EA120 Series
Magnetic Proximity Sensors

Non-contact magnetic proximity switches are used to detect the position of mechanical motion and provide accurate position indication. An actuator, in the form of a target magnet, passes in front of the proximity switch, engaging the switch, and allowing the internal electrical contacts to change state. The application is never in physical contact with the proximity switch. Applications that typically use limit switches include valve position indication, sorting, level detection and many safety related situations.
