The XCNR range is an offer of compact plastic limit switches with reset for general use. The XCNR2118P20 limit switch is composed of a fixed plastic body and a rotary plastic head. The fixing is done by the body. It has a thermoplastic spring return roller lever operator with a lateral approach (2 directions). The movement of operating head is rotary. It has one normally closed and one normally open snap action contacts with positive opening operation. It has one cable entry tapped for M20 x 1.5mm cable gland and it is powered by screw-clamp terminals (clamping capacity : 1 x 0.34…2 x 1.5mm²). The contactor can perform an average of 100 thousand no-load operating cycles without mechanical failure. The XCNR2118P20 limit switch is made of a plastic body and a plastic head. This limit switch complies with UL, CSA, and CCC standards, and its protection level complies with IP65 (resistant to dust and water jets). Telemecanique Sensors limit switches are ideal for industrial environments : they are precise, robust, reliable, easy to install and offer high repeatability. A limit switch is a device that converts a mechanical motion into an electrical control signal
