The E2B-M18LN10-M1-B1 is an Omron photoelectric sensor that uses a background-suppression sensing method to detect objects. It is an M18 size cylindrical projective retro-reflective sensor with a polarization function. It is used for applications that require highly repeatable, reliable, and consistent object detection. It can detect light and dark objects, with a sensing distance of 10 meters and a sensing range of 3 mm to 500 mm. The sensing range can be adjusted by an external potentiometer. It features a built-in visible LED light and a visible narrow beam visible beam, which makes it easier to inspect objects. This is suitable for applications that demand long sensing ranges, such as detection of large parts and machine automation. Additionally, it offers a high resistance to ambient light and electromagnetic radiation, making it suitable for applications in harsh industrial environments.
