Additional Details

The SS43AF 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. This sensor is typically powered by a DC voltage ranging from 4.5 to 24 V. An external pull-up resistor is often required for proper operation of the output signal. The sensor's consistent performance and durability make it a reliable choice for a wide range of applications.
