The Square D XCKJ110541 is a heavy duty plug-in limit switch from the Osiswitch line, built for industrial environments where reliability under washdown and dust exposure matters. It carries a SPDT contact block rated 10 A at 240 VAC and 0.27 A at 250 VDC — the AC side handles most control-circuit loads on a line, while the DC rating is low enough that you'll want to verify it against your specific solenoid or valve draw before committing the BOM line.
Enclosure and approvals
Rated NEMA 1/2/4/12 and IP66, so it stands up to hose-down cleaning and airborne particulates common on food, beverage, and packaging lines. UL and CSA listed — accepted across North American panels without a secondary evaluation. The ZAMAK zinc alloy body resists corrosion better than painted steel in wet environments.
Actuator and mounting
Rotary head with an adjustable DELRIN roller lever — the lever position can be rotated in 90° increments to match the cam or dog approach angle. Spring-return snap-action operation gives positive break, so it meets the forced-opening requirement of EN/IEC 60947-5-1 for safety circuits. Connection is via a PG13.5 cable gland with screw-clamp terminals; strip length around 8 mm and you're good for 0.2–2.5 mm² stranded or solid.
