Ratings that drive the fit
The XS108B3NBM8: Operating voltage spans 12 to 24 VDC, so the sensor drops directly onto a standard 24 VDC sensor power rail or the lower tap of a 24 V supply without an inline regulator. The NPN normally-closed output configuration sinks up to 200 mA, which is comfortably above what most PLC and safety-relay input cards demand and leaves margin for indicator wiring on the same output leg. Switching frequency is rated at 2500 Hz, the figure that matters when the sensor is watching a high-count rotary or a fast conveyor latch event — the target has to clear the 2.5 mm window faster than that cycle rate, or pulses will be lost. The sensing distance is 2.5 mm at flush mounting, meaning the sensor can be embedded in mild steel without a shielded-free derate, which keeps bracket design simple on small fixtures.
Environmental envelope
The enclosure rating of IP65/67 supports washdown and outdoor panel-side exposure as long as the M8 connector face is mated to a rated cordset, and the operating temperature span of -13 to 158 °F covers most factory floors, cold-storage lines, and rooftop equipment cabinets without derate. The threaded M8 barrel with a PPS sensing face is the standard fit on Telemecanique-branded mounting brackets, which keeps retrofitting a worn unit to an existing fixture a direct swap rather than a layout rework.
Approvals and identifiers
The unit carries UL, CSA, and CE approvals, and is identified by UPC 78590164113 (12-digit 389119036170) — enough to walk it through a North American panel shop submittal and a CE-marked European build without a special exemption. The product description in the channel files the device as a Telemecanique XS108B3NBM8 inductive sensor under the Square D Co. manufacturer brand, which is the legacy Square D / Telemecanique branding carried through current distribution.
