The working principle of the circuit:
The quiescent output voltage (B=0GS) is half the supply voltage. When the S magnetic pole appears on the marking surface of the Hall sensor, it will drive the output above zero level. The N pole will drive the output below zero level. The instantaneous and proportional output voltage levels determine the magnetic flux density at the most sensitive side of the device. Increasing the supply voltage increases sensitivity.

Instructions for use:
1. Minimize the mechanical stress applied to the circuit casing or leads during installation.
2. The welding temperature should be lower than 260°C, and the time should be less than 5 seconds.
3. If the N pole approaches the Hall circuit from the back, the output voltage decreases, and the S pole approaches from the back, and the output increases. If approached from the front, the output state is just opposite to that of approaching from the back.
