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 ANT424/

ANT425 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

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

antenna 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�

The best way to position the available ID tags and on mounting in metal is

available on our website: www�ifm�com

5.3 Avoiding interference

The device generates a modulated electrical field with a frequency of 13�56 MHz�

To avoid interference of the data communication no other devices generating

interference emission in this frequency band must be operated in the vicinity� Such

devices are for example frequency converters and switched-mode power supplies�
