a specified voltage is applied
to the receiver's external device monitoring input line, and enters
lockout state when an error occurs. The relay's operational delay can
be up to 300 ms without being evaluated as an error.
For example, if a specified voltage is not applied to the external
device monitoring line because the normally closed (NC) contact is
not closed within 300 ms after the control outputs turn from ON to
OFF, it is evaluated as an error and enters a lockout state.
To utilize this function properly, use safety relays and contactors that
have forcibly guided or mechanically linked contact structure.
Other Functions
Auxiliary Output (Non-safety output)
The auxiliary output is used to monitor the status of the F3SJ.
This output can be connected to a device such as a relay, indication
lamp, programmable controller, etc.
There are two auxiliary outputs: Auxiliary output 1 and auxiliary
output 2.
•Auxiliary output 1: Control output inversion signal
•Auxiliary output 2: Turns ON when the point of 30,000 operating
hours is reached
The auxiliary output modes can be changed with a setting tool. See
the User's Manual for details on the modes that can be set.
!WARNING
Do not use the auxiliary output or external indicator output for safety
applications.
Failure of these outputs may prevent detection of people and result in
serious injury.
Note: 1. Auxiliary output 1 has a load current of 300 mA max., and
auxiliary output 2 has a load current of 50 mA.
2. The timing when auxiliary output 1 is set as a control output
inversion signal is shown in the diagram below.
Toff: Response time of control output's ON to OFF, Ton: Response
time of control output's OFF to ON
Note: When auxiliary output 2 is set as a control output inversion
signal, the response delay for control output becomes Toff x 3
max.

48 Safety Light Curtain (Type 4) F3SJ Ver. 2
System Configuration and Connection (Muting system)
Muting System
The muting function temporarily disables the safety function of the
F3SJ, keeping the control outputs ON even if beams are interrupted.
This makes it possible to install safety light curtains for AGV
passage, enabling both safety and productivity.
When muting, the muting lamp (external indicator) blinks to notify
people in the surrounding area that the safety functions are disabled.
!WARNING
The muting and override functions disable the safety functions of the
device. Additional safety measures must be taken to ensure safety
while these functions are working.
Install muting sensors so that they can distinguish between the
object that is being allowed to be pass through the detection zone
and a person.
If the muting function is activated by the detection of a person, it may
result in serious injury.
Muting lamps (external indicators) that indicate the state of the
muting and override functions must be installed where they are
clearly visible to workers from all the operating positions.
Upgrading F3SJ for Muting System
1. Remove the caps of the emitter and receiver.
(A screwdriver is included with the key cap for muting.)
2. Install a muting lamp (external indicator) on either the emitter or
receiver.
3. Attach the key cap for muting to the emitter/receiver on which the
muting lamp (external indicator) was not installed.
Muting Sensor
The muting sensor is the sensor that is the trigger for temporarily
disabling the safety functions of F3SJ. You can use a photoelectric
switch of through-beam or retro-reflective types, proximity sensor, or
limit switch. (OMRON's E3Z series, E2E series, and D4N series
sensors are recommended.) For the PNP type F3SJ, use a sensor
with PNP transistor outputs or N.O type contacts. For the NPN type
F3SJ, use a sensor with NPN transistor outputs or N.O type
contacts. For NPN type F3SJ, use a sensor with NPN transistor
outputs or N.O type contacts.
Muting Lamp (External indicator)
To notify workers that the muting function is working, external lamp(s)
must be installed. Use the F39-A01P@-PAC external indicator set or
an F39-JJ3N universal indicator cable with a commercially available
external indicator.
F3SJ Internal Indicators
•The muting input 1 indicator turns ON when input is applied to
muting input 1.
•The muting input 2 indicator turns ON when input is applied to
muting input 2.
•The muting input 1 indicator and muting input 2 indicator blink
under muting override.
•The muting error indicator on the receiver side turns ON when
there is a muting error.
Attachment Positions for Included Labels
Internal indicator labels are included with the F39-CN6 Key Cap for
Muting. When using a muting system, attach the internal indicator
labels so the arrows will be in line with the positions of the indicators,
as shown by the shading below.

