Roller-lever position feedback on conveyors and guard doors
The XCKP2118N12 is the XCKP compact form factor in the Osiswitch line, built around a thermoplastic roller lever that wipes over a cam or strikes a hinged guard to give a clean open/closed signal back to a PLC or safety relay. It carries 1NO-1NC snap-action contacts rated 240 VAC at 10 A and 250 VDC at 0.27 A, which covers the standard motor-starter coil, relay, and indicator-load switching jobs on a packaging, material-handling, or door-interlock circuit without an interposing relay.
Travel geometry and the operating-force budget
Pretravel is 25°, differential travel is 12°, and total travel is 90°, so the switch trips well before the actuator reaches its mechanical end-stop and resets with a defined hysteresis band — the figure that actually drives repeat-positioning tolerance on a conveyor lug or guard strike.
Sealing for washdown and outdoor mounting
The enclosure is rated NEMA 1, 2, 4, 6, 6P, 12 and 13, plus IP66 and IP67, which is the combination that lets the same XCKP2118N12 sit on an indoor panel door, an outdoor conveyor frame, or a food-and-beverage washdown zone without re-specifying the switch. Wiring lands through a 1/2 inch NPT conduit entry with screw-clamp terminals, so the conduit drop and the cable gland lock against the same thread the switch ships with — no extra adapter needed at install. Operating temperature spans -13 to 158 °F, covering unheated warehouses and most process-area ambients without a heater or sun-shield accessory.
Standards coverage and approvals
The XCKP2118N12 carries UL and CSA approvals and is built to EN/IEC 60204-1 and EN/IEC 60947-5-1, so it sits cleanly inside the control-circuit section of a machine whose overall safety and electrical design is documented to those standards — the certifications a buyer needs to close out the declaration of conformity.
