The XCKJ161D is a Series XCKJ limit switch with a plunger actuator and a 1NO/1NC contact block rated 4 A at 240 V AC and DC. That 4 A continuous rating at 240 V covers most pilot-duty and control-circuit loads in industrial panels — solenoids, contactor coils, indicator lamps. The IP66 rating means the switch body and the plunger seal withstand direct hose-down and high-pressure washdown, so it fits on packaging lines, food processing equipment, or any area where the enclosure sees water jets. The M12 connector (5-pin) simplifies field replacement: unplug the old switch, plug in the new one, no terminal block rewiring. That saves shift time during a line-down event.
Surface-mount with four 0.21 in diameter holes on a 60 mm vertical by 30 mm horizontal center-to-center pattern. The body footprint is 1.57 in wide by 1.73 in deep by 4.01 in tall (with plunger). The M12 connector accepts standard 5-pin cordsets; no boot is included, so if the application sees continuous immersion or caustic washdown, add a sealed M12 cap or a boot separately. The plunger travel is linear, 0.28 in actuator length, top-mounted. Operating temperature range -13 °F to 158 °F (-25 °C to 70 °C).
