The Omron E3FB-DN12 2M Photoelectric Sensor is a metal-bodied, axial Diffuse-reflective sensor from the E3FB Series used in industrial automation. It offers a 300 mm sensing distance, operates on 10 to 30 VDC, and provides IP67/IP69K protection for washdown environments. The sensor has a pre-wired 2 m cable, an M18 metal housing, and a single-turn sensitivity adjuster suitable for assembly- and conveyor-line installations.
Used on conveyors, packaging machines, automated assembly stations and pick-and-place lines, this sensor delivers reliable object detection with stable NPN switching and a fast 0.5 ms response. Its metal housing and high protection rating reduce downtime from contamination and washdown, while the simple sensitivity adjuster speeds commissioning and on-site tuning.
The Omron E3FB-DN12 2M Photoelectric Sensor performs diffuse-reflective detection for short-range presence sensing; related variants address different connection and output needs. The Omron E3FB-DP12 2M Photoelectric Sensor differs by offering a PNP output instead of NPN and otherwise shares the same diffuse 300 mm range, the Omron E3FB-DN22 Photoelectric Sensor differs by providing an M12 connector option rather than a pre-wired cable for streamlined replacement, and the Omron E3FB-RN11 2M Photoelectric Sensor differs by using a retro-reflective MSR method for longer-range detection up to 4 m with a reflector. The Omron E3FB-DN12 2M remains the NPN, pre-wired diffuse-reflective choice for compact short-range sensing.
Built for repeated, reliable operation in industrial settings, the E3FB Series diffuse sensors combine consistent NPN output behavior, a 2 m pre-wired connection and easy sensitivity adjustment for fast integration. The mechanical robustness, IP67/IP69K rating and 10β30 VDC tolerance make this product suitable for factory floors, food-and-beverage washdowns, and machine-mounted detection where uptime and predictable switching are required. Technical buyers can rely on the Omron E3FB-DN12 2M for stable, maintenance-friendly sensing in automation applications.
