It runs on 10–32 VDC, sinks up to 200 mA at 1 kHz switching frequency, and is housed in stainless steel rated IP67/IP69K — meaning it withstands high-pressure washdown in clean-in-place zones. For a procurement decision, the key constraint is the NC logic: the output opens when a target is present, so the safety or control circuit must be wired accordingly. The flush mount allows the sensor to be embedded in metal without derating, and the M12 connector simplifies field replacement — no hardwiring at the sensor head. Peer E2AS12KS04M1B1OMS shares the same sensing distance, voltage, stainless steel, and connector but outputs NO and uses a through-hole barrel. The NC vs NO difference alters fail-safe logic: the PLC input expects a closed signal when the target is absent. If your application requires an 8 mm sensing range or non-flush mounting, consider E2AS12KN08M1B1OMS — but note it is also NO output and non-flush, which demands an air gap around the sensor face to avoid false triggers.","metaTitle":"Omron E2AS12KS04M1B2OMS Inductive Sensor, NC, 4 mm, M12 Conn","metaDescription":"M12 flush-mount inductive proximity sensor, NC output, 4 mm sensing distance, 10–32 VDC, 200 mA load, IP67/IP69K, stainless steel housing.
