The XCKN2118P20C (also listed as XCKN2118P20) limit switch features a thermoplastic roller lever and a snap action mechanism for reliable position sensing in compact form. It provides two contacts in a 1NC + 1NO configuration and is designed for easy mounting in an M20 enclosure. Key benefits Reliable sensing with a snap action mechanism for fast, decisive switching and reduced contact wear. Flexible wiring options thanks to two contacts: one normally closed (NC) and one normally open (NO), enabling simple integration into control and safety circuits. Compact, lightweight thermoplastic construction suitable for industrial environments, with a roller lever to minimize wear and provide smooth actuation. Easy mounting with standard M20 thread, facilitating quick installation in machines and equipment. Key attributes Model: XCKN2118P20C (also listed as XCKN2118P20) Actuator: thermoplastic roller lever for smooth engagement Contacts: 1 normally closed (NC) + 1 normally open (NO) Mechanism: snapaction for fast, reliable switching Housing: thermoplastic body Mounting: M20 threaded installation Functional benefits Two independent contacts in a single switch provide versatile wiring for independent control or safety circuits. The roller lever reduces impact and wear on both the switch and the actuated part, extending service life in dynamic environments. Snapaction ensures quick and repeatable operation, improving detection accuracy and machine response times. Compatibility and use cases Endoftravel detection on conveyor or assembly lines: mount the switch at the stroke end to trigger a stop or cycle control via the NC contact, while the NO contact can drive a secondary signal or interlock. Safety interlock or guard monitoring: use the NC contact to hold a safety circuit closed when in normal position, and the NO contact to initiate an auxiliary alarm or next step when actuated. General position sensing in automated equipment: the compact M20 footprint allows installation in limited spaces where precise endoftravel sensing is needed. Notes The product combines a thermoplastic roller lever with a snapaction mechanism in an M20 sized housing, suitable for various industrial applications requiring reliable limit switching. Twocontact, SPDTlike configuration (1NC + 1NO) supports flexible wiring for control and safety logic without needing additional components. This description reflects the brand, model, and features of the XCKN2118P20C / XCKN2118P20 limit switch, including its thermoplastic roller lever, 1NC+1NO configuration, snapaction mechanism, and M20 mounting.
