The RDS80001 and RDS80002 railwheel sensors are 2 wire dc inductive and proximity sensors, specifically designed and constructed for sensing railwheel flanges at speeds up to 500 km/h. There are 2 types of outputs available. Both types are available in high and low frequency versions. RDS80001 ? Sensor output current is proportional to applied voltage. Designed to operate at a nominal 16 Vdc with a 1 kOhm load, which will result in an output of 8 mA with no wheel detected and 2 mA when a wheel is detected.
RDS80002 ? Sensor output current is limited to 2 mA/8 mA within the sensor to allow use of voltage overdrive to counter interconnecting cable losses (10 km +) and still maintain 2 mA/8 mA output without field adjustment.