Standard Muting Mode
The F3SJ is set to this operation mode when it is shipped from the
factory. The muting function is enabled by providing a time lag
between muting inputs 1 and 2. Use a separately purchased setting
tool to change parameters related to muting time, or to select other
muting operation modes.
Start Conditions
If both of the following 2 conditions are present, muting is activated.
1. No interrupting object is found in the F3SJ's detection zone, and
control output is ON.
2. After muting input 1 is turned ON (connected to 9 to 24 V for PNP
types, or to 0 to 1.5 V for NPN types), muting input 2 is turned ON
(connected to 9 to 24 V for PNP types, or to 0 to 1.5 V for NPN
types) within the muting input time limit T1 min. to T1 max. (0.03
to 3 s).
Once the conditions in item 2 above are met, the muting function will
be enabled in 0.15 s max.
When condition 1 is satisfied but time condition of 2 is not, a muting
sequence error occurs and receiver’s muting error indicator turns
ON.
However, the F3SJ safety functions will continue operating and the
F3SJ will operate normally even during a muting error.
A muting error is released when either of the following occurs:
•When muting is started using a proper procedure
•When power is turned on while muting inputs 1 and 2 are OFF
End Conditions
If either of the following conditions are satisfied, the muting state is
released.
1. Muting input 1 or 2 turns OFF for T3 (0.1 s) or longer.
2. When the muting continuation time exceeds the muting time limit
of T2 (60 s) (a setting tool can be used to change the limit in the
range of 1 to 600 s, or to eliminate the time limit)
∗: This value is the time when the F3SJ is used singly. When used in
a series, this time is as shown in the table below.
•T1 min: Muting input time limit (min.)
This is the minimum input time lag between muting inputs 1 and 2,
and is set to 0.03 s. If the time lag between muting inputs 1 and 2
are shorter than this value, a muting error is generated.
•T1 max: Muting input time limit (max.)
This is the maximum input time lag between muting inputs 1 and 2,
and is set to 3 s. The minimum value must be less than the
maximum value (min. < max.).
•T2: Muting time limit
This is the continuous time of the muting function, and is set to
60 s. If the muting status exceeds this time, muting is cancelled.
•T3: Allowable pulse-change time for muting input signals
This is the maximum time allowed for a change in the waveform
pulse of muting inputs 1 and 2 while in the muting status.
Note: The muting status can be released even when the system
enters lockout.
The following values can be changed using the Setting Support
Software for the F3SJ:
•T1 min: Muting input time limit (min.)
•T1 max: Muting input time limit (max.)
•T2: Muting time limit
The following values can be changed using the Setting Console:
•T2: Muting time limit
Installation Standard for Muting Sensors
•Set the muting sensors so that they can detect all of the passing
detection objects (palettes, automobiles, etc.). Do not install in a
position so that only the front or rear end of the detection object is
detected.
•Set the muting sensors so that they detect the objects even when
they are loaded on palettes or other transport devices.
•Install the F3SJ and muting sensors so that each object passes
through all muting sensors before the next object arrives at the first
muting sensor. Also, install all F3SJ and muting sensors so that no
person is able to accidentally enter the hazardous area while the
muting function is enabled.
•When objects pass through the muting area at different speeds,
consider limiting the muting time.
•For a muting sensor installation example, see the instruction
manual.
•For details about the override function, see the instruction manual.

