Telemecanique ZCK D21 Limit Switch Head Roller Lever

The Telemecanique ZCKD21 Limit Switch Head mates with XCKM or XCKL-series switch bodies to provide reliable position sensing via a spring-return thermoplastic roller lever plunger. It employs a lateral, one-direction actuation driven by a 30° cam and offers a plastic thermoplastic head with positive opening, suitable for linear or rotary movement. As part of the XC Standard family (device short name ZCKD), this head is compatible with XCKM and XCKL bodies and rated for standard industrial environments, weighing approximately 0.085 kg. Typical applications include machine tools, conveyors, packaging equipment, and material handling systems, where repair, retrofit, expansion, or replacement of XC Standard limit switch assemblies is needed.
