It runs on 10–30 VDC and sinks up to 100 mA, enough to drive a PLC input directly. The red LED emitter makes alignment visible during commissioning, and the light-ON / dark-ON selectable switching covers both presence and gap detection. ## Where it lands Standard fit for part-present detection on conveyors, packaging machines, and automated assembly stations. The 100 mm range works well for close-in object sensing where background suppression isn't critical. IP67 and IP69K ratings let it survive high-pressure washdown cycles, so it belongs in food, beverage, and washdown zones where earlier sensors like old E3Z types would fail. ## How it compares to an older diffuse-reflective sibling The E3ZL812MOMS is the closest functional peer but has a 1 ms response time versus 500 µs. The E3FB offers a 100 mm range, wider 10–30 VDC supply, and M12 connector instead of a 2 m cable.","metaTitle":"Omron E3FBDP21OMI Diffuse Reflective Sensor, PNP 100mm M12","metaDescription":"Omron E3FBDP21OMI photoelectric sensor, diffuse reflective, 100 mm range, 500 µs response, PNP output, M12 connector, IP67/IP69K.
