It emits a red LED beam and detects objects that break the path to a reflector, giving a 4 m sensing range. The PNP output switches up to 100 mA, and the response time is 500 μs, fast enough for most conveyor and packaging applications. The M12 4-pin connector mates to standard cordsets, and the IP67/IP69K ratings mean it handles washdown environments without a secondary housing. Operates on 10–30 VDC. Selectable Light-ON or Dark-ON switching. M12 4-pin connector; 48 mm length.","metaTitle":"Omron E3FBRP21OMI Retro-Reflective Sensor, PNP, 4m, M12","metaDescription":"Omron E3FBRP21OMI retro-reflective photoelectric sensor with 4 m range, PNP output, M12 connector, IP67/IP69K, 100 mA.

However, the sensing method changes: the E3FBRP21OMI is retro-reflective (requires a reflector) with a 4 m range, while the E3FBDP21OMI is diffuse reflective with a 100 mm range. Adjust mounting and target accordingly."},{"question":"What is the closest functional alternative within the same series?","answer":"The E3FBDP21OMI is a same-series sibling but it is a diffuse reflective sensor with a 100 mm sensing distance, not retro-reflective.
