Omron E3ZLS66 Photoelectric Sensor NPN, 200 mm Sensing Distance, Background Fade-Out

Omron E3ZLS66 is a diffuse-reflective photoelectric sensor with background fade-out (triangulation), NPN output, and a sensing range adjustable from 20 to 200 mm. Electrical connection is via M8 connector on a 3-wire DC supply, with 100 mA maximum output current and manual sensitivity adjustment. The 10.8 by 31 by 20 mm cuboid housing includes light/dark switching, a normally-open contact function, and one signalling output; no communication interface is fitted. A mounting bracket is required for installation.
