Response time is 500 µs, so it catches objects moving past at line speeds up to about 2 m/s without the PLC input missing the edge — fast enough for most packaging and material-handling pick cycles. Output is NPN, light-ON or dark-ON selectable via the wiring — common in Asian-origin panels and older North American PLC input cards that sink to common. ## M12 termination and IP66 — washdown-ready, not submersible Termination is a 4-pin M12 connector — mates with standard M12 cordsets, so you can swap the sensor without pulling wire back through the conduit. The IP66 rating means it handles hose-down cleaning and rain, but not continuous immersion; fine for food processing washdown zones and outdoor covered installations. Body length is 34.5 mm — short enough to mount in tight bracket spaces on a pick-and-place arm or inside a machine guard frame. Operates from 10 to 30 VDC over -25 to 55 °C ambient, which covers most indoor industrial environments and unheated warehouses.","metaTitle":"Omron E3F1DP21OMI Diffuse Reflective Sensor, 100 mm, NPN","metaDescription":"Omron E3F1DP21OMI photoelectric sensor, diffuse reflective, 100 mm range, NPN output, M12 connector, IP66.

The mounting hole pattern and barrel diameter may also differ.
