The Square D XUX5APBNM12 is a diffuse proximity photoelectric sensor with a 2.1 m sensing range, PNP NC 3-wire output rated for 100 mA at 12 to 24 VDC. Response time is 2 ms with adjustable on/off delay, and the solid-state output switches at up to 250 Hz. Enclosure rating is IP67 and NEMA 1/3/4/13, suited for washdown and dusty environments. The PBT body and 4-pin micro DC (M12) connector are standard for this class. Approvals include UL, CSA, and CE.
In a noisy plant, check the shield integrity on the M12 cable — the sensor itself will give a clean signal if the ground path is solid.
