3 Product description
3.1 Setup and function
The safety switch consists of two components:
•Sensor
The sensor is mounted on the fixed part of the protective device.
•Actuator (transponder)
The actuator is mounted on the moving part of the protective device.
When the protective device is closed, the actuator is guided to the sensor. When the
switch on distance is reached, the sensor detects the actuator code. If the sensor
detects a taught-in code (valid actuator), it sets safety outputs OSSD 1 and OSSD 2
(semiconductor outputs) to High and application diagnostic output Aux to Low.
When the protective device is opened, the actuator is removed from the response range
of the sensor. The sensor sets safety outputs OSSD 1 and OSSD 2 to Low and applica‐
tion diagnostic output Aux to High.
3.2 Product characteristics
3.2.1 Product variants
The safety switch is delivered in different variants. You will find an overview of impor‐
tant distinguishing features of the variants in the following.
•Universally coded, unique coded, and permanently coded safety switches
•Actuator design: “Standard”, “Flat”, or “Mini”
•Cable with M12 plug connector (5-pin or 8-pin) or flying leads (3 m or 10 m)
Complete overview of all variants: see "STR1 ordering information", page 40.
Coding
•Universally coded
All actuators are accepted. No teach-in is required.
•Unique coded
An actuator must be taught in during commissioning. Up to 8 actuators may be
taught in one after the other. Only the most recently taught-in actuator is valid.
Previously taught-in actuators can no longer be used.
•Permanently coded
An actuator must be taught in during commissioning. Teach-in only needs to be
performed once. It is not possible to teach in any further actuators.
3.2.2 Active sensor surfaces
The sensor has 3 active sensor surfaces:
•Front: black surface
•2 x sides: yellow surface with long black edge
3.2.3 Fault detection
Faults that arise, including internal device faults, are detected no later than the next
requirement to close the safety contacts (e.g., when the machine starts). The safety
switch then switches to the safe state. If a fault is detected, the safety circuit is
switched off and the DIAG and STATE light emitting diodes display the fault (see
table 10).

4.1 Manufacturer of the machine
DANGER
Failure to comply with manufacturer’s obligations
Hazard due to lack of effectiveness of the protective device
bPerform a risk assessment before using the safety switch.
bDo not manipulate, open, or modify components of the safety switch.
bDo not repair defective devices; replace them instead.
bMake sure the switch-on commands that cause the machine to enter a dangerous
state only take effect when the protective device is closed.
bMake sure a stop command is triggered when the protective device is opened in a
hazardous machine state.
bSafety switches must not be bypassed (i.e., the contacts jumpered), swiveled out
of the way, removed, or rendered ineffective in any other way. If necessary, take
measures to reduce the possibility of bypassing.
If multiple devices are connected in series (cascaded) and the simplified procedure
according to ISO 13849 is used to determine the performance level (PL), the PL may
drop.
As the number of safety switches in a cascade increases, so too does the response
time.
4.2 Operating entity of the machine
DANGER
Failure to comply with operating entity’s obligations
Hazard due to lack of effectiveness of the protective device
bModifications to the machine and modifications to the mechanical mounting of
the safety switch necessitate a new risk assessment. The results of this risk
assessment may require the operating entity of the machine to fulfill the manufac‐
turer’s obligations.
bApart from during the procedures described in this document, the components of
the safety switch must not be opened or modified.
bDo not perform repair work on the components. Improper repair of the safety
switch can lead to a loss of the protective function.
bMake sure that bypassing is not carried out by substitute actuators. Restrict
access to actuators for unlocking.

