Sensor Detects Marks On Transparent And Translucent Webs

A unique feature of the Mark-Eye color mark registration sensor is its ability to detect color marks on the majority of transparent and translucent materials on a continuous web. This pulse-modulated, photoelectric registration mark sensor is said to be most suitable for use on form, fill and seal machinery. It operates on voltages from 10V to 30V and can detect marks as slight as 0.03125" x 0.25". Other features include ease of setup and adjustment via a single pushbutton and an opacity-sensing mode capable of detecting any color. TRI-TRONICS CO., Tampa, FL. (800) 237-0946.
