40 mm unshielded inductive — universal supply, washdown-rated
The XS8C4A4MPN12 is a rectangular inductive proximity sensor from Schneider Electric's XS8 series, offering a 40 mm sensing distance in an unshielded configuration. That 40 mm range is the maximum on mild steel — the correction factor for stainless or aluminum will reduce it, so budget accordingly if your target isn't standard steel. What sets this part apart is the supply flexibility: it runs on anything from 24 V to 240 V, AC or DC. That means one sensor stock number covers both 24 VDC control panels and 120/240 VAC direct-wired lines — no need to carry separate DC and AC variants. The IP65/IP67/IP69K triple rating means the sensor body and the cable entry survive high-pressure hot-water washdown. On a food, beverage, or pharmaceutical line where the sensor sees caustic spray at 80 °C, the IP69K seal keeps the electronics dry. The PBT housing handles the chemical exposure without cracking.
Programmable output — one sensor for NO or NC logic
The output circuit is programmable as NO or NC, configurable at installation. That means the same part number serves both fail-safe (NC for guard monitoring) and standard presence-detection (NO) schemes — the MRO planner can stock one sensor for either role. Rated load current is 300 mA maximum, which directly drives most PLC inputs and small relays without an interposing interface. The two-wire design simplifies wiring — the sensor is in series with the load, so polarity matters on DC but the wide supply range absorbs the voltage drop. Termination is bare wire with screw clamp terminals inside the sensor head — no connector to mate, no cordset to chase. For retrofit into an existing junction box, that's often simpler than finding the right M12 pigtail.
Current lifecycle — approvals for global panels
Approvals include CCC, CE, CSA, and UL Listing — the sensor is accepted in North American, European, and Chinese panels without a separate agency review.
