The Omron E3FBDN22OMI is a diffuse reflective photoelectric sensor using a red LED to detect objects up to 300 mm away by sensing reflected light from the target surface itself — no reflector needed. Output is NPN, switching up to 100 mA, with selectable Light-ON or Dark-ON operation. Response time is 500 µs, which handles moderate-speed part detection on conveyors or packaging machinery. The M12 4-pin connector and dual rating IP67/IP69K mean it holds up in washdown zones and dusty environments without an external enclosure. Operating temperature range -25 to 55 °C, powered from 10–30 VDC.

Frequently asked questions
What is the length of the E3FBDN22OMI?
The sensor body length is 48 mm.
What series does the E3FBDN22OMI belong to?
It is part of the Omron E3FB series.
Will the E3FBDN22OMI drop into a panel wired for the E3SDBP21TOMS?
No. The E3FBDN22OMI requires a diffuse target (no reflector) and uses NNP output, while the E3SDBP21TOMS needs a retro-reflector and uses PNP. The wiring and mounting setup are different.
