The Omron E3JK-RR12-C 2M Photoelectric Sensor is a retro-reflective type sensor from the well-known Omron E3JK Series. It uses a Red LED (624 nm) as its light source and operates within a 24 to 240 V AC/DC range. This model provides a Relay output and a detection distance of up to 10 meters when paired with the E39-R2 reflector. Built for industrial automation in India, it ensures dependable object detection in demanding environments.
Engineers prefer the Omron E3JK-RR12-C 2M for precise detection in conveyors, automated sorting, and packaging lines. Its Mutual Interference Prevention (MSR) function and Light-ON/Dark-ON operation modes allow stable sensing performance even in complex setups. With its one-turn sensitivity adjustment, users can easily fine-tune detection levels for different materials and surface conditions.
This sensor supports applications in production lines, robotic workstations, and assembly processes where reliable sensing accuracy is essential. Its IP64-rated ABS body offers resistance to dust and moisture, while the 2-meter pre-wired cable ensures flexible installation. The wide operating temperature range of −25°C to 55°C makes it suitable for both indoor and semi-outdoor industrial environments.
The Omron E3JK-RR12-C 2M Photoelectric Sensor is a versatile retro-reflective type sensor equipped with an MSR (Mutual Interference Prevention) function, offering a reliable sensing distance from 100 mm to 6 m when using the E39-R1 reflector or up to 10 m with the E39-R2. For similar functionality without the MSR feature, the Omron E3JK-RR11-C 2M Photoelectric Sensor provides an extended sensing range up to 11 m. If a model without a reflector is preferred, the Omron E3JK-RR12 2M Photoelectric Sensor maintains the same sensing capability but excludes the reflector accessory. Meanwhile, the Omron E3JK-RR13-C 2M Photoelectric Sensor features an infrared LED for environments where red light might cause interference. The E3JK-RR12-C 2M model combines flexible AC/DC power compatibility, relay output, and pre-wired 2 m cable, making it an excellent choice for reliable detection in industrial automation setups.
In summary, the Omron E3JK-RR12-C 2M Photoelectric Sensor stands as a robust industrial automation component within the Omron E3JK Series. It offers consistent performance through its wide voltage range, durable design, and dependable relay output. This combination of durability and flexibility makes it a trusted choice for industries that require reliable sensing over long distances.
