The encoder magnet 3 is a device for determining the position or rotation angle of mechanical components by detecting the change of magnetic field. The magnet is usually fixed on the shaft of the mechanical equipment and rotates with the shaft. When the magnet rotates, it will change the magnetic field distribution of the surrounding area. This magnetic field change is captured by the sensor fixed on the base and converted into an electrical signal output.
