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.
Sourcing and lifecycle
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.
