The Square D XCKD3918G11 is a compact limit switch from the Osiswitch line, built for general-duty position sensing in wet or dusty environments. It carries a 1NO-2NC contact block rated 10 A at 240 VAC and 0.27 A at 250 VDC — the AC rating handles most motor-starter and relay coils; the DC rating is low, so inductive DC loads like solenoids need derating or a suppression diode. The ZAMAK metal body and IP66/IP67 enclosure (NEMA 1/2/4/6/12/13) mean it shrugs off washdown, dust, and temporary submersion — standard for food-and-bev or machine-tool coolant zones. The thermoplastic roller lever actuator gives a positive snap-action break, and the PG11 cable gland with screw-clamp terminals keeps field wiring simple without a separate connector.