4.3 Design
DANGER
Bypassing the protective device
Hazard due to lack of effectiveness of the protective device
bPrevent incentives to manipulate the safety switch by taking at least one of the fol‐
lowing measures:
Universally coded variant only:
°Cover the sensor and the actuator with additional equipment or protect them
against access.
°If possible, use non-detachable mounting methods for actuators (such as
welding, gluing, safety screws, or rivets).
Mounting location
bWhen the protective device is closed, the sensor and actuator must face each
other at the safe switch on distance of Sao or closer (see table 3).
bSelect a mounting location that allows the sensor and actuator to be accessed for
maintenance work and protects them against damage.
bIf possible, mount the sensor and actuator on non-ferrous subsurfaces and at a
distance from metallic parts in order to avoid affecting the sensing range. If this is
not possible, the effect on the safe switch on distance Sao and the safe switch off
distance Sar must be checked.
bMake sure that there is no possibility of hazards arising when the protective device
is opened, even if the actuator has not yet reached the safe switch off distance
Sar.
bIf the actuator is approaching the sensor in a parallel position, observe the mini‐
mum distances (see table 3).
bIf necessary, attach an additional stop for the moving protective device.
Distance
If multiple safety switches are mounted on the machine, they must be mounted with a
minimum distance in relation to one another; see "Mounting", page 20.
Alignment
The sensor can be mounted in any alignment see "Mounting", page 20, see "Possible
mounting types", page 18.
Actuating direction
The actuator may approach the front or the long side of the sensor.
NOTE
If the actuator does not move directly onto the sensor when the protective device is
closed, but instead approaches it in a parallel position, the specified minimum distance
must be adhered to. This prevents the sensor from enabling the safety outputs despite
the protective device not being fully closed.
4.4 Integration into the electrical control
Switch-on commands that cause the machine to enter a dangerous state may only take
effect when the protective device is closed. In cases where the machine is in a danger‐
ous state, a stop command must be triggered if the protective device opens. Depending
on the safety concept, the signal is analyzed by, e.g., safety relays or a safety controller.

4.4.1 OSSDs
Safety switches with local inputs and outputs can be directly integrated into the
machine controller.
DANGER
Hazard due to lack of effectiveness of the protective device
In the case of non-compliance, it is possible that the dangerous state of the machine
may not be stopped or not stopped in a timely manner.
bMake sure that the following control and electrical requirements are met so the
protective function can be fulfilled.
•The output signals from an OSSD pair must not be connected to each other.
•In the machine controller, both signals from an OSSD pair must be processed sep‐
arately.
Figure 1: Dual-channel and isolated connection of OSSD 1 and OSSD 2
•The machine must switch to the safe state at any time if at least one OSSD in an
OSSD pair switches to the OFF state.
•Prevent the formation of a potential difference between the load and the protec‐
tive device. If you connect loads to the OSSDs (safety outputs) that then also
switch if controlled with negative voltage (e.g., electro-mechanical contactor with‐
out reverse polarity protection diode), you must connect the 0 V connections of
these loads and those of the corresponding protective device individually and
directly to the same 0 V terminal strip. In the event of a fault, this is the only way to
ensure that there can be no potential difference between the 0 V connections of
the loads and those of the corresponding protective device.
Figure 2: No potential difference between load and protective device

DANGER
Hazard due to lack of effectiveness of the protective device
In the case of non-compliance, it is possible that the dangerous state of the machine
may not be stopped or not stopped in a timely manner.
Downstream contactors must be positively guided and monitored depending on appli‐
cable national regulations or required reliability of the safety function.
bMake sure that downstream contactors are monitored (external device monitoring,
EDM).
Requirements for the electrical control of the machine
•Use the control without test pulses. The safety switch is self-testing.
•The safety switch tests the OSSDs at regular intervals. To do this, it switches each
OSSD briefly (for max. 1 ms) to the OFF state and checks whether this channel is
voltage-free during this time.
Make sure that the machine’s control does not react to these test pulses and the
machine does not switch off.
•The inputs of a connected evaluation unit must be positive-switching (PNP), as the
two outputs of the safety switch send a level of the supply voltage in the switched-
on state.
The OSSDs are short-circuit protected to 24 V DC and 0 V. When the actuator is in the
sensor’s response range, the OSSDs signal the ON state with the HIGH signal level
(non-isolated). If the actuator is removed from the sensor’s response range or there is a
device fault, the OSSDs signal the OFF state with the LOW signal level.
The safety switch complies with the regulations for electromagnetic compatibility (EMC)
for the industrial sector (Radio Safety Class A). Radio interference cannot be ruled out
when used in residential areas.
DANGER
Hazard due to lack of effectiveness of the protective device
In the case of non-compliance, it is possible that the dangerous state of the machine
may not be stopped or not stopped in a timely manner.
bMake sure that the following control and electrical requirements are met so the
safety switch can fulfill its protective function.
•The external voltage supply of the safety switch must be capable of buffering brief
power failures of 20 ms as specified in IEC 60204-1.
•The power supply unit must provide safe isolation according to IEC 61140 (SELV/
PELV). Suitable power supply units are available as accessories from SICK.
4.4.2 Application diagnostic output
The application diagnostic output signal changes as soon as the actuator is moved into
or leaves the response range of the safety switch. In other words, it does so when the
moving protective device is opened and closed. This is not a safety output.

