2 Safety instructions
2.1 General
Observe the operating instructions. Non-observance of the instructions, operation
which is not in accordance with use as prescribed below, wrong installation or
incorrect handling can affect the safety of operators and machinery.
The installation and connection must comply with the applicable national and
international standards. Responsibility lies with the person installing the device.
The device must only be installed, connected and put into operation by a qualified
electrician as the safe function of the device and machinery is only guaranteed
when installation is correctly carried out.
Disconnect the unit externally before handling it.
In case of malfunction of the device or uncertainties please contact the
manufacturer. Tampering with the device can seriously affect the safety of
operators and machinery. This is not permitted and leads to an exclusion of liability
and warranty.

2.2 Radio equipment
In general, radio equipment must not be used in the vicinity of petrol stations, fuel
depots, chemical plants or blasting operations.
►Do not transport and store any flammable gases, liquids or explosive
substances near the unit.
2.3 Interference of electronic and medical devices
Operation can affect the function of electronic devices that are not correctly
shielded.
►Disconnect the device in the vicinity of medical equipment.
►Contact the manufacturer of the corresponding device in case of any
interference.
3 Functions and features
In connection with the evaluation unit DTE10x the read/write head ANT512
enables non-contact reading and/or writing of the RFID transponders (ID-TAGs)
conforming to the system.The data is converted into digitally coded values and
provided to the evaluation unit.
4 Functions
4.1 Operating principle
The ID tags are operated passively, i.e. without battery. The energy required for
operation is supplied by the read/write head.The physical principle of the energy
transfer is based on inductive coupling. The integrated antenna coil in the read/
write head generates a magnetic field which partly penetrates the antenna coil of
the ID tag. A voltage is generated by induction that supplies the data carrier with
energy.

5 Installation
5.1 General installation instructions
When mounting several read/write heads adhere to the minimum distances
between the systems.
Flush mounting of a read/write head in metal reduces the read/write
distance.
The immediate vicinity of powerful HF emission sources such as welding
transformers or converters can affect operation of the read/write heads.
Information on the available mounting accessories is available on our website at:
www.ifm.com → data sheet search → ANT512 → Accessories
5.2 Notes on ID tag mounting
If the ID tags are mounted in/on metal, the read/write distance is reduced.
For positioning the ID tags the read/write heads are marked with an an-
tenna symbol on the active face. It designates the middle of the integrated
antenna coil and has to correspond with the middle of the ID tag.
The orientation of the read/write head antenna axis must correspond with
the axis of the ID tag coil.
You can find out about the best way to position the available ID tags and on
mounting in metal on our website:

5.3 Avoiding interference
The device generates a modulated electrical field with a frequency of 125 kHz.
To avoid interference of the data communication no other devices generating
interference emission in this frequency band must be operated in its vicinity. Such
devices are for example frequency converters and switched-mode power supplies.
5.4 Mechanical design
On delivery the sensing face is facing the front.
