Red Lion Magnetic Pick Up Permanent Magnet

The Red Lion Magnetic Pickup Sensor consists of a permanent magnet, a pole piece and a sensing coil encapsulated in a cylindrical case. An object of iron, steel or other magnetic material, passing closely by the pole piece causes distortion of the magnetic flux field, which in turn generates a signal voltage. The magnitude of the signal voltage depends on the relative size and magnetism of the target, its speed of approach, and how close it passes the pole piece. Magnetic pickup sensors are most frequently used to sense passing teeth on a gear, sprocket, or timing belt wheel.
