Magnetic proximity sensors

Magnetic proximity sensors

The magneto-resistive element is made of a special material which only reacts to magnetic fields, for example a permanent magnet, and provides a digital signal at the output. Detecting even very weak magnetic fields, the magneto-resistive element is approximately ten times more sensitive than a Hall element which enables a large switching distance. Magnetic proximity switches are omni-polar, meaning both North and South pole are being detected.
