It's a PNP output, light-ON / dark-ON selectable unit, switching in 500 µs. Power supply is 10–30 VDC, output load rated 100 mA. The M12 4-pin connector makes it a quick swap on a line — no hard-wiring. ## Where It Lives Housing is 16.6 mm wide, 45 mm long — the standard E3FA footprint. If your panel already has M12 pigtails cut for this series, it drops right in. IP67 and IP69K protection means it can take washdown cycles; fine for food or beverage lines. The closest functional peer is the E3FADP22OMI — also diffuse, PNP, same housing and connector. The difference is reach: the E3FABP21OMI covers 500 mm compared to 300 mm on the E3FADP22OMI. Both share the 100 mm minimum sensing distance, so if your old bin had the 300 mm part but the application needs more headroom, this is a non-wiring upgrade. The retro-reflective E3FARP21F2OMS goes to 4 m but uses a reflector; that's a different install pass.","metaTitle":"Omron E3FABP21OMI Diffuse Photoelectric Sensor, 500 mm","metaDescription":"Active-production diffuse photoelectric sensor, PNP, 500 mm range, 500 µs response, M12 4-pin, IP67/IP69K.
