Telemecanique XCKJ10541D Limit Switch, IP66, M12

XCKJ10541D is a surface-mount limit switch from the Telemecanique XCKJ series, fitted with a side roller lever actuator. It carries 1NO/1NC contacts rated 4 A at 240 V AC and DC—the same rating for both duty types, so no derating between resistive and inductive loads at that voltage. The M12 5-pin connector keeps wiring to a single quick-disconnect cable, which simplifies replacement on machines where panel access is tight. Sealing is IP66 and NEMA 1/2/4/12/13, meaning the switch handles hose-down environments and dust exposure without an auxiliary boot. It's also listed to UL 508, CSA C22.2 No.14, and EN/IEC 60947-5-1, so it passes a standard panel builder's compliance checklist. Mechanical travel is 90° total, with a maximum operating torque of 2.21 in-lb. Body dimensions keep the mounting hole pattern at 60 mm vertical by 30 mm horizontal (four holes, 0.21 in diameter) and fit the existing footprint of standard XCK-J enclosures.
