XCKN2118P20C (XCKN2118P20) is a 240V 3A limit switch from the XCKN series. It uses a snapaction mechanism and provides 1NC+1NO contacts in an M20 mounting body, delivering compact and reliable position sensing for automation applications. Key benefits Fast, precise actuation with snapaction switching for repeatable operation. Dual contacts (one normally closed and one normally open) enable simultaneous signaling and control from a single device. M20 threaded housing offers flexible mounting in tight or confined spaces. Rated for 240V and up to 3A, suitable for common control circuits in automation. Brandaligned design that fits within the XCKN family for predictable compatibility and performance. Key attributes Series/model: XCKN; XCKN2118P20C / XCKN2118P20 Electrical rating: 240V, 3A Contact arrangement: 1 NC + 1 NO Actuation: Snapaction Mounting: M20 Type: Limit switch Applications Endoftravel sensing on conveyors, linear actuators, and other automation equipment.
