SMARTEYE COLORMARK ll Registration Mark Sensors Description
The SMARTEYE COLORMARK ll Registration Mark Sensors combine unique color perception ability with very high speed response. Many important features have been incorporated into the design to meet the increasing demand for precision registration control on today’s higher speed packaging machinery.  It provides extended operating ranges, enhanced background suppression and the elimination of saturation problems.

The specific task of a photoelectric registration mark detector is to respond to printed registration marks on packaging material as they pass through the sensor's light beam. The output of the sensor must switch when the mark arrives precisely in position for the control function to occur. The resolution of the exact location of each passing registration mark is keynote to ensure that the initiation of the electromechanical response triggered by the sensor is in synchronization with the arrival of the mark.

SMARTEYE COLORMARK ll Registration Mark Sensors Features
• Built-in Connectors
• Waterproof Housings
• Clutch Knob Adjustment (Offset/EDR ® )
• Unique 10 LED Contrast Indicator
• Addition of EDR ® "Enhanced Dynamic Range" - eliminates hot spot glare effects. Works on the shiniest materials, including foils.
• Optional Pulse Stretcher guarantees a minimum of 10 milliseconds output- ample time for visual LED verification and for the control to respond.
• Choice of light source – green, red, blue, or white.

SMARTEYE COLORMARK ll Registration Mark Sensors Benefits
• Minimizes downtime
• Flexible and accommodating for a variety of registration materials and marks
• Easily adjusted for optimum performance
• Very accurate and repeatable with unnoticeable migration from start up to full speed
• High Quality and High Reliability
