Limit switch for washdown and industrial positioning
The Square D XCKM102H7 is a limit switch from the XCKM series, fitted with a roller plunger actuator for linear cam or slide detection. The 1NO/1NC contact block gives you one normally-open and one normally-closed set, which is the standard arrangement for interlocking a guard door or signaling a position change while maintaining a closed-loop feedback path. Rated for 3 A at 240 V AC and 0.27 A at 250 V DC, it handles pilot-duty control circuits on conveyors, packaging machines, and material-handling lines. The Zamak body and NEMA ratings 1, 2, 4, 12, and 13 confirm it holds up in industrial atmospheres with oil, coolant mist, and non-corrosive liquids.
Surface-mount the switch using two 0.2-inch mounting holes on a 41 mm horizontal center-to-center spacing. No boot is included, so if the application requires a sealed actuator boot, order one separately. The operating range spans -13 °F to 158 °F, covering most indoor and sheltered outdoor installations.
