The Omron E3FB-DN22 Photoelectric Sensor from Omron Corporation is a diffuse-reflective type sensor designed for precise object detection in industrial environments. It offers a 300 mm sensing distance using a red LED light source (624 nm) and operates on a 10 to 30 VDC power supply with NPN open collector output. This model belongs to the Omron E3FB Series and features a metal M18 cylindrical housing with IP67 and IP69K protection, making it ideal for high-pressure washdowns in industrial automation systems.
Widely used in conveyors, packaging, and assembly systems, this photoelectric sensor ensures reliable target detection even under challenging lighting or environmental conditions. The E3FB-DN22 model delivers consistent performance with its 0.5 ms maximum response time and manual sensitivity adjustment for fine-tuning detection. Its nickel-plated brass housing and high ingress protection rating enable long service life in production lines, bottling plants, and automated sorting equipment where stable and repeatable sensing is critical.
The Omron E3FB-DN22 Photoelectric Sensor offers NPN output and an axial metal housing for robust operation. For users needing a PNP output alternative, the Omron E3FB-DP22 Photoelectric Sensor provides the same 300 mm sensing range with identical mechanical design. If a pre-wired configuration is preferred, the Omron E3FB-DN12 2M Photoelectric Sensor includes a 2 m cable instead of an M12 connector. For applications requiring retro-reflective detection with an extended sensing distance of 0.1 to 4 m, the Omron E3FB-RN21 Photoelectric Sensor featuring an MSR function offers reliable operation against reflective interference, suitable for reflective or moving object detection tasks.
The Omron E3FB-DN22 Photoelectric Sensor reinforces Omronβs reputation for dependable sensing components in industrial automation. With a compact metal housing, adjustable sensitivity, and IP69K protection, it performs reliably in wet or dusty factory environments. Supporting 10 to 30 VDC operation and fast response, it enables precise object detection essential for manufacturing efficiency. This modelβs robust design and stable detection performance make it a trusted choice for engineers and automation professionals across Indiaβs industrial sectors.
