Features Applications ■ Non-contacting sensor technology ■ Park lever position detection ■ MR or HE technology ■ Electric park brake ■ Sensor can be placed outside of the gearbox ■ Linear option also available ■ Electronic calibration Rotary Gearbox Park Position Sensor Introduction The Bourns® Rotary Gearbox Park Position Sensor senses the rotary or linear displacement of the park lever in an automatic gearbox application. When the park position is selected in the gearbox, the park engagement pin shifts to lock the transmission. The feedback from this sensor works in conjunction with the TCU to ensure that the park lever is released only if the brake pedal is depressed. This prevents a vehicle from lurching forward if started in gear. The sensor may be placed internally or external to the gearbox depending on the available space. The signal may be used to decouple the torque converter to save fuel and/or to trigger the engagement of the Electro-Mechanical Park Brake (EMPB).
