TMSS GERMANY Schneider Electric ZCMD29 Limit Switch Body, 2 NC, Snap Action, Zamak

Industrial machine builders and maintenance technicians use the ZCMD29 limit switch body as the electrical interface for position detection in automated equipment. This body accepts a separate ZCMD series operating head (not included) to form a complete limit switch. The body provides two normally closed (NC) contacts with snap action, ensuring rapid switching even at slow actuation speeds. Its die-cast zinc (Zamak) housing withstands harsh industrial environments, and the screw clamp terminals allow secure wiring. The cable entry is tapped for M16 x 1.5, enabling use with standard cable glands or conduit fittings.

Why choose it

The ZCMD29 offers proven reliability in demanding automation applications. Its snap action contacts ensure consistent performance even with slow-moving actuators, and the Zamak housing provides excellent mechanical strength. The wide operating temperature range and tropicalisation treatment make it suitable for challenging environments. With high electrical and mechanical durability, it reduces maintenance frequency and downtime.

Ideal use cases

• Position sensing on machine tools and conveyor systems
• End-of-travel detection in packaging machinery
• Safety interlock circuits (when used with appropriate heads and safety modules)
• Industrial automation requiring robust limit switches

Good to know

This is a limit switch body only; a compatible ZCMD series operating head must be ordered separately. The body is designed for use with standard M16 cable glands. It is not a complete switch and cannot function without a head. The product is part of the Schneider Electric OsiSense XC Special range, known for modularity and flexibility.
