Hall speed sensor magnet is mainly used in locomotive control system to provide necessary guarantee for vehicle driving safety. Its working principle is that when the rotating mechanism of the sensor rotates under the action of external drive, it will drive the permanent magnet to rotate. The magnetic field passing through the Hall element will produce periodic changes, causing changes in the output voltage of the Hall element. A stable pulse voltage signal is formed through subsequent circuit processing, As the output signal of the vehicle speed sensor.
What magnet is used for speed sensor?

Generally, injection molding magnets are used for automobile speed sensors, such as injection molding NdFeB multipolar rings, injection molding ferrite multipolar magnetic rings, and sintered ferrite radial multipoles, which are generally 4 or 8 pairs of poles (8 poles and 16 poles). We have produced magnets of these materials.
What specification is used for the speed sensor magnet?
There are many specifications. The magnet materials and magnetic force required by different customer groups are different. such as
1. D25.5 * 6.1 * 5.3/radial externally filled 4-pole, about 550 Gauss
2. Injection molded ferrite D24 * 16 * 5.65/diameter outer 8 poles
3. Radial externally charged 16 pole polished ferrite D16 * 10 * 9
