A gear sensor, also known as a gear switch sensor, is generally equipped in an automatic transmission and is mainly used to detect gear signals. It is usually assembled from the rotor and housing, and the rotor includes a magnet part. So what role does the magnet play in it? What is the material of the magnet?

Magnets mainly serve to provide a magnetic field and are mostly made of injection molded magnetic (plastic magnetic) materials. 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 magnetic field changes emitted by the magnet, which are fed back to the TCU.

The above is an introduction to the functions and materials of magnets in automotive gear sensors. Our company is a professional supplier of motor magnets, providing processing and manufacturing of various sensors and encoder magnets. We can produce multipole magnets with various performance and materials according to customer drawings and technical requirements. If you need samples, friends who evaluate the price of magnets are welcome to call for consultation.