Safety switch
Safe evaluation unit
It is not possible to use more than 30 safety switches in a cascade.
The maximum number of safety switches depends on the following factors:
•Applied supply voltage
•Length of cables used
•Cross-section of cables used
The voltage drop in the cascade must be checked to ensure that the defined minimum
voltage is still present at the last safety switch.
In the case of connection cables with a length of 2 m and a cable cross-section of
0.25 mm², the maximum number of cascadable safety switches is relative to the volt‐
age, as explained below:

Table 2: Maximum number of cascadable safety switches relative to the voltage
The number of safety switches in a cascade affects the response time of the system
(see "Response time and enable time in cascade", page 39).
The cascade can be created using special T-pieces and an end connector (see "Con‐
necting a cascade", page 25).
NOTE
In the case of safety switches cascaded using T-connectors, it is not possible to evalu‐
ate the application diagnostic output.

4.5 Thorough check concept
Thorough checks must be performed on the safety switch by appropriately qualified
safety personnel during commissioning, after modifications, and at regular intervals.
see "Thorough check", page 29
Regular thorough checks serve to investigate the effectiveness of the safety switch and
discover defects resulting from modifications or external influences (such as damage or
manipulation).
The manufacturer and operating entity must define the type and frequency of the thor‐
ough checks on the machine on the basis of the application conditions and the risk
assessment. The process of defining the thorough checks must be documented in a
traceable manner.
4.5.1 Minimum requirements for regular thorough checks
The following thorough checks must be carried out at least once a year:
•Thorough check of the principal protective function of the safety switch
•Thorough check of the safe sensing range Sar
•Thorough check for damage on the switch housing
•Thorough check for damage on the switch cables
•Thorough check for signs of misuse or manipulation on the safety switch

NOTE
If the actuator does not move directly onto the sensor when the protective device is
closed, but instead approaches it in a parallel position, the specified minimum distance
must be adhered to. This prevents the sensor from enabling the safety outputs despite
the protective device not being fully closed.
5.4 Mounting
Selecting the mounting location
If the machine documentation does not specify the mounting location, select one care‐
fully:
bWhen the protective device is closed, the sensor and actuator must face each
other at the safe switch on distance of Sao or closer (see table 3).
bSelect a mounting location that allows the sensor and actuator to be accessed for
maintenance work and protects them against damage.
bIf possible, mount the sensor and actuator on non-ferrous subsurfaces and at a
distance from metallic parts in order to avoid affecting the sensing range. If this is
not possible, the effect on the safe switch on distance Sao and the safe switch off
distance Sar must be checked.
bMake sure that there is no possibility of hazards arising when the protective device
is opened, even if the actuator has not yet reached the safe switch off distance
Sar.
bIf the actuator is approaching the sensor in a parallel position, observe the mini‐
mum distances (see table 3).
bIf necessary, attach an additional stop for the moving protective device.
Mounting the sensor
1. Mount the sensor on the fixed part of the protective device.
2. Take account of the tightening torque for the fixing screws: 1 Nm
Mounting the actuator
1. Align the actuator using the marking notches on the sensor.
Figure 4: Aligning the actuator on the sensor
2. If you are mounting using fixing screws, take account of the tightening torque for
the screws:

Hazard due to electrical voltage
Hazard due to unexpected starting of the machine
bMake sure that the machine is and remains disconnected from the power supply
during the electrical installation.
bMake sure that the dangerous state of the machine is and remains switched off
during electrical installation.
bMake sure that the outputs of the safety switch have no effect on the machine
during electrical installation.
DANGER
Incorrect safety switch connection
Loss of safety function
bWhen using insulation material or stranded connection wires, make sure they
demonstrate the required temperature resistance and mechanical load capability.
bUse only safe contacts for safety functions.
bUse a suitable voltage supply. Voltage must be supplied in accordance with SELV/
PELV (IEC 60204-1) for all devices that are electrically connected to the safety
switch.
bAll devices that are electrically connected to the safety switch must have the same
voltage supply.
bUse protected cable routing to eliminate cross-circuits and short-circuits.
bPower devices (such as motors) that represent a strong source of interference
must be kept isolated from circuits for signal processing. Route the cables for the
safety circuits as far away as possible from the power circuit cables.
bMake sure that 1 A fuse protection is provided for safety switches.
bMake sure that all electrical outputs have an adequate suppressor to accommo‐
date inductive loads. For this purpose, the outputs must be protected with an
appropriate suppressor such as a freewheeling diode, a varistor, or an RC element.
DANGER
Hazard due to lack of effectiveness of the protective device
The dangerous state may not be stopped in the event of non-compliance.
bOperate safety switches within the specifications. If you operate them outside the
specifications, this may result in the sensor temperature increasing and in a loss
of the safety function.
bMake sure that a current of no more than 100 mA is flowing at safety outputs
OSSD 1 and OSSD 2. Otherwise, it is no longer possible to guarantee the safety
function.

