Magnetic Proximity Switch Manufacturers and Suppliers

The ‘reed’ contact of the switch changes when operating magnet passes-by within the sensing range of the switch. The magnetic pickup will generate signal when geared wheel rotates. These switches require a magnet for there 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 consist 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 gear, timing belt wheel even bolt head, key-ways.
