Description
The Omron E3FA-RP21 is a compact M18 cylindrical photoelectric sensor featuring a durable plastic housing, designed for reliable object detection in industrial automation. This retro-reflective sensor utilizes a red LED light source and operates on the retro-reflective principle with polarization filter, enabling stable detection of reflective objects while ignoring background interference. With a sensing range of up to 2 meters and a built-in sensitivity potentiometer, it offers flexible adjustment for various applications. The sensor provides a PNP normally open (NO) output configuration and features an M12 4-pin connector for easy installation and wiring.
