The S251 provides all of the RF and control functions required to communicate with HDX LF transponders. The main task of the Reader is to send a power pulse via the antenna to initialize the transponder, to demodulate the received identification signal and then send the data to a control device. It is also used for sending programming data to Read/Write including Multipage transponders. It features dynamic autotuning.
The Reader is housed in an IP20 Polycarbonate box.
