The Omron E3JK-RN11 2M Photoelectric Sensor is a retro-reflective sensor from the trusted Omron E3JK Series. It features a sensing range of 100 mm to 11 m using the E39-R2 reflector, and operates efficiently with a 10–30 VDC power supply. Designed with an NPN output configuration, this sensor ensures stable detection performance in automation systems. The housing is made of durable ABS material, and the IP64-rated protection allows reliable operation in dusty and humid industrial environments. This model is suitable for a wide range of industrial automation setups in India.
The Omron E3JK-RN11 2M Photoelectric Sensor is mainly used in conveyor systems, automated packaging lines, and robotic assembly stations. Its retro-reflective sensing method allows easy installation where space or mounting limitations exist. The sensor’s 1 ms response time and stable operation under variable light conditions make it highly efficient for detecting objects on moving lines. The adjustable sensitivity helps users fine-tune performance for materials with different surface colors or finishes. It is a dependable choice for object presence detection, position control, and counting applications in manufacturing plants.
With its precise detection capability and consistent output, the Omron E3JK-RN11 2M supports industrial safety and process accuracy. The 2-meter pre-wired cable design ensures easy connection with PLCs or controllers, minimizing wiring complexity. Its protection circuits—such as power supply reverse polarity and short-circuit protection—enhance operational safety. The sensor’s broad operating temperature range from −25°C to 55°C supports continuous use in demanding environments. This reinforces Omron’s reputation for reliability in photoelectric sensing solutions.
The Omron E3JK-RN11 2M Photoelectric Sensor is a retro-reflective DC-powered sensor offering an NPN output and a wide sensing range from 100 mm to 7 m when used with the E39-R1 reflector. Ideal for reliable object detection without MSR (Mutual Interference Suppression) functionality, it ensures stable operation in industrial automation systems. For users needing the same configuration with MSR, the Omron E3JK-RN12 2M Photoelectric Sensor provides a slightly shorter 6 m range for enhanced interference resistance. The Omron E3JK-RN13 2M Photoelectric Sensor offers the same 7 m detection distance but uses an infrared LED for better performance in dusty or ambient light conditions. Alternatively, for users preferring PNP output with longer 10 m retro-reflective sensing using the E39-R2 reflector, the Omron E3JK-RP12 2M Photoelectric Sensor is an excellent choice for extended-range and flexible wiring applications.
In summary, the Omron E3JK-RN11 2M Photoelectric Sensor is a high-quality retro-reflective model within the Omron E3JK Series, tailored for diverse industrial automation applications. With a 10–30 VDC power supply, NPN output, and up to 11 m sensing range, it ensures dependable object detection and stable operation. Its robust ABS construction and IP64 protection make it ideal for industries seeking long-term, low-maintenance sensing performance.