bPrevent the formation of a potential difference between the load and the protec‐
tive device.
bIf you connect loads to the OSSDs (safety outputs) that then also switch if control‐
led with negative voltage (e.g., electro-mechanical contactor without reverse polar‐
ity protection diode), you must connect the 0 V connections of these loads and
those of the corresponding protective device individually and directly to the same
0 V terminal strip. In the event of a fault, this is the only way to ensure that there
can be no potential difference between the 0 V connections of the loads and
those of the corresponding protective device.

7 Commissioning
7.1 Safety
DANGER
Hazard due to lack of effectiveness of the protective device
In the case of non-compliance, it is possible that the dangerous state of the machine
may not be stopped or not stopped in a timely manner.
1. Have qualified safety personnel perform a thorough check on the machine and
approve it before commissioning.
2. Make sure that the time for the safety requirement (closing the protective device
again) is longer than the risk time.
7.2 Switching on
The device initializes after switching on. During this process, the OSSDs are switched
off and the light emitting diodes light up alternately in the color sequence green, red,
and yellow. For unique coded and permanently coded safety switches only: If any actua‐
tors have already been taught in, the STATE light emitting diode will flash once after ini‐
tialization for each taught-in actuator.
7.3 Teach-in
DANGER
Bypassing the protective device
The dangerous state may not be stopped in the event of non-compliance.
bIf an actuator is taught in, document this
bDuring regular thorough checks, make sure that the taught-in actuator is still being
used.
Variant for universally coded actuators
No teach-in is required.
Variant for unique coded actuators
An actuator must be taught in during commissioning. Up to 8 actuators may be taught
in one after the other. Only the most recently taught-in actuator is valid. Previously
taught-in actuators cannot be taught in again.
Variant for permanently coded actuators
An actuator must be taught in during commissioning. It is not possible to teach in any
further actuators.
Teaching in an actuator
1. Open the physical guard.
2. Connect the safety switch to the voltage supply (see "Electrical installation",
page 22).
✓The start sequence is performed. The LEDs light up alternately in the color
sequence green, red, and yellow.
3. Close the physical guard.
✓When the guard is closed and the actuator has reached the appropriate position,
the safety switch will automatically start the teach-in sequence. The LEDs will dis‐

4. Within 5 minutes of successfully teaching in the actuator, connect and restore the
voltage supply for the safety switch.
✓Once the taught-in actuator is in the response range, both OSSDs switch to the ON
state and the STATE light emitting diode lights up green.
NOTE
Actuators can only be taught in at cascaded safety switches if voltage is present at
inputs In 1 and In 2. For this purpose, the actuators must be taught in individually in a
specific order. Viewed from the evaluation unit, teach-in starts at the last safety switch
in the cascade (STATE light emitting diode lights up red, DIAG light emitting diode is off).
Then the actuator is taught in at the second-to-last safety switch in the cascade, and so
on.
7.4 Thorough check
Requirements for the thorough check during commissioning and in certain situations
The protective device and its application must be thoroughly checked in the following
situations:
•Before commissioning
•After changes to the configuration or the safety function
•After changes to the mounting, the alignment, or the electrical connection
•After exceptional events, such as after a manipulation has been detected, after
modification of the machine, or after replacing components
The thorough check ensures the following:
•Compliance with all relevant regulations and effectiveness of the protective device
for all of the machine’s operating modes.
•The documentation corresponds to the state of the machine, including the protec‐
tive device
The thorough checks must be carried out by qualified safety personnel or specially
qualified and authorized personnel and must be documented in a traceable manner.
1. Check whether the protective device of the machine is effective in all operating
modes in which the machine can be set.
2. Make sure that the operating personnel have been instructed in the function of
the protective device before starting work on the machine. The instruction is the
responsibility of the machine operator and must be carried out by qualified per‐
sonnel.