Warning Labels
For users
!WARNING
The FS3J must be installed, set, and integrated into the mechanical
control system by a qualified technician who has received the
appropriate training. Failure to make correct settings may prevent
detection of people and result in serious injury.
When changing parameters with a setting tool (F39-GWUM or F39-
MC21), the change must be made and the contents of the change
must be managed by the person in charge of the system.
Unintentional or mistaken parameter changes may prevent detection
of people and result in serious injury.
For machines
!WARNING
Do not use this sensor for machines that cannot possibly be stopped
by electrical control. For example, do not use it for a pressing machine
that uses full-rotation clutch. Otherwise, the machine may not stop
before a person reaches the hazardous part, resulting in serious
injury.
Do not use the auxiliary output or external indicator output for safety
applications. Failure of the F3SJ may cause a person to go
undetected, resulting in serious injury.
Prohibited
Indicates a prohibited action.
58 Safety Light Curtain (Type 4) F3SJ Ver. 2
For mounting
!WARNING
Make sure to test the operation of the F3SJ after installation to verify
that the F3SJ operates as intended. Do not operate the machine until
the test has been completed and F3SJ operation has been verified.
Unintended function settings may cause a person to go undetected,
resulting in serious injury.
Make sure to secure the safety distance between the F3SJ and the
hazardous parts. Otherwise, the machine may not stop before a
person reaches the hazardous part, resulting in serious injury.
Install a protective structure so that the hazardous part of a machine
can only be reached by passing through the sensor's detection zone.
Install the sensors so that part of the person is always present in the
detection zone when working in a machine's hazardous areas. If a
person is able to step into the hazardous area of a machine and
remain behind the F3SJ's detection zone, configure the system with
an interlock function that prevents the machine from being restarted.
Otherwise it may result in heavy injury.
Install the interlock reset switch in a location that provides a clear view
of the entire hazardous area and where it cannot be activated from
within the hazardous area.
The F3SJ cannot protect a person from an object flying from a
hazardous area. Install protective cover(s) or fence(s).
When detection of an area has been disabled by the fixed blanking
function, provide a protective structure around the entire area that will
prevent a person from passing through it and reaching the hazardous
part of the machinery. Failure to do so may prevent detection of
people and result in serious injury.
After setting the fixed blanking function, be sure to confirm that a test
rod is detected within all areas that require detection. Failure to do so
may prevent detection of people and result in serious injury.
When the fixed blanking function or the floating blanking function is
used, the diameter for the smallest detectable object becomes larger.
Be sure to use the diameter for the smallest detectable object for the
fixed blanking function or the floating blanking function when
calculating the safety distance. Failure to do so may prevent the
machinery from stopping before a person reaches the hazardous part
of the machinery, and result in serious injury.
The muting and override functions disable the safety functions of the
device. Additional safety measures must be taken to ensure safety
while these functions are working.
Install muting sensors so that they can distinguish between the object
that is being allowed to be pass through the detection zone and a
person. If the muting function is activated by the detection of a person,
it may result in serious injury.
Muting lamps (external indicators) that indicate the state of the muting
and override functions must be installed where they are clearly visible
to workers from all the operating positions.
Muting times must be precisely set according to the application by
qualified personnel who have received appropriate training. In
particular, if the muting time limit is to be set to infinity, the person who
makes the setting must bear responsibility.
Use two independent input devices for the muting inputs.
Install the F3SJ, Muting Sensors, or a protective wall so that workers
cannot enter hazardous areas while muting is in effect, and set muting
times.
Position the switch that is used to activate the override function in a
location where the entire hazardous area can be seen, and where the
switch cannot be operated from inside the hazardous area. Make sure
that nobody is in the hazardous area before activating the override
function.
Install the sensor system so that it is not affected by reflective
surfaces. Failure to do so may hinder detection, resulting in serious
injury.
When using more than 1 set of F3SJ, install them so that mutual
interference does not occur, such as by configuring series
connections or using physical barriers between adjacent sets.
Make sure that the F3SJ is securely mounted and its cables and
connectors are properly connected.
Make sure that no foreign material, such as water, oil or dust, enters
the inside of the F3SJ while the cap is removed.
Do not use the sensor system with mirrors in as retro-reflective
configuration. Doing so may hinder detection. It is possible to use
mirrors to "bend" the detection zone to a 90-degree angle.
When using series connections, perform inspection of all connected
F3SJs as instructed in the User's Manual.
For wiring
!WARNING
For PNP output, connect the load between the output and 0 V line.
For NPN output, connect the load between the output and +24 V line.
Connecting the load between the +24 V and 0 V lines results in a
dangerous condition because the operation mode is reversed to "ON
when light is interrupted".
[For PNP output]
Do not short-circuit an output line to +24 V line. Otherwise, the output
is always ON, creating a dangerous situation. Also, 0 V of the power
supply must be grounded so that output should not turn ON due to
grounding of the output line.
[For NPN output]
Do not short-circuit an output line to 0 V line. Otherwise, the output is
always ON, creating a dangerous situation. Also, the +24 V line of the
power supply must be grounded so that output does not turn ON due
to grounding of the output line.

