Compact photoelectric sensors

Omron launched E3AS Series Reflective-Type Photoelectric Sensors that combine accurate detection for diverse targets, good sensing distance, environmental robustness, and compact size. These sensors are designed to help manufacturers manage varied and flexible production needs more effectively. By maintaining stable detection without being influenced by varying sensing distances, colors, materials, or surfaces, the E3AS sensors make selection, adjustment, and maintenance tasks easier than ever, improving commissioning and operation rates.

High stability and less need of maintenance

The E3AS family’s sensing distance of 1,500 mm is five times longer than that of previous models, and the full sensing range of 50 to 1,500 mm eliminates the need for manufacturers to select different sensors for each application. The time-of-flight (TOF) detection method ensures high detection stability regardless of the characteristics of target objects, making sensor selection and adjustment easier than ever.

In addition, the use of an antifouling coating on the sensing surface reduces false detection and minimizes maintenance needs in environments with oil, dust, or steam. Dirty sensing surfaces can result in false detections when conventional photoelectric sensors are used, causing unexpected recovery work after line stoppages and periodic cleanings to prevent future stoppages.
