Registration-mark sensor

The high-speed, high-resolution Mark-Eye Pro sensor accurately detects printed registration marks on continuous web machinery. The broadband characteristics of a white LED light provides the high resolution needed for detecting a wide range of color combinations on any color background.

Features of the sensor include a 45-µsec response time, easy one-touch Autoset, high immunity to ambient light, five-LED contrast indicator, and selection of lens and fiber-optic light guides.
