Signal you can trust when the cabinet is loud
The XS7E1A1PAL2: The output is PNP, make-contact (NO), so the switching line sources current to the PLC input rather than sinking — important on a sinking-input card where an NPN device would never pull low. Proximity sensors in this class are the workhorses of discrete position detection on conveyors, valve actuators, and part-presence checks on assembly cells, and the PNP NO configuration matches the majority of modern PLC input cards.
Electrical budget and switching speed
Power the sensor from 12 V to 24 V and it draws roughly 10 mA, leaving plenty of headroom for the 100 mA load current rating the output can switch directly into a PLC input or a small relay coil. At 1 kHz switching frequency it will keep up with high-speed counting on a conveyor index pulse or a cam-follower position check, but it is not the sensor to pick for a high-resolution encoder duty where multi-kHz edge rates are routine.
Seal, jacket, and the 2 m cable question
Termination is a hardwired 2 m cable, not a quick-disconnect — the gland is the seal, so plan the routing before the bracket is welded, and treat the cable as the wet end of the assembly. The housing is PBT and the unit carries an IP68 rating, which means the body and the cable exit survive full immersion duty on a washdown line, outdoor skids, or anywhere coolant and cutting fluid reach the sensor head.
Panel footprint and stacking
Body dimensions are 26 mm wide by 26 mm long by 13 mm tall — a compact square that drops into the same bracket pattern as the rest of the XS7 flat-pack range and stacks cleanly when several sensors need to ride one fixture.
Where the channel stands and how to pull one
Lifecycle status is recorded as current under the Schneider Electric line, so the part is not on a last-time-buy clock and a BOM commitment carries no near-term obsolescence risk on the manufacturer's side. For buyers holding a spot for an urgent line-down spare or building out a panel run, the practical path is an RFQ against the quantity and configuration needed — current price and lead time are confirmed at quote time, with no need to negotiate a closing-out buy.
