The Omron E3FA-BN21 Photoelectric Sensor from Omron Corporation is a retro-reflective model designed for transparent object detection with P-opaquing function. It features a 100 to 500 mm sensing distance when used with the E39-RP1 reflector, a red LED light source, and an NPN open collector output. Operating on a 10 to 30 VDC power supply, it includes an M12 connector for secure installation. Belonging to the Omron E3FA Series, this sensor is engineered for dependable performance in industrial automation environments across India.
Used widely in material handling and factory automation, this sensor delivers stable detection in conveyor systems, packaging machinery, and bottling lines. The retro-reflective sensing method allows accurate detection of transparent or reflective materials such as glass or PET bottles. Its IP67 and IP69K protection ensures long-term durability in washdown and dusty environments, making it suitable for demanding industrial applications where reliability and precision are required.
The Omron E3FA-BN21 Photoelectric Sensor supports reliable transparent detection within the E3FA Series. For users needing a PNP output variation with identical sensing capability, the Omron E3FA-BP21 Photoelectric Sensor provides similar specifications but with a different transistor output type. For setups requiring a pre-wired version instead of a connector, the Omron E3FA-BN11 2M Photoelectric Sensor offers a 2-meter pre-wired cable. Alternatively, the Omron E3FA-DN21 Photoelectric Sensor is a diffuse-reflective type for shorter-range sensing at 100 mm, ideal when background reflection needs to be minimized.
The Omron E3FA-BN21 Photoelectric Sensor combines dependable detection performance and solid environmental resistance for consistent operation. With its single-turn sensitivity adjuster, users can fine-tune response to match application needs. Designed within the E3FA Series, it represents Omronβs commitment to durable, industry-focused sensing solutions that maintain performance across temperature variations from β25Β°C to 55Β°C. Industrial users trust Omron for delivering sensors that enhance system stability and reduce maintenance downtime in automated production systems.
