2 Safety instructions
General
• The unit described is a subcomponent for integration into a system.
– The system architect is responsible for the safety of the system.
– The system architect undertakes to perform a risk assessment and to create documentation in
accordance with legal and normative requirements to be provided to the operator and user of
the system. This documentation must contain all necessary information and safety instructions
for the operator, the user and, if applicable, for any service personnel authorised by the
architect of the system.
• Read this document before setting up the product and keep it during the entire service life.
• The product must be suitable for the corresponding applications and environmental conditions
without any restrictions.
• Only use the product for its intended purpose (Ò → Intended use).
• If the operating instructions or the technical data are not adhered to, personal injury and/or damage
to property may occur.
• The manufacturer assumes no liability or warranty for any consequences caused by tampering with
the product or incorrect use by the operator.
• Installation, electrical connection, set-up, operation and maintenance of the product must be
carried out by qualified personnel authorised by the machine operator.
• Protect units and cables against damage.
Radio equipment
In general, radio equipment must not be used in the vicinity of petrol stations, fuel depots, chemical
plants or blasting operations.
uDo not transport and store any flammable gases, liquids or explosive substances near the unit.
Interference of electronic and medical devices
Operation can affect the function of electronic devices that are not correctly shielded.
uDisconnect the device in the vicinity of medical equipment.
uContact the manufacturer of the corresponding device in case of any interference.

5 Function
5.1 ID tags
The ID tags are passively operated without a battery. The energy required for operation is provided by
the read/write head.
The energy is provided via an 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.
The device supports ID tags according to ISO 15693.

6 Installation
6.1 Notes on the unit installation
When mounting several RFID units adhere to the minimum distances between the systems.
Flush mounting of a read/write head in metal reduces the read/write distance.
Device performance can be affected if positioned in the immediate vicinity of powerful HF
emission sources such as welding transformers or converters.
6.2 Avoiding interference
The device generates a modulated electrical field with a frequency of 13.56 MHz.
Avoid interference with data communication:
uDo not operate any devices in the vicinity that use the same frequency band.
wSuch devices are for example frequency converters and switched-mode power supplies.
If there are other devices in the same frequency band in the vicinity:
uThe mounting distances between the devices should be as large as possible.
uUse the devices in alternating operation.
uSwitch the HF field of the device on/off.

6.6 Positioning of the ID tags
The read/write heads are marked with an antenna symbol on the sensing face. It designates the
middle of the integrated antenna coil and has to correspond with the middle of the ID tag.
uAlign the axes of the RFID device and the ID tag in the same way.
For installation in or on metal use the ID tags provided for this purpose.
Position the ID tag in the area of the sensing face. When doing so, the angle of aperture and the
operating distance must be adhered to (→ Data sheet of the device).

Glossary
ID tag
An ID tag is used to identify objects. A read/
write device is used to read the ID tag via a
high-frequency radio signal. An ID tag
consists of an antenna, an analogue circuit
for receiving and transmitting (transceiver),
a digital circuit and a non-volatile memory.
