What this sensor is, and where it lands
The Square D XUB1BNAWM12 is an XUB-series tubular retroreflective photoelectric sensor in an 18 mm threaded barrel, designed for object detection against a reflector rather than a separate emitter/receiver pair. It carries an infrared sensing beam and reads the return off a reflector at a working distance of 4 m, with the optical window oriented 90° to the side of the barrel so the cable exits cleanly along the mounting rail. Nickel-plated brass construction and a NEMA 4X/12, IP67 sealed housing let it survive washdown and most factory atmospheres, with an operating temperature range of -13 to 131 °F covering cold storage and typical process-line heat.
Electrical interface and switching behavior
Power is 12 to 24 VDC across three wires, with a 4-pin micro connector on the barrel — supply common on one pin, load switched through the NPN output on the third. Output configuration is NPN, normally open, rated for 100 mA load current — the sinking-output topology that most Japanese and European PLC digital inputs expect. Response time is 1 ms on/off, and the listed operating frequency is 500 Hz, which is the figure that governs high-speed counting and small-part detection on conveyors rather than the headline 4 m range. A yellow LED indicator marks output state, simplifying alignment during commissioning and giving the maintenance tech a visual fault-isolation point without pulling the wiring diagram.
Approvals and compliance footprint
The XUB1BNAWM12 carries UL, CSA, and CE approvals, which clears it for installation in panels bound for North American and European machinery. Lifecycle stage is listed as current, so the part remains a live BOM line and is specified to order against an RFQ rather than routed through last-time-buy channels. The product carries a California Proposition 65 warning for diisononyl phthalate (DINP) and di-isodecyl phthalate (DIDP); this is a chemical-exposure disclosure rather than a use restriction, but it belongs in the decl pack for food, beverage, and pharmaceutical sites that flow documentation through quality.
Sourcing posture
Quoted to order against an RFQ for panel builders and field-service buyers who need a confirmed shipment date rather than a marketplace listing; the part is current production and the lead profile is governed by factory allocation, not a last-time-buy window.
