SJS2 Start Judge Sensor

A Start Judge sensor is connected to each starting block. The sensor is triggered by movement. The system checks the start signal with each sensor impulse. If a sensor impulse occurs before or within 1/10 of a second after the start signal, a false start signal is triggered. The Start Judge SJ2 works with cable or radio connection (proven ALGE-TIMING WTN system).
