The Omron E3FB-LP22 Photoelectric Sensor belongs to the Omron E3FB Series and is designed for reliable detection in industrial automation systems. It features background suppression (BGS), 200 mm adjustable sensing distance, and a red LED light source. Operating on a 10 to 30 VDC power supply with a PNP open collector output, this metal-bodied sensor uses an M12 connector for quick installation. Its IP67 and IP69K protection ensures durability against dust, water, and high-pressure washdowns, making it ideal for demanding factory environments.
Widely applied in automated conveyor lines, packaging equipment, and material handling systems, this model provides stable and precise object detection. Its fast 0.5 ms response time enables accurate presence sensing even on high-speed production lines. The metal M18 cylindrical housing enhances robustness, while the single-turn sensitivity adjuster allows quick setup during equipment calibration or maintenance. These attributes make it a dependable choice for continuous industrial operations.
The Omron E3FB-LP22 Photoelectric Sensor provides reliable background suppression sensing within compact machinery setups. For configurations requiring similar functionality with different wiring or output types, the Omron E3FB-LN22 Photoelectric Sensor offers an NPN output using the same M12 connector. The Omron E3FB-LP12 2M Photoelectric Sensor provides PNP output with a 2 m pre-wired cable instead of a connector. Alternatively, the Omron E3FB-LN12 2M Photoelectric Sensor features NPN output and pre-wired configuration, suitable for compact control panels or limited-space installations. Each variation maintains the same 200 mm BGS sensing capability while differing in connectivity and signal output options, helping engineers select the right model for their specific automation requirements.
The Omron E3FB-LP22 Photoelectric Sensor reinforces the brand’s focus on robust and consistent sensing solutions for industrial applications. With its metal housing, 200 mm BGS detection, and IP69K-rated protection, it delivers dependable performance in harsh factory conditions. Omron’s proven reliability ensures long operational life and reduced downtime in assembly lines, robotic systems, and automated packaging setups. The E3FB-LP22 model represents a precise and stable sensor choice trusted across India’s industrial automation sectors.
