Types of Magnetic Proximity Switches
Magnetic Proximity Switch Reed Type, With Actuating Magnet
These switches require a magnet for operation. The magnet is supplied with the switch. The reed element which is sealed in the switch operates when the magnet passes nearby.

Magnetic Pick-Ups
Magnetic pick up consists of permanent magnet, a pole piece and a sensing coil and electronic circuit. An object of iron, steel or other magnetic
material passing closely by its pole face causes distortion of its magnetic flux field passing through sensing coil and pole piece, which in turn
generate a signal voltage
Application : Magnetic pick ups are most widely used to sense teeth of a gear, timing belt wheel even bolt head, key-ways.
