ZCKM1H29 and ZCKM1H29C limit switch bodies are compact, reliable components for endoftravel sensing in automated equipment. Featuring a snapaction mechanism and a 1 NC plus 1 NO contact arrangement, these switches provide fast, decisive switching and flexible wiring options in tight spaces with M20 mounting. Key benefits Dual contact configuration (1 normally closed + 1 normally open) enables flexible wiring and control logic without needing additional switches. Snapaction operation delivers fast actuation, clear electrical signals, and improved repeatability for higher cycle life. Compact M20 mounting supports installation in cramped or spaceconstrained areas, helping to simplify panel design and wiring. Robust switch body design geared toward industrial automation environments, offering dependable performance in routine production settings. Key attributes Model variants: ZCKM1H29 and ZCKM1H29C Type: limit switch body Contacts: 1NC + 1NO Action: snap action Mounting: M20 threaded Applications and use cases Endoftravel sensing on packaging or processing equipment to reliably indicate full stroke and trigger downstream control. Position sensing on conveyors or material handling lines to index operations or coordinate multiple stations. Integration into automation circuits where both a normally closed and a normally open contact are required for control logic or signaling, enabling simple and reliable interconnections.
