E3JK-TR12-C 2M - Omron Through Beam Sensor

Omron is a global leader in industrial automation and sensing solutions, widely trusted by engineering teams and OEMs across India. The brand is known for producing sensors that are rugged, precise, and easy to maintain on the factory floor. From machine builders to plant engineers, Omron products are preferred for their build quality, fast response, and simplified installation. The E3JK series is among the most installed families in industrial setups due to its wide operating voltage and dependable relay output options.

The E3JK-TR12-C 2M is a through-beam sensor system consisting of an emitter (E3JK-TR12-L 2M) and a receiver (E3JK-TR12-D 2M) with a sensing range of up to 5 meters. It uses a 624 nm red LED to ensure visible beam alignment during installation. The sensor supports both 24–240 VDC and 24–240 VAC input, making it suitable for legacy and modern control panels. The relay output supports both Light-ON and Dark-ON modes, and the one-turn sensitivity adjuster allows precise fine-tuning. With IP64 protection, robust ABS housing, and resistance to vibration and humidity, the sensor is ready for harsh factory environments.

The Omron E3JK-TR12-C 2M is widely used in packaging lines, material handling conveyors, machine safety checks, and automated gate systems. Its 5-meter range allows detection of objects across longer distances without false triggering. Technicians can install the emitter and receiver units quickly using the pre-wired 2-meter cables. Its relay output allows direct control of contactors or signaling units without needing a separate interface. With quick setup and Omron’s trusted durability, this sensor reduces downtime while improving production accuracy. Learn more from the official product page: Omron E3JK-TR12-C 2M Specification.
