That means it handles indoor washdown, outdoor rain, and the dust and oil mist common on a packaging or material-handling line — no extra cover needed. The thermoplastic roller lever actuator is the standard cam-follower style you see on conveyor diverters, pallet stops, and machine guard positions. ## What the contact ratings actually mean for your circuit The XCKJ50511 is rated 240 VAC at 3 amperes and 250 VDC at 0.27 ampere. The switch meets UL 508 (industrial control equipment), CSA C22.2, CE, and CCC — so it is accepted for North American panels and for machinery exported to Europe and China. It also references EN/IEC 60204-1, the machinery safety standard, which matters when the limit switch is part of a guard interlock circuit. The fixed body measures 1.57 in wide by 1.73 in deep by 3.03 in high. Connection is through a 1/2 inch NPT conduit entry. Operating temperature range is -13 to 158 °F.","metaTitle":"Square D XCKJ50511 Limit Switch, 240 VAC 3 A, NEMA 4/12, IP6","metaDescription":"Square D XCKJ50511 heavy duty limit switch.
