Transponder Reader HG 70640YC and Transponder (Balise) HG 70610RE are used in railway applications. This system enables transmitting a unique, position de- pending transponder code punctually. The Reader is installed underneath the train, the Transponder (Balise) is installed within the road bed, preferrably onto a sleeper. The nominal reading distance between reader and Transponder is 400 mm. The Transpon- der crossing speed can be up to 100 km/h.
When crossing the Transponder, the Reader energizes the Transponder inductively with energy. At any other time, the Transponder is passive and does not require any power supply.
