The XS4P08PA340 from Telemecanique Sensors is an inductive proximity sensor in the XS4 series, built for tight-access sensing with a shielded M8 threaded body and a 3 mm maximum sensing distance. PNP normally-open output on three wires, prewired with a 2 m bare cable, means it drops straight into a discrete-input PLC card without a pull-up resistor. Runs on 12–24 V DC and includes overload, reverse polarity, and short circuit protection — three features that cut field returns when a line tech wires it backward or a metal chip grounds the face.
Mounting and environment
Body is PPS, rated IP67 with CE, CSA, Ecolab, and UL listing. That means it handles washdown and mild chemicals — Ecolab approval is the flag for food or beverage wash zones. Operating range -13 °F to 158 °F covers indoor panel environments and unheated warehouse lines. Shielded face means it can be mounted flush in steel without derating the 3 mm sensing distance. M8 threaded barrel fits standard bracket runs; the 33 mm overall height leaves room in tight clusters.
Sourcing note
Current production part — no last-time-buy panic, no hunting surplus. Fast on the RFQ, easy to slot into a BOM line. If you've got a pallet of these coming through, the protection features mean fewer duds to sort out. Value's in the sort, and this one's a clean pick.
