The Square D XCKD2106N12 is a limit switch from the XCKD series, built with a cat whisker actuator that detects objects from any direction — omnidirectional 90° total travel. That means it catches parts or pallets approaching from the side, top, or at an angle without needing the target to hit a specific face, which simplifies mounting on conveyor edges or machine in-feed chutes. Rated 10 A at 240 VAC for motor-duty switching, so it handles small conveyor drives, solenoid valves, or indicator loads directly without an interposing relay. The DC side derates sharply — 0.27 A at 250 VDC — so for DC control circuits you'll want to check the inrush of whatever coil or lamp it's switching. IP67 rating means the switch body seals against dust ingress and temporary immersion — fine for washdown zones in food processing or outdoor material handling. The NEMA enclosure ratings (1, 2, 4, 6, 12, 13) back that up for North American installs: NEMA 4 covers hose-down, NEMA 6 covers submersion, NEMA 12/13 covers industrial dust and oil.
Approvals include CE, CSA, and UL Listing, so the switch qualifies for panels destined for European, Canadian, and US markets without a separate certification round.
Surface-mount body with two 0.17-inch mounting holes on 19 mm centers. The Zamak body is shock- and vibration-resistant, which matters on press lines or vibratory feeders where a plastic-bodied switch would fatigue. Contact form is 1NO/1NC, so it can be wired as a safety input (NC channel to the safety relay, NO to the PLC) or as a single-pole changeover for position feedback. The cat whisker actuator extends 5.19 inches from the body — long enough to reach into a chute or past guarding without the switch body itself protruding into the hazard zone.
