This RS PRO plunger-type limit switch features two connections – one NO (normally open) and one NC (normally closed). When an object pushes the plunger down, the switches change position, allowing you to detect or count the objects or monitor their limit of travel.


The limit switch has a double-insulated thermoplastic casing for increased safety and protection. It also has an IP67 rating, so it's dust-tight, touch-proof and resistant to temporary immersion in up to 1 m of water.


This product won't interfere with the operation of sensitive electronic equipment or components as it meets international electrostatic control standards. It's pre-wired with a polyvinyl chloride (PVC) cable for easy installation.
