Fiber-Optic Sensors Pick Up All Colors

Claimed to provide powerful, economical, DIN rail-mountable solutions for product sensing and color mark registration control with response times of 0.2 or 0.5 ms and ranges up to 26.3", D11 and D11Expert fiber-optic sensors are totally self-contained visible beam sensors that operate from 10 to 30 vdc. A choice of red, green, or blue LED sources give users a sensing solution for all product sensing or color mark applications to detect colors and low-contrast marks, such as yellow ink on a white background. The visible green LED model optically improves sensing contrast, especially with translucent materials. The D11Expert model offers "teach mode" programming that lets users automatically adjust sensitivity with a pushbutton, and features an alignment indicating device.
