This sensor uses a magnet to send throttle or brake position data to your MyChron4 kart data logger.
Simply install the magnet on the pedal (near the pivot) and install the sensor in front of the magnet on the chassis. Connect the sensor to your MyChron4 Expansion box and calibrate using the MyChron4 calibration page.
Measures up to 35mm of pedal travel (magnet-to-sensor distance must be no less than 5mm at full throttle and no more than 40mm at zero throttle). Can be used on either brake or throttle pedal. Requires eBox, sold separately. Kit includes sensor, magnet, bracket kit, and 1 meter (3 ft) 719-to-712 (4-pin) adapter cable.
