What this sensor is and what it does
The Omron E2BM18LN16M1B1OMI is an M18 threaded-cylinder inductive proximity sensor with a 16 mm nominal sensing distance, non-flush mount, PNP normally-open output, and M12 4-pin connector.
Key ratings and what they mean for selection
Sensing distance is 16 mm for a mild steel target. Switching frequency is 400 Hz. Repeat accuracy is 10 %. Non-flush mount means the sensing face must be set back from surrounding metal or a non-metallic window must be provided — a common oversight when replacing a flush-mount sensor in a threaded hole.
How it compares to the E2BS08KS02MCB120OMS
The E2BS08KS02MCB120OMS is an M8 flush-mount sensor with a 2 mm sensing distance and M8 3-pin connector. It is not a panel drop-in replacement: the mounting thread, flush/non-flush behavior, and connector type differ. Use the E2BS08 only when space limits to an 8 mm body and the target gap is under 2 mm.
