The structure of the sensor magnet is relatively simple. Generally, the magnet, embedded ring and plastic injection molding are used to achieve the function of installation and positioning. Some magnets installed in the piston shaft will be more simple. They are just a simple magnet, and the surface is plated with nickel, copper and nickel to prevent rust and enhance the toughness of the material.

The sensor magnet is generally matched with the corresponding sensor. It is generally used for the position sensor in the gearbox to provide the magnetic field. The core component of the position sensor is the position chip, which can monitor the change of magnetic field angle or magnetic field strength and produce different output signal values. The sensor magnet is generally installed on the measured object, such as shift fork, shift shaft, solenoid valve, etc, The movement of the shift fork will drive the corresponding movement of the sensor magnet, while the position sensor is generally fixed, so the magnetic field intensity or magnetic field angle felt by the position chip will change, so as to output the corresponding duty cycle or voltage value. TCU identifies whether to move to the preset position by comparing with the calibrated parameters.
