The Omron E3JK-TR12-C 2M Photoelectric Sensor is a through-beam detection sensor designed for precision sensing across industrial automation environments. It operates with a 5 m sensing range and supports a 24 to 240 V AC/DC supply, making it suitable for flexible installation in mixed-voltage systems. With a relay output and IP64 protection rating, this model ensures durability and reliable performance in dusty or humid plant conditions. Belonging to the E3JK Series, it continues Omronβs trusted design philosophy for consistent and repeatable detection in production environments.
This sensor uses a Red LED (624 nm) as its light source, ensuring stable signal transmission between emitter and receiver pairs. The E3JK-TR12-C 2M model includes both emitter (E3JK-TR12-L 2M) and receiver (E3JK-TR12-D 2M) units. The sensor offers Light-ON and Dark-ON operation modes for flexible logic control in automation panels. Its one-turn sensitivity adjuster helps technicians quickly fine-tune detection according to the surface reflectivity of materials or distance variations in setup.
In industrial applications, the Omron E3JK-TR12-C 2M is commonly used in conveyors, packaging lines, and automated assembly systems. Its long sensing range makes it ideal for detecting large objects or transparent materials over greater distances. The stable relay output allows integration with PLCs, contactors, or safety relays without requiring signal converters. This capability is valuable for production environments where electrical noise or variable supply conditions exist.
Engineers rely on this model because it minimizes false triggers even under bright ambient light, up to 11,000 lx sunlight. Its rugged ABS housing and environmental tolerance between β25Β°C to 55Β°C enable dependable operation in factories, warehouses, and outdoor machinery setups. The sensorβs quick installation and pre-wired 2-meter cable also reduce maintenance downtime.
The Omron E3JK-TR12-C 2M Photoelectric Sensor is a through-beam type sensor featuring a 5 m sensing distance, red LED light source, relay output, and selectable AC/DC power supply with a 2 m pre-wired cable and mounting bracket. For extended distance detection up to 40 m, the Omron E3JK-TR11-C 2M Photoelectric Sensor provides superior range with a similar AC/DC selectable relay configuration. If you require infrared light for stable operation in dusty environments, the Omron E3JK-TR13-C 2M Photoelectric Sensor uses an infrared LED while maintaining the same 40 m sensing capability. Additionally, the Omron E3JK-TR12 2M Photoelectric Sensor offers the same 5 m sensing distance and red LED detection but comes without a mounting bracket. The Omron E3JK-TR12-C 2M model ensures precise object detection across conveyor and packaging systems, making it ideal for applications demanding accurate long-range alignment and easy installation with reliable AC/DC performance.
In summary, the Omron E3JK-TR12-C 2M Photoelectric Sensor is a robust, high-precision component for industrial automation systems requiring accurate object detection over a 5 m range. With a 24β240 V AC/DC input, relay output, and IP64 rating, it delivers the reliability expected from Omronβs E3JK Series. This model is a dependable choice for factories seeking consistent sensing performance in demanding automation environments.
