Additional Details

The SS40AF-1 Hall-effect sensor operates by detecting the presence of a magnetic field perpendicular to the sensor's surface. When the magnetic field exceeds a specific threshold, the sensor outputs a digital signal, indicating the presence of the field. The sensor is designed to be highly resistant to mechanical stress and environmental factors, ensuring reliable performance in demanding applications. It typically requires a pull-up resistor on the output signal for proper operation. The sensor is commonly powered by a 4.5 Vdc to 24 Vdc supply.
