Omron E3JK-RP11 2M Retro-Reflective Photoelectric Sensor 10-30 VDC PNP Output 7–11 m Cable

The Omron E3JK-RP11 2M is a high-performance photoelectric sensor designed for reliable object detection in industrial automation, material handling, and control systems. This retro-reflective sensor uses a red LED light source and detects objects at long distances when paired with compatible reflectors — up to approximately 7 m using an E39-R1 reflector and up to 11 m with an E39-R2 reflector (reflector sold separately).

Featuring a PNP open-collector output, this sensor supports selectable Light-ON and Dark-ON operation modes for flexible system integration. The robust design with IP64 protection and pre-wired 2 m cable provides durability in industrial environments, while the compact ABS housing enables easy installation in control panels and machinery.
