It provides one normally-closed and one normally-open contact in a DPST configuration, rated for 240V ac circuits. The IP66 rating means the switch is sealed against dust ingress and powerful water jets — suitable for washdown environments on packaging lines, conveyor systems, or machine tools where coolant spray is present. The Zamak alloy housing handles vibration and impact better than a plastic enclosure, so it holds up on moving machine guards or transfer stations. The 1NC/1NO contact arrangement is the standard form for safety-related limit switches: the NC channel provides a positive-break signal for the safety circuit, while the NO channel reports position to the PLC. The DPST configuration means each contact is electrically isolated, so you can wire them to separate circuits without shared commons. ## Where this class of part is used Roller lever limit switches like this one are the workhorse position detectors on industrial machinery — they confirm carriage travel limits, detect valve position, signal door closure, and trigger end-of-stroke actions on automated lines. The roller lever actuator handles cam-operated or sliding-surface applications where a plunger would wear or jam. The current lifecycle status means you can freeze this part into a new design without worrying about near-term obsolescence.","metaTitle":"XCKJ50511H29SCH Roller Lever Limit Switch, 1NC/1NO, IP66, 24","metaDescription":"XCKJ Series roller lever limit switch, 1NC/1NO, DPST, IP66, Zamak zinc alloy housing, 240V ac.

If you need the same roller lever but with different contact arrangement (e.g., 2NC or 2NO), look at the XCKJ range. For a different actuator type like plunger or whisker, the XCKP or XCKN sub-series are the mechanical equivalents within the same housing platform."},{"question":"What compliance documentation is available for this part?","answer":"The XCKJ Series typically carries UL, CSA, and CE certifications for industrial control equipment.
