The ZCKM1H29 limit switch body is a compact industrial sensing device designed for reliable position monitoring in automation environments. It combines a dual contact arrangement (1NC + 1 NO) with a snap action mechanism, delivering fast, clear switching and flexible wiring for control and safety circuits. With an M20 threaded mounting interface, this switch body is straightforward to install in panels, machinery frames, and guard housings. Key benefits Dual contacts in one device: 1NC and 1 NO outputs enable simple wiring for both monitoring and control on a single switch body. Snap action switching: Fast, decisive contact movement improves response time and reduces contact wear for longer life. Easy mounting: M20 mounting thread supports standard installation practices and compatible actuators. Compact form factor: Suitable for tight spaces without compromising performance. Industrial applicability: Designed for use in automation environments requiring reliable position sensing and simple integration.
