The E3AS-HL series complementary metal oxide semiconductor (CMOS) photoelectric sensors provide stable detection even as objects vary. The series is equipped with sensing technology that reduces the influence of color patterns, glossiness and shape to allow for reliable detection amid changing production requirements and has an option to use either a line beam or a spot beam model. A simple teaching mechanism makes setup quick and easy. Operators can complete the setup process by pressing the teach button, while the OLED display provides visible and clear status information. With IO-Link, the series can communicate distance values in millimeters and be taught remotely to set detection thresholds.
