The XCR ATEX limit switches range is designed for hoisting and material handling applications. The XCRB151EX limit switch is composed of a fixed body and a rotary head. The fixing is done by the body. It has a thermoplastic spring return large roller lever operator with a lateral approach (2 directions). The movement of operating head is rotary. It has twice one normally closed and one normally open snap action contacts with positive opening operation. It has one cable entry tapped for Pg 13.5 cable gland (included) 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 10 million no-load operating cycles without mechanical failure. The XCRB151EX limit switch measures 95mm in height, 85mm in width, and 75mm in depth. This limit switch complies with INERIS 04ATEX0014X and IEC-Ex INE 16.0048X 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
