Square D / Telemecanique XUK8AKSNM12 is a compact background-rejection photoelectric sensor from the Osisense XUK family. Runs on 12 to 24 VDC, with a universal NPN/PNP output that saves you carrying two part numbers. Sensing distance is 1 meter, and it fires a clean signal in 2 milliseconds—fast enough for most conveyor registration or part-present checks. The M12 4-pin male connector is the standard on this class—easy to swap without opening the panel. IP65 enclosure means it handles washdown and dust without a secondary housing. Operating temperature from -13 to 131°F covers unheated warehouses and outdoor installs under a shade. Switching frequency is 250 Hz, and maximum load current is 100 mA—plenty for a PLC input or a small relay. Input draw is only 35 mA. PMMA lens material is standard for diffuse/proximity applications; no special cleaning needed.
Runs on 12-24 VDC, compatible with a standard 24 VDC bus. The NPN/PNP output handles both sinking and sourcing inputs; the 100 mA load current drives a small relay. Response time of 2 ms at 250 Hz suits high-speed counting and gap detection. For simple presence detection, the sensor provides ample headroom.
