AIM ABS Honeywell - Hall Speed Pick up 719 30CM

The M12 Hall Speed Pickup with 719 binder connector. The output varies when it meets a magnetic field. The three-wire sensor produces a digital signal.   

The sensor contains three wires and produces a digital signal. The sensor consists a thin piece of metal what passes a continuous current through it.

When the sensor is placed in a magnetic field the electrons move to one side of the metal and protons move to the other side of the plate. Then you will be able to get a voltage.

The sensor only produces around seven volts. When the electrons move to one side a potential difference is produced between the two sides of the metal.
