Schneider Electric Telemecanique ZCMD21 Limit Switch

The Schneider Electric Telemecanique ZCMD21 is a miniature modular limit switch body in the OsiSense XC Standard family, housing a 2-pole snap-action block with 1 NC and 1 NO contacts in a Zamak metal housing for reliable end-of-travel sensing and machine control. Designed to accept interchangeable ZCE actuator heads and ZCMC plug-in connection modules, it supports widespread automation uses—from conveyors and packaging lines to machine tools, material handling equipment, and automated production systems—while offering long service life in industrial environments. Key specifications include plug-in electrical connection via ZCMC modules, silver-plated contacts, positive opening, and compatibility with the XCMD Series; it lists compatible ZCMC modules as ZCMC21L1, ZCMC21L2, ZCMC21L3, ZCMC21L5, ZCMC21L7, ZCMC21L10, ZCMC21E1, ZCMC21E2, ZCMC21E3, ZCMC21E5, ZCMC21E7, ZCMC21E10, ZCMC21T1, ZCMC21T2, ZCMC21T5, and actuator heads such as ZCE01, ZCE02, ZCE05, ZCE06, ZCE07, ZCE08, ZCE09, ZCE10, ZCE11, ZCE13, ZCE14, ZCE21, ZCE24, ZCE27, ZCE28, ZCE29, ZCE62, ZCE63, ZCE64, ZCE65, ZCE66, ZCE67, ZCEF0, ZCEF2, ZCEG1, ZCEH0, ZCEH2.
