Transponder Antenna
HG G-98780
13,56 MHz | 1-dim. | seriell | CAN / Profibus®
The transponder antenna is used for the lo-calization and tracking of rail-mounted cranes with the aid of ground marks (transponders). The antenna described here is particularly suitable for vehicles outdoors, as the electronic units are encapsulated in the antenna housings. It operates on the frequency 13.56 MHz and thus has a large frequency separation from sources of interference such as drives, converters and switching power supplies. All important settings, adjustment work and software updates can be carried out via a serial interface.
When the antenna passes over a transponder, the transponder is supplied by an energy field of 13.56 MHz and transmits its code back to the antenna by modulating this frequency. The interpreter integrated in the antenna decodes the code. When the center of the antenna is crossed (at right angles to the direction of travel), a high-precision positioning pulse (PosiPuls) of adjustable duration is output. Furthermore, various characteristics of the antenna – such as current consumption and supply voltage etc. – are measured and added to the serial output protocol on request.
The serial signal is output as a potential-separated RS 422 or RS 232. The positioning pulse is also galvanically isolated. Further interfaces are CAN-Bus or Profibus®. An overview of the available variants of the antenna is given in the corresponding table below. Of the transponder antenna there are several variants available. They can be distinguished by the second to last character of the product number, e.g. HG G-98780ZA.
