Omron E2ES04SR8CJB103MOMS is an M4 inductive proximity sensor from the E2E series, flush-mountable in stainless steel housing. Key ratings: 800 µm sensing distance at 5 kHz switching frequency, PNP normally-open output. Body measures just 4 × 4 × 27.1 mm, with a 300 mm cable terminated in an M8 plug. Rated for 10–30 VDC, draws 10 mA (load current 50 mA). IP67 protection.
Peer comparison: E2BS08KS02MCB120OMS
The E2BS08KS02MCB120OMS is a larger M8 flush-mount sensor (13 mm body) with 2 mm sensing range and 1.5 kHz switching. PNP NO output same, but the connector is M8 3-pin vs cable with M8 plug on this part. Not a mechanical swap – the M4 body requires a 4 mm bore, while the M8 needs an 8 mm hole. Sourcing for a panel designed around the E2B unit? This E2E M4 will not fit without re-drilling and re-terminating.
Installation notes
Flush mount in metal; the sensing face must be flush to avoid reducing the 800 µm range. Operating temperature range is -25°C to +70°C.
