What is a sensor magnet? Does the Hall sensor need a special magnet magnet? Which material is the best for Hall sensor magnets? What is the relationship between Hall sensors and magnets? With these magnet questions, let's learn and understand together.
The sensor magnet, that is, the magnet used on the sensor, mainly plays the role of induction.

What kind of magnets are generally used for Hall sensor magnets?
Usually, the sensing magnetic steel is mostly bonded injection-molded magnetic steel, and the magnetic ring is mostly used for automobile range meter sensors, tachometer sensors, etc. Generally, plane multi-pole magnetization, radiation multi-pole magnetization and axial magnetization are used, and the magnetic performance is 500 ~2000GS, our sensing magnetic steel has the advantages of being strong, firm (not easy to fall off and deform), uniform density, and good magnetic field consistency.
Does the Hall sensor need a special magnet?
This is not needed, as long as the magnetic force is strong enough that the Hall element can sense it.
What are the components of a hall sensor?
It is generally composed of a Hall element and a magnetic steel. When the Hall element and the magnetic steel move relative to each other, a signal pulse will be generated, and the rotational speed can be calculated according to the magnetic steel and the number of pulses.
