Schneider Electric Telemecanique ZCMD21 Limit Switch

The Telemecanique ZCMD21 Limit Switch is a miniature plug-in limit switch body in Schneider Electric’s XC Standard (OsiSense XC) family, designed for reliable end-of-travel sensing in industrial automation equipment. It uses a durable Zamak housing with snap-action, silver-plated contacts (1 NC + 1 NO) and is intended for use with interchangeable ZCE operating heads and ZCMC plug-in connectors, enabling retrofit or expansion on conveyors, packaging machinery, machine tools, and material handling lines. Key specifications include 2 poles with a 1 NC + 1 NO contact configuration and positive opening, plug-in electrical connection (no pre-wired leads), contact resistance of 25 mΩ, IEC 60947-5-1 compliance, AC-15 rating of 240 V AC, 1.5 A (B300) and DC-13 rating of 250 V DC, 0.1 A (R300); housing protection IP66/IP67 when assembled with a compatible head and connector. Common applications are end-of-travel detection, machine sequencing, position monitoring, and automated process control within conveyors, packaging lines, tools, and material handling systems, with compatibility to the XCMD Series and a broad range of ZCE heads and ZCMC connectors.
