A3144 is a 3-pin TO-92 packaged digital Hall Effect sensor that can be used in many types of magnetic field detection and speed/position sensing applications. It is commonly used for RPM measurement, proximity sensing, motor speed sensing, and contactless switching. For using it as a switch output sensor, it can handle up to 25mA output current with a 4.5V to 24V supply range.
