Ferrous proximity switches

Features

Proximity switches for detecting ferromagnetic materials such as ferrous metals. Not react to such materials as aluminim or nonmagnetic stainless steel.

Mechanism

Sensors are deactivated because magnet is being pushed by springs and the detection circuit is within the N-pole magnetic field.

ferrous mechanism off

When a ferromagnetic object such as ferrous metals approaches the sensing face, magnet is pulled toward the object. Then, the sensing sirsuit detects S-pole and the switch is activated.

WARNING

・Ferrous proximity switches are not suitable for detecting tiny loose terromagnetic

   materials such as  iron powders because they are easily stuck to magnets.

・When mounting a ferrous proximity switch, please check that there ia no

   ferromagnetic material at the back and lateral sides.