Configure the system by using the optimal number of control outputs
that satisfy the requirements of the necessary safety category.
Do not connect each line of F3SJ to a DC power supply higher than
24 V+20%. Also, do not connect to an AC power supply.
Failure to do so may result in electric shock.
For F3SJ to comply with IEC 61496-1 and UL 508, the DC power
supply unit must satisfy all of the following conditions:
• Must be within rated power voltage (24 VDC±20%).
• Must have tolerance against the total rated current of devices if it is
connected to multiple devices.
• Must comply with EMC directives (industrial environment)
• Double or enhanced insulation must be applied between the primary
and secondary circuits.
• Automatic recovery of overcurrent protection characteristics
(reversed L sagging)
• Output holding time must be 20 ms or longer.
• Must satisfy output characteristic requirements for class 2 circuit or
limited voltage current circuit defined by UL508.
• Must comply with EMC, laws, and regulations of a country or a
region where F3SJ is used. (Ex: In EU, the power supply must
comply with EMC Low Voltage Directive.)
Double or enhanced insulation from hazardous voltage must be
applied to all input and output lines. Failure to do so may result in
electric shock.
The cable extension length must be no greater than the specified
length. Otherwise, the safety functions may fail to work properly,
resulting in danger.
Others
!WARNING
To use the F3SJ in PSDI mode (restart of cycle operation by the
sensor), you must configure an appropriate circuit between the F3SJ
and the machine. For details about PSDI, refer to OSHA1910.217,
IEC61496-1, and other relevant standards and regulations.
Do not try to disassemble, repair, or modify this product. Doing so may
cause the safety functions to stop working properly.
Do not use the F3SJ in environments where flammable or explosive
gases are present. Doing so may result in explosion.
Perform daily and 6-month inspections for the F3SJ. Otherwise, the
system may fail to work properly, resulting in serious injury.

60 Safety Light Curtain (Type 4) F3SJ Ver. 2
Safety Distance
The safety distance is the distance that must be set between the
F3SJ and a machine's hazardous part to stop the hazardous part
before a person or object reaches it. The safety distance varies
according to the standards of each country and the individual
specifications of each machine. In addition, the calculation of the
safety distance differs if the direction of approach is not
perpendicular to the detection zone of the F3SJ. Always refer to
relevant standards.
!WARNING
Make sure to secure the safety distance (S) between the F3SJ and
the hazardous part. Otherwise, the machine may not stop before a
person reaches the hazardous part, resulting in serious injury.
Note: The response time of a machine is the time period from when
the machine receives a stop signal to when the machine's
hazardous part stops.
Measure the response time on the actual system. Also,
periodically check that the response time of the machine has
not changed.
How to calculate the safety distance specified by International
standard ISO13855-2002 (European standard EN999-1999)
(reference)
If a person approaches the detection zone of the F3SJ
perpendicularly, calculate the safety distance as shown below.
S = K x T + C . . . Eq. (1)
•S: Safety distance
•K: Approach speed to the detection zone
•T: Total response time of the machine and F3SJ
•C: Additional distance calculated by the detection capability of the
F3SJ
System that has detection capability of 40 mm max.
Use K = 2,000 mm/s and C = 8 x (d - 14 mm) in equation (1) for the
calculation.
S = 2,000 mm/s x (Tm + Ts) + 8 x (d - 14 mm)
•S = Safety distance (mm)
•Tm = Machine's response time (s)
•Ts = Response time of the F3SJ from ON to OFF (s)
•d = Size of F3SJ‘s detection capability (mm)
[Calculation example]
When Tm = 0.05 s, Ts = 0.01 s, and d = 14 mm:
S = 2,000 mm/s x (0.05 s + 0.01 s) + 8 x (14 mm - 14 mm)
= 120 mm . . . Eq. (2)
If the result is less than 100 mm, use S = 100 mm.
If the result exceeds 500 mm, use the following equation
where K = 1,600 mm/s.
S = 1,600 mm/s x (Tm + Ts) + 8 x (d - 14 mm) . . . Eq. (3)
If the result of this Eq. (3) is less than 500 mm,
use S = 500 mm.
Systems with a Smallest Detectable Object Size (Diameter) Greater
than 40 mm
Assuming K = 1,600 mm/s and C = 850 mm, the following calculation
is made using Eq. (1).
S = 1,600 mm/s x (Tm + Ts) + 850 … Eq. 4,
•S = Safety distance (mm)
•Tm = Machine's response time (s)
•Ts = Response time of the F3SJ from ON to OFF (s)
Calculation example:
When Tm = 0.05 s and Ts = 0.01 s,
S = 1,600 mm/s x (0.05 s + 0.01 s) + 850 mm = 946 mm
How to calculate the safety distance specified by American
standard ANSI B11.19
(Ref.)
If a person approaches the detection zone of the F3SJ
perpendicularly, calculate the safety distance as shown below.
S = K x (Ts + Tc + Tr + Tbm) + Dpf
•S: Safety distance
•K: Approach speed to the detection zone (the value recommended
by OSHA standard is 1,600 mm/s)
Approach speed K is not specified in the ANSI B.11.19 standard. To
determine the value of K to apply, consider all factors, including the
operator's physical ability.
•Ts = Machine's stop time (s)
•Tr = Response time of the F3SJ from ON to OFF (s)
•Tc = Machine control circuit's maximum response time required to
activate its brake (s)
•Tbm = Additional time (s)
If a machine has a brake monitor, "Tbm = Brake monitor setting time
- (Ts + Tc)". If it has no brake monitor, we recommend using 20% or
more of (Ts + Tc) as additional time.
•Dpf = Additional distance
According to ANSI's formula, Dpf is calculated as shown below:
Dpf = 3.4 x (d - 7.0): Where d is the detection capability of the F3SJ
(unit: mm)
[Calculation example]
When K = 1,600 mm/s, Ts + Tc = 0.06 s, brake monitor setting time =
0.1 s, Tr = 0.01 s, d = 14 mm:
Tbm = 0.1 - 0.06 = 0.04 s
Dpf = 3.4 x (14 - 7.0) = 23.8 mm
S = 1,600 x (0.06 + 0.01 + 0.04) + 23.8 = 199.8 mm

