The Omron E2BS08LN04MCB1OMI is an M8 inductive proximity sensor from the E2B series, built for non-flush mounting. It detects ferrous targets up to 4 mm away and switches at 1 kHz, with a PNP normally-open output. The stainless steel housing and IP67 rating mean it handles washdown environments on a machine tool or conveyor line — no extra enclosure needed for coolant splash or dust.
The 4 mm sensing distance is the maximum for an M8 non-flush sensor — the unshielded coil projects farther than a flush-mount version of the same size, so you get the full 4 mm without needing to countersink the target. That 1 kHz switching frequency keeps up with fast-pick-and-place cycles or high-speed counting. Supply it between 10 and 30 VDC; the sensor draws 10 mA quiescent and can sink or source 200 mA on the output. Repeat accuracy of 10% means the switch point can drift up to 0.4 mm over temperature and time — fine for presence detection, not for precision positioning. The M8 3-pin connector mates with standard M8 cordsets. Body dimensions are 13 mm square by 66 mm long, so it fits the same 13 mm mounting hole pattern as any M8 tubular sensor. Non-flush mounting requires a free zone around the sensing face — about 8 mm of metal-free space per the standard derating curve — so don't bury it in a steel bracket.
