Product Overview

The Omron E3JK-DR12-C is a high-performance diffuse reflective photoelectric sensor designed for industrial detection applications. This sensor offers an impressive 8 times longer detection distance compared to previous models, with a maximum sensing range of 2.5 meters for diffuse reflective detection. The E3JK-DR12-C features a visible red LED light source that provides excellent beam visibility for easy alignment during installation. The sensor utilizes a compact rectangular housing measuring 48x24mm, making it suitable for installations in space-constrained areas. With its DC relay output, this sensor can directly switch loads up to 3A, eliminating the need for external relays in many applications. The sensor operates on a wide voltage range of 12-240 VDC or 24-240 VAC, providing flexibility for various power supply configurations. The E3JK series is known for its reliability in harsh industrial environments, featuring excellent resistance to ambient light interference and stable detection performance regardless of target color or surface finish. This sensor is ideal for packaging lines, material handling systems, and general object detection in manufacturing processes.

FAQ for E3JK-DR12-C

What is the difference between diffuse and retroreflective sensors?
Diffuse sensors detect light reflected from the target object itself, while retroreflective sensors detect light reflected from a reflector placed opposite the sensor.
Can the E3JK-DR12-C detect transparent objects?
Diffuse sensors may have difficulty with transparent objects. For transparent object detection, consider retroreflective sensors with MSR function.
What is the sensing distance under optimal conditions?
The E3JK-DR12-C has a maximum sensing distance of 2.5m for diffuse reflective detection with a white paper target.