Distance from Glossy Surface
!WARNING
Install the sensor system so that it is not affected by reflection from a
glossy surface. Failure to do so may hinder detection, resulting in
serious injury.
Install the sensor system at distance D or further from highly
reflective surfaces such as metallic walls, floors, ceilings, or
workpieces, as shown below.
Prevention of Mutual Interference
Mutual interference from other F3SJ is prevented in up to 3 sets
without series connection.
For series connection
Series connections can prevent mutual interference when multiple
sensors are used. Up to 4 sets, 400 beams, can be connected
(except for the F3SJ-A@-TS Series, for which up to 3 sets,
240 beams, can be connected). The emission of series-connected
F3SJ is time-divided, so mutual interference does not occur and
safety is ensured.
For no series connection
An interference light prevention algorithm prevents mutual
interference in up to 3 unconnected sets. If 4 or more sets of F3SJ
are installed and are not connected to each other, arrange them so
that mutual interference does not occur. If 2 sets are installed near
each other, reflection from the surface of the F3SJ may cause mutual
interference. When mutual interference occurs, the F3SJ enters
lockout. Combining countermeasures 1 to 3 below is effective.
1. Install a physical barrier

2. Alternate the direction of emission (alternation)
If sensors of 2 sets are installed too close to each other, mutual
interference may occur due to reflection by the surface.
This can be resolved by using a setting tool to shorten the detection
distance.

Applications Supported by the Setting Tools
Fixed Blanking Function
Summary
Disables specific F3SJ light beams.
!WARNING
When the fixed blanking function is used to disable detection in an
area, install blocking structures or shielding to prevent passage into
the entire hazardous area where detection has been disabled.
Failure to do so may prevent detection of people and result in serious
injury.
When an allowable range of light beams has been set for fixed
blanking, the size of the smallest detectable object will be larger in the
vicinity of interrupting objects. Calculate the safety distance to match
the settings.
After setting the fixed blanking function, you must verify that the F3SJ
detects a test rod at any position in the entire area where intrusion
must be detected. Failure to do so may prevent detection of people
and result in serious injury.
Example Application
In this example, there is always an object such as a conveyor belt in
the detection area, and we want to ignore the conveyor belt.
Description of Functions
Fixed Blanking Function
This function disables part of the F3SJ's detection area and
maintains the control output's ON status even if there is an object in
the disabled area.
The light beams set for fixed blanking must be one area of
consecutive light beams and up to five areas can be set (areas 1 to
5). Fixed blanking cannot be set for all of the light beams.
Setting the Fixed Blanking Area
Set the area that will be subject to fixed blanking.
An interrupting object can be placed in the detection area to perform
teaching and specify light beams for manual settings.
Note: 1. When the Setting Console is being used, only one area can
be set as a fixed blanking area.
2. When the SD Manager Setting Support Software is being
used, up to five areas can be set as fixed blanking areas.
Floating Blanking Function
Summary
Increases the diameter of the F3SJ's smallest detectable object and
turns OFF the control output when multiple objects are detected.
!WARNING
When the floating blanking function is used, it increases the diameter
of the F3SJ's smallest detectable object. Always use the larger
diameter when calculating the safety distance. If the incorrect
diameter is used in the calculation, the machinery may fail to stop
before an operator reaches the hazardous area, resulting in serious
injury.
After setting the floating blanking function, always verify that the F3SJ
system operates as expected. Serious injury may result if an
individual is not detected.
Example Application
When there is a moving object with a fixed width in the detection area
that we do not want to detect, the detection function can be disabled.
Description of Functions
Floating Blanking Function
This function increases the diameter of the smallest detectable
object to allow passage of objects of a certain size or allow
interrupting objects in multiple locations.
Setting the Floating Blanking Area
When the Setting Console is being used, all of the light beams are
set as the floating blanking area. When the SD Manager Setting
Support Software is being used, just one area can be set but the
range of the area can be specified. In the following example, the
floating blanking area is set from the 5th light beam to the 10th light
beam (counting from the bottom). An interrupting object can be
placed in the detection area to perform teaching and specify light
beams for manual settings.
Floating Light Beams
The following charts show the relationship between the number of
floating light beams and the safety output operation (safety output
not going OFF). Measure the size of the interrupting object
(maximum diameter) and set the number of floating light beams so
that the object's size is less than the corresponding dimension shown
in the chart.

