Pepperl+Fuchs, Twinsburg, OH, has introduced the ML7 Background Suppression (BGS) photoelectric sensors that feature a 31 x 11 x 23 mm housing, and a sensing range of up to 350 mm. Background suppression optimizes the detection of variously colored targets without the need for reflectors or thru-beam sensing arrangements. Objects in the background, even directly behind the target, are ignored. The sensors feature automatic cross-talk protection that enables multiple sensors to be mounted side-by-side with no interference. LED indicators provide power and output status, as well as diagnostic information. The sensors also feature 4-in-1™ output technology that automatically detects the connected load, and sinks or sources as needed. The ML7 BGS sensors have an adjustable sensing range that can be customized. Applications include converting, material handling, packaging, and assembly operations that require long sensing ranges.
