Additional Details

The SS40AF-2 Hall-effect sensor operates based on the principle of the Hall effect, where a voltage difference is produced across an electrical conductor transverse to a magnetic field. The sensor outputs a digital signal when the magnetic field exceeds a specific threshold, indicating the presence of the field. It is designed to be highly resistant to mechanical stress and environmental factors. It typically requires an external pull-up resistor for proper output. The sensor's supply voltage typically ranges from 4.5 Vdc to 24 Vdc.
