The ZCKM1H29 and ZCKM1H29C limit switch bodies are compact, reliable sensing components designed for endoftravel and position monitoring in automation and machinery. Featuring a snap action mechanism and a dual contact configuration, they provide clear, fast switching signals from a single compact package. The mounting size is M20, supporting standard limit switch installation hardware. Key benefits Dual signaling in one device: 1 normally closed (NC) and 1 normally open (NO) contact, enabling simple control and monitoring of two circuits or logic states from a single switch. Snap action for fast, crisp switching and reduced contact wear, improving reliability in cycling applications. Compact M20 mounting: fits into tight spaces and aligns with common limit switch mounting standards. Clear, immediate feedback for endoftravel or position sensing, helping protect machinery and optimize automation sequences. Simple integration into control circuits without the need for additional adapters or special accessories. Key attributes Models: ZCKM1H29 and ZCKM1H29C Type: Limit switch body Contacts: 1 NC + 1 NO Action: Snap action Mounting: M20 Applications and use cases Endoftravel sensing on automated axes, such as CNC machine carriages or robotic arms, to stop motion at a defined position. Position monitoring on conveyors or packaging lines to trigger downstream processes or halt operation when limits are reached. Safety interlock or dualsignal signaling in machinery where both NO and NC outputs are used for separate control circuits or safety circuits. Compatibility and installation notes Mounting compatible with standard M20 limit switch installations and related hardware. Designed to be used as a limit switch body in automation setups requiring a 1NC+1NO, snap action configuration.
