Garantta GCS101 Digital Intelligent Color Mark Sensor | High-precision RGB Color Mark Detection, Stable Identification in Packaging And Printing Production Lines

Leave a message

In automated production lines for packaging, printing, and food and pharmaceutical industries, common challenges include difficulty distinguishing between similar colors, accidental triggering during high-speed material handling, and unstable sensor detection due to oil and dust contamination. The Garantta GCS101 digital intelligent color mark sensor, a high-performance color mark detection device, is specifically designed for high-precision color recognition scenarios in industrial automation.

 

This digital intelligent color mark sensor, the GCS101, features an integrated RGB light-emitting element and a 12-bit A/D converter, achieving a resolution of 1/4000. Based on RGB spectral comparison logic, the Garantta GCS101 color mark sensor can accurately distinguish subtle color differences that are difficult to discern with the naked eye. It goes beyond simple brightness contrast, making digital judgments based on color ratios, significantly reducing false positives and false negatives in high-speed production lines. The optical structure employs a coaxial reflective optical path with a scratch-resistant glass lens and is equipped with a nano-anti-fouling coating to resist interference from oil, dust, and moisture. The GCS101 color mark sensor boasts an IP67 protection rating, making it suitable for harsh industrial environments with high humidity and dust levels, and offering enhanced stability during long-term continuous operation. It features a built-in 4-digit digital display and easy-to-use operation buttons for intuitive setup and adjustment.

 

The Garantta GCS101 digital intelligent color mark sensor supports two detection modes: color mark mode, emphasizing ultra-high-speed response and suitable for continuous material feeding; and color mode, focusing on high-precision color discrimination to meet the needs of distinguishing multi-colored materials. The device has built-in parameter storage, allowing for the saving of multiple color mark formulas for one-click recall when switching products, reducing production line changeover and debugging time. A button lock function is also included to prevent accidental parameter changes on-site. Hardware output supports both NPN and PNP types, making it compatible with most packaging machines, bag making machines, printing and slitting machines, labeling machines, and other automated equipment. Its compact design minimizes installation space, making it convenient for retrofitting existing equipment and integrating with new machines.
