Schneider Electric XCK-PH7 Safety Interlock Switch

The Schneider Electric XCK-PH7 safety interlock switch is a heavy-duty, fixed-body, rotary-head interlock device from the XC Standard XCKP family, designed for machine guarding, position detection, and safety interlocking in industrial automation. Built with a metal Zamak body and head, its rotary operating head is actuated by a 30° cam and paired with a spring-return roller lever for reliable action. It provides 1 NC + 1 NO contacts and slow-break operation (model dependent), with screw-clamp terminals for wiring and a lateral approach available in 1 or 2 directions depending on the model. Common applications include machine guards, conveyors, packaging equipment, automated assembly equipment, machine tools, and material handling systems that require dependable roller-operated safety switching. Common replacements in the XC Standard XCKP series include Telemecanique XCKP2118G11 and Telemecanique XCKJ50513H7.
