The BS300H is a 3-pin Hall-effect sensor with the following functions:
1. VCC (Pin 1) – Power supply (typically 3.5V–24V).
2. GND (Pin 2) – Ground connection.
3. OUT (Pin 3) – Open-collector output (switches to ground when a magnetic field is detected).
It operates as a unipolar switch, activating when the south pole of a magnet approaches and deactivating when the field weakens. Commonly used in position sensing, speed detection, and proximity switching applications.
