What this sensor is and how it wires in
The Square D (Telemecanique) XS908R4PAM12 is an OsiSense XS tubular inductive proximity sensor in an 8 mm threaded 303 stainless-steel barrel with a stainless sensing face, terminated on a 4-pin M12 male connector and built to IP67/69K. It runs on 12 to 24 VDC as a 3-wire device and switches a PNP normally-open output rated for 200 mA load current, with a 700 Hz switching frequency — that's the input the panel wireman lands on the M12 pigtail and the figure the PLC input card has to sink cleanly on each cycle. Sensing is front-face only at a 6 mm nominal distance, and the sensor is ferrous-metal selective — so it ignores non-ferrous targets like aluminum or brass shavings and only fires on steel, which is the right call for stamping-cell and weld-fixture detection where aluminum flash would otherwise nuisance-trigger.
Environmental envelope and approvals
Operating temperature spans -13 to 158 °F, so the head sits fine in an unheated cabinet or near a warm hydraulic manifold; pair it with an M12 cordset rated for the same ambient and the install is straightforward. IP67/69K on a 303 stainless body and face is the washdown-grade combination — pressure-jet cleaning and chemical sanitizing won't end the sensor's life the way they'd kill a nickel-plated brass barrel. Approvals on record are UL (Canada and US) and CE, matching the listed compliance marks for this order code.
The listed UPC is 78590144768 (12-digit 389119079085), which is the clean cross-reference for parallel-import reconciliation against factory cartons and a useful cross-check when a shipment arrives short-packed. California Proposition 65 warning applies: the product can expose users to DINP and DIDP — that line has to ride along on packing paperwork and dealer disclosures for sale into California, no exceptions.
Storeroom view — keeping the SKU on the shelf
For the MRO keeper, this is one SKU: 8 mm threaded body, M12 connector, PNP NO, ferrous-selective. No special variant, no exotic cable — that's a clean cross to any other OsiSense XS 8 mm M12 PNP NO ferrous sensor in the family, and that's another SKU consolidation if the alternate form factor ever lands in the same bin. Spare planning: the 6 mm sensing distance and 200 mA output pair it with standard M12 patch cords, and the front-face orientation means a replacement drops into the same bracket without re-aligning the target.
