Its NEMA 1/2/4/12 and IP66 enclosure means it seals out hose-directed water and airborne dust — suitable for food-processing lines, machine tools, and outdoor conveyor systems where a standard limit switch would fail from ingress. Contact rating is 240 VAC 10 Ampere and 250 VDC 0.27 Ampere (SPDT, snap-action). The AC figure governs motor-control circuits and solenoid loads; the DC figure is derated significantly because DC arcs are harder to extinguish — at 250 VDC the switch is limited to 0.27 A, so it will not handle a typical 24 VDC sensor load above that current. For DC control circuits, verify the load current stays under the 0.27 A limit at the applied voltage. The top rod plunger actuator (spring return, snap action) provides a direct mechanical interface for cam- or slide-actuated positions. Pretravel is 0.08 inch, differential travel 0.035 inch, total travel 0.24 inch — the narrow differential means the switch changes state with minimal overtravel, useful for precise position detection on indexing tables or press slides. ## Construction and integration Body is Zamak zinc alloy, corrosion-resistant and dimensionally stable under vibration. Connection is via a PG13.5 cable gland with screw-clamp terminals — the gland accepts standard 1/2-inch trade-size conduit or cable, and the screw clamps handle solid or stranded wire up to about 14 AWG. No plug-in base; wiring is direct to the switch body, so replacement requires rewiring at the terminal block. Operating temperature range is -13 to 158 °F (-25 to 70 °C), covering most indoor and sheltered outdoor installations. The switch carries UL and CSA approval, plus compliance with EN/IEC 60204-1 (machine safety) and EN/IEC 60947-5-1 (control circuit devices). These standards are the baseline for industrial control panels in North America and Europe.","metaTitle":"Square D XCKJ161 Heavy Duty Limit Switch, SPDT, 240VAC 10A,","metaDescription":"Square D XCKJ161 heavy duty limit switch, SPDT, 240VAC 10A / 250VDC 0.27A, NEMA 1/2/4/12 IP66, Zamak body, UL/CSA.
