The Omron E2BS08KN04WPB15MOMI is an M8 threaded-barrel inductive proximity sensor from the E2B series, with a PNP normally-open output and a 4 mm sensing distance. The non-flush mounting requirement means the sensing face needs a clearance zone around it — the target metal must approach from the front, not the side — so plan for that standoff when laying out the bracket or fixture. Stainless steel housing (M8 × 42 mm) and IP67 sealing let it live on a washdown line or outdoors without a secondary enclosure; the 5 m pigtail cable runs straight to the control cabinet or junction box.
The 4 mm sensing distance is the rated operating distance (Sn) for a standard target — in practice, derate by about 20 % for real-world materials like mild steel, and more for aluminum or stainless targets. The 1 kHz switching frequency means it can count fast-moving parts on a conveyor or detect passing gear teeth without missing a pulse. PNP NO (normally open) output sources 200 mA at 10–30 VDC, enough to drive a PLC input directly or switch a small relay; the 10 mA current consumption is the sensor's own draw, not the load. Repeat accuracy of 10 % is typical for this class — fine for presence/absence detection, not for precision positioning.
The closest peer in the E2B M8 family is the E2BS08KS02MCB120OMS — same barrel dimensions (13 × 13 × 44 mm), same stainless housing and IP67 rating, same PNP NO output. The key difference: the KS02 variant is flush-mountable (sensing face can be level with the mounting surface) and has a shorter 2 mm sensing distance. The KN04 here is non-flush and reaches 4 mm. If your existing bracket was cut for a flush-mount sensor, the non-flush body will still bolt into the same M8 threaded hole, but you need the extra standoff clearance around the face. No rewiring needed — same pinout, same cable.