Example Setting
When an F3SJ-A@14 is being used with an interrupting object that is
20 mm in diameter, set three light beams as floating light beams.
With this setting, the F3SJ's safety output will not turn OFF even if
there is an interrupting object up to 22-mm wide in the floating
blanking area.

Floating Blanking Mode
The floating blanking function has two operation modes.
1. Continuous Light Beam Mode
The safety output will not go OFF if the interrupting object is
smaller than the set size, although the safety output will go OFF if
objects pass through several areas in the detection area.
The floating blanking monitor function can be set in this mode.
Refer to the User's Manual for details.
2. Discontinuous Light Beam Mode
A light blockage is detected when the number of light beams
blocked in the area is equal to or greater than the preset number
of light beams.

Warning Zone Function
Summary
The detection zone can be divided into the detection zone and a
warning zone.
!WARNING
The warning zone output is not a safety output. Do not include this
area in the safety distance calculation. Shortening the safety distance
may result in serious injury.
The warning zone cannot be used for safety purposes. Always install
the system so that the hazard is reached by passing through the
detection zone.
The warning zone function can be
used only when the F3SJ is
installed horizontally. This function
cannot be used when the F3SJ is
installed vertically.
Example Application
When an individual enters, a warning lamp lights or buzzer sounds
without stopping the equipment.
Description of Function
Warning Zone Function
Use teaching to set the light beams that you want to set as the
warning zone or manually specify the light beams from the lowest or
highest beam. (See figures 1 and 2.)
To indicate that the warning zone is blocked, allocate the auxiliary
output or external indicator output as the warning zone information.
The following settings cannot be made:
•Setting all light beams as the warning zone (figure 4)
•Setting a warning zone that does not include one of the outer light
beams (figure 5)
If Safety Light Curtains are connected in series, and at least one of
an F3SJ's light beams is a normal light beam, all of a Light Curtain's
light beams can be set as a warning zone (figure 3).

