The Omron E3FA-BP22 Photoelectric Sensor is a retro-reflective type device with transparent object detection using the P-opaquing function. It features a sensing distance of 0.1 to 2 m when used with the E39-RP1 reflector and operates on a 10 to 30 VDC power supply. With a PNP open collector output and durable plastic M18 cylindrical housing, this sensor belongs to the Omron E3FA Series, engineered for reliable performance in industrial automation systems. It is suitable for harsh production conditions, ensuring consistent and precise object detection.
Used widely in industrial automation, this sensor is ideal for conveyor lines, packaging systems, and assembly processes. It delivers accurate detection of transparent materials such as bottles, films, and containers without misreadings. The short response time of 0.5 ms enables quick operation, ensuring precise synchronization with moving equipment. Its IP67 and IP69K protection ratings allow installation in dusty or high-pressure washdown environments, maintaining operational reliability and reducing maintenance needs across automated setups.
The Omron E3FA-BP22 Photoelectric Sensor offers PNP output and M12 connector configuration for flexible installation. For similar transparent detection with NPN output, the Omron E3FA-BN22 Photoelectric Sensor provides the same sensing range but supports NPN wiring compatibility. Users needing a pre-wired version can opt for the Omron E3FA-BP12 2M Photoelectric Sensor, which includes a 2 m cable connection instead of an M12 connector. Alternatively, those requiring longer sensing up to 4 m can choose the Omron E3FA-RP21 Photoelectric Sensor, designed for standard retro-reflective detection with the MSR function for enhanced stability.
The Omron E3FA-BP22 Photoelectric Sensor combines compact design, wide voltage tolerance, and reliable object detection for industrial automation. With its robust IP69K housing, polarized red LED light source, and quick response performance, it ensures dependable operation across diverse factory environments. This model reinforces Omron’s reliability in precision sensing technology, offering Indian industries a trusted solution for transparent object detection and machine control integration within automated production systems.
