The E Series is designed for sensing applications where there is virtually no room for mounting a sensor. Even with an ultra-small 20 mm H × 12 mm W profile, the E Series offers long sensing distance of 500 mm. An LED light source provides a highly visible beam spot and is a great help in sensor alignment. The sensors are available in two mounting styles: the front-sensing style sensors, which are 3.5-mm thick, and the side-sensing styles, which are 5.0-mm thick. They require 12 to 24 volt DC input power and are offered in NPN or PNP output types for reliable connection to any PC, PLC, and relay input device. Bright dual LED indicators display power and output status for easy monitoring.