Muting Function
Summary
Makes settings related to the muting function.
!WARNING
The muting function disables the safety functions of the device.
Additional safety measures must be taken to ensure safety while this
function is working.
Install muting sensors so that they can distinguish between the object
that is being allowed to be pass through the detection zone and a
person.
Muting lamps (external indicators) that indicate the status of the
muting function must be installed where they are clearly visible to
workers from all the operating positions.
Muting times must be precisely set according to the application by
qualified personnel who have received appropriate training. In
particular, if the muting time limit is to be set to infinity, the person who
makes the setting must bear responsibility.
Use two independent input devices for the muting inputs. (For the
PNP output-type F3SJ, use a sensor with a PNP transistor output or
N.O. contact. For the NPN output-type F3SJ, use a sensor with an
NPN transistor output or N.O. type contact.)
To prevent a worker from entering the hazardous area while the
muting function is engaged, install the F3SJ, muting sensor, and then
a protective barrier and set a limited muting time.
Example Applications
•Allowing only work pieces to pass into the conveyor entrance
•Operating the muting function in a specific area only
•Setting a different muting mode when standard muting is not
appropriate for the application
Description of Functions (See User's Manual for details.)
Operation Modes
When the SD Manager Setting Support Software is being used, any
one of the following three operation modes can be selected for the
muting function.
1. Standard Muting Mode
This is the default operation mode, which is set when the F3SJ is
shipped from the factory.
The muting function is enabled by turning ON muting inputs 1 and
2 with a time lag.
Note: Settings such as the muting time limit value can be changed.
2. Specialized Exit Muting Mode (Can be set with the SD Manager
Setting Support Software only.)
The muting function is enabled by turning ON muting inputs 1 and
2 with a time lag.
Installation of the muting input sensors is simpler than standard
mode because the Safety Light Curtain's blocked light status is
used to end muting.
3. Position Detection Muting Mode (Can be set with the SD Manager
Setting Support Software only.)
Sensors such as limit switches are used for the muting inputs and
the muting function is enabled by turning muting input from OFF
to ON and then turning muting input 2 from ON to OFF within time
difference T1 max. Use hybrid redundant inputs such as a
combination of an N.O. contact input and an N.C. contact input.
(When using a PNP-output photoelectric switch, use L/ON
operation on one side and D/ON operation on the other side.)
This mode is useful when you want to disable the F3SJ
temporarily, such as when a person is placing an object at the
conveyor entrance.
Partial Muting (Muting area) Settings
The light beams controlled by the muting function can be specified
with a setting tool. (When the F3SJ is shipped, all light beams are
set.)
The light beams can be specified by teaching/recording the blocked
light beams as muting light beams or manually specifying the desired
light beams.
Safety Light Curtain (Type 4) F3SJ Ver. 2 69
Indicator and I/O Settings
Auxiliary Output (Non-safety) and External Indicator Output (Non-safety)
Summary
A setting tool can be used to change the allocation of auxiliary
outputs 1 and 2, and external indicator outputs 1 and 2.
!WARNING
Do not use the auxiliary outputs or external indicator outputs for
safety purposes. Serious injury may result if an output fails and a
person is not detected.
Example Applications
•Allocating a lockout output or warning zone output to an auxiliary
output
•Connecting an external indicator to an auxiliary output and making
it flash
An auxiliary output or external indicator output can be connected to
an incandescent light to function as a broken-wire or short-circuit
detector. Refer to the User's Manual for details.
Output Operation Modes (when allocated to an auxiliary output or external indicator output)
Note: 1. A light blockage was detected even though the output is not turned OFF because the blockage occurred at a light beam subject to fixed
blanking, floating blanking, or muting. Blockages are also not processed during overrides.
2. The fixed blanking light beams or floating blanking light beams must be set.
3. The specified light beam must be set.
4. The warning zone light beams must be set.
5. When "specified light beam output" is allocated as the output operation mode for auxiliary output 1 or 2 or external indicator output 1 or
2, that mode cannot be allocated to the other output operations.

When replacing F3SN-@@@@P(N)14 with F3SJ-A@@@@P(N)14
For length greater than F3SN-@0234P(N)14:
Add 11 to the F3SN's 4-digit number and apply it as the F3SJ's 4-digit number, and then replace with the standard brackets included with the
product.
[Selection example] F3SN-A0315P(N)14 becomes F3SJ-A0326P(N)14 (replace with standard brackets)
Note: 1. The protective height becomes 11 mm longer.
2. Replace with outward-facing mounting of F39-LJ5 when you want to set the detection surface height to be same as the F3SN.
However, the F39-LJ5 and intermediate mounting brackets cannot be mounted simultaneously, so set the protective height to 600 mm or
less.
When replacing F3SN-@@@@P (N)25 with F3SJ-A@@@@P (N)20
For length greater than F3SN-@0262P(N)25:
Subtract 17 from the F3SN's 4-digit number and apply it as the F3SJ's 4-digit number, and then replace with the standard brackets included with
the product.
[Selection example] F3SN-A0322P(N)25 becomes F3SJ-A0305P(N)20 (replace with standard brackets)
Note: 1. The protective height gets 17 mm shorter.
2. Replace with outward-facing mounting of F39-LJ5 when you want to set the detection surface height to be same as the F3SN.
However, the F39-LJ5 and intermediate mounting brackets cannot be mounted simultaneously, so set the protective height to 600 mm or
less.
