SU17 Series has a push-button teach mode and includes a digital display indicating incoming light level, adjustment steps and scanning conditions. Three sensitivity settings help to meet specific application needs, built-in autotuning for simplified operation and a 10 mm profile for tight spaces. These amplifiers are DIN rail-mountable and capable of providing simple target detection to advanced contrast sensing. Other features include mutual interference protection to minimize sensor cross talk, easy attachment with snap action lever, built-in timer functions, a range of glass and plastic fibers, light on/dark on selectable, NPN and PNP models, and cabled and pigtail quick disconnect models.
