A3144 Hall Effect Sensor TO-92 (Magnetic Switch, Hall Sensor IC)

The A3144 Hall Effect Sensor is a digital magnetic sensor designed to detect the presence of a magnetic field and provide a switching output. Operating as a unipolar Hall-effect switch, the output changes state when a magnetic field of sufficient strength is applied. Its contactless operation, high reliability, and fast response make it ideal for automation, speed sensing, position detection, and magnetic proximity applications.
