The Omron E3JK-DR12-C 2M Photoelectric Sensor is a diffuse-reflective type sensor designed for accurate object detection in factory environments. It operates on a wide voltage range of 24 to 240 VDC/AC and delivers reliable switching through its relay output. The device provides a 300 mm sensing distance using a red LED light source and features IP64 protection for durability against dust and moisture. This model belongs to the trusted E3JK Series and is widely used in industrial automation systems where consistent optical sensing is essential.
In practical applications, the Omron E3JK-DR12-C 2M Sensor is often used for position detection, product counting, and part alignment tasks. Industries such as packaging, conveyor automation, and assembly processes benefit from its fast response time of 20 ms and one-turn sensitivity adjustment. Its diffuse-reflective sensing allows detection without requiring an external reflector, making it suitable for confined or complex installation setups. By ensuring stable performance in variable lighting and temperature conditions, this sensor helps reduce downtime and improve production efficiency.
The rugged construction of this Omron Photoelectric Sensor, with an ABS housing and secure pre-wired 2M cable connection, supports long-term use in challenging industrial environments. It resists ambient illumination up to 11,000 lux and operates effectively in temperatures from −25°C to 55°C. These characteristics make the E3JK-DR12-C 2M ideal for continuous operation in automated lines where reliability and endurance are vital.
The Omron E3JK-DR12-C 2M Photoelectric Sensor is a diffuse-reflective type sensor offering a 300 mm sensing distance with a red LED light source. It supports both AC/DC power supply options, features a relay output, and comes pre-wired with a 2 m cable and mounting bracket for easy installation. For users needing a longer detection range, the Omron E3JK-DR11-C 2M Photoelectric Sensor provides a 2.5 m sensing distance while maintaining the same red LED and relay output. If an infrared light source is preferred, the Omron E3JK-DR13-C 2M Photoelectric Sensor delivers identical 2.5 m sensing capability using an infrared LED. Alternatively, the Omron E3JK-DR14-C 2M Photoelectric Sensor combines the shorter 300 mm sensing range with an infrared LED, ideal for environments requiring reduced optical interference.
In summary, the Omron E3JK-DR12-C 2M Photoelectric Sensor delivers stable and precise detection for industrial automation applications across India.
