The Zamak zinc alloy body and IP66 / NEMA 4 enclosure mean it handles washdown and outdoor exposure without a secondary cover — that's the same rating you'd spec for a food-processing line or a car-wash bay. Contact rating is 10 A at 240 VAC and 0.27 A at 250 VDC, SPDT configuration. The AC side handles typical motor-starter or relay-coil loads; the DC side is low-current — 0.27 A at 250 VDC is about 67 W, so it's fine for a PLC input or a small DC solenoid, not a DC motor contactor. The spring-return snap-action gives a clean break, which helps with DC arc extinction at that voltage. The rotary head with a Delrin roller lever gives 23° pretravel and 90° total travel, with 11° differential travel. That means the lever has to move about a quarter-turn before the contacts flip, and the deadband between make and break is about 11°. It's a standard feel for a roller-lever limit switch — predictable for cam-actuated sequences. Approvals include UL and CSA, plus it's built to EN/IEC 60204-1 and EN/IEC 60947-5-1. ## Connection and mounting Termination is through a PG13.5 cable gland with screw-clamp terminals inside. That's a metric thread — common in European-sourced panels — so you'll need a PG13.5 cord grip or conduit adapter. The non-plug-in body means the cable enters directly; there's no separate base to swap if the switch fails, but it also means one less potential leak path in wet locations. Operating temperature range is -13 to 158 °F (-25 to 70 °C). That's fine for most indoor and outdoor enclosures in temperate climates; if you're mounting it on a freezer door or a kiln, check the ambient at the actuator.","metaTitle":"Square D XCKJ10511 Heavy Duty Limit Switch, 10A 240VAC, IP66","metaDescription":"Square D XCKJ10511 heavy duty limit switch. 10A at 240VAC, SPDT, IP66/NEMA 4.
