The PRND gear sensor is mainly assembled by the rotor and the housing. The rotor cooperates with the customer's rotating shaft and rotates with the rotating shaft. The housing is installed and fixed on the gearbox housing. The rotor contains a magnet, the interior of the housing contains a chip and PCB, and the housing also contains a connector to connect with the vehicle harness.

The rotor inside the sensor drives the magnet to rotate, and the magnetic field sensed by the chip changes. The chip will be converted into internal analog signals according to the change of magnetic field angle. The chip converts the analog signal into digital signal through the processing circuit, and outputs the duty cycle signal.

The gear sensor is a component in the automobile transmission control system. The sensor is installed on the gearbox housing, and the matched shift shaft drives the magnet to rotate together. The sensor outputs different signals through the change of magnetic field radiated by the magnet and feeds back to TCU. PRND gear sensor is practical and applicable to all kinds of automatic gear boxes. At present, it has been supplied in large quantities in major main engine plants.
