What it is
The E2AS12KN08M1B1OMS: M12 inductive sensor in the E2A series, non-flush mount, with a stainless steel housing and 8 mm sensing distance. NO output rated 200 mA over 10–32 VDC. Connector is M12, 4-pin. Environmentally rated IP67 and IP69K, so it handles high-pressure washdown. Operating temperature spans -40 to 70 °C. Current draw under 10 mA.
Comparing with the flush-mount sibling
The closest functional peer in the same M12 form factor is the E2AM12KS04M1B14OMS. That part is flush mount with brass housing and 4 mm sensing range. E2AS12KN08M1B1OMS is non-flush, stainless steel, and reaches 8 mm — double the sensing distance. Same connector, same voltage and load ratings, same connector pinout. But the mounting style difference is decisive: non-flush requires more free space around the sensor face, so it won't drop into a panel drilled for a flush mount without repositioning the target or the bracket.
