The SS445P Hall Effect Sensor from Honeywell comes in a subminiature package size, consuming lesser space on the PCB and in smaller assemblies. Hall effect sensors operate as analog transducers and return a voltage directly on being triggered by a magnetic field. They also vary their output voltage in response to a magnetic field.

The embedded tape and reel packaging permits automated component placement, which reduces manufacturing costs. Featuring a built-in pull-up resistor, this Honeywell Sensor can be easily interfaced with common electronic circuits. This unipolar hall sensor is used in a variety of industrial, transportation and medical applications like medication bin monitor on portable drug carts, printer head position sensing, door or lid closure detection in appliances, and robotic control, among others.
