    DTM424 DTM425 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.

  • Page 6: Intended Use

    DTM424 DTM425 3 Intended use The read/write head reads and writes ID tags without contact. The data is made available as process data via the CAN-bus interface.

  • Page 7: Items Supplied

    DTM424 DTM425 4 Items supplied • Read/write head • 2x hexagonal nut The device is supplied without installation and connection accessories. Available accessories: www.ifm.com. The optimum function is not ensured when using components from other manufacturers.

  • Page 8: Function

    DTM424 DTM425 5 Function 5.1 ID tags 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.

  • Page 9: Installation

    DTM424 DTM425 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.
