Switch

Hall IC(Switch) are divided into omnipolar and unipolar.
The omnipolar Hall IC can sense both the S pole and the N pole of the magnet, and the unipolar Hall IC can only sense the S pole or the N pole of the magnet.
The magnet is close to the IC sensing surface and the magnetic field reaches the conduction point (BOPx), and the output pin is turned on.
The magnet is far away from the IC sensing surface and the magnetic field reaches the release point (BRPx), the output pin is cut off.
The omnipolar Hall IC has low-voltage operation and micro-power functions.
