The Omron E3JK-RP12 2M Photoelectric Sensor operates on 10–30 VDC and provides a 6–10 m sensing range using a red LED light source. It belongs to the Omron E3JK Series and is designed for consistent detection performance in industrial automation environments. With a PNP output configuration and IP64 protection, it ensures dependable operation even in dusty or humid conditions. This model is suitable for systems requiring reliable light ON/dark ON selection and fast 1 ms response time.
The sensor is commonly used in conveyor lines, packaging machinery, and automated material handling setups. It helps detect object presence, position, or passage accurately over long sensing distances. The retro-reflective MSR function minimizes interference from shiny surfaces, improving performance consistency. Its pre-wired 2 m cable simplifies installation and reduces wiring errors in machine assembly. Engineers prefer it for its stability, durability, and ease of integration with PLCs or control panels.
The Omron E3JK-RP12 2M Photoelectric Sensor is a retro-reflective DC-powered sensor featuring an MSR function, PNP output, and a reliable sensing range of 100 mm to 6 m when paired with the E39-R1 reflector. For setups needing a relay output and a shorter 4 m detection range, the Omron E3JK-R4M1 Photoelectric Sensor provides stable retro-reflective sensing using a red LED and Light-ON operation mode. If MSR functionality is not required, the Omron E3JK-RP13 2M Photoelectric Sensor offers a slightly extended sensing range up to 7 m with an infrared LED. For users preferring relay output and flexible AC/DC power options, the Omron E3JK-RR12 2M Photoelectric Sensor ensures versatile performance with a sensing distance up to 10 m using the E39-R2 reflector.
In automated assembly systems or logistics conveyors, the Omron E3JK-RP12 2M Photoelectric Sensor helps maintain production efficiency and safety. It performs reliably across an ambient temperature range of −25 °C to 55 °C and resists shock and vibration as specified by IEC standards. Its ABS housing and protective circuits safeguard against short circuits and reverse polarity. Overall, it is a trusted sensor choice under the Omron E3JK Series for industrial automation setups across India.
