How to Choose a Color Sensor That Delivers Both High Precision and High-Speed Detection?

In modern industrial automation and smart manufacturing, rapid and accurate color recognition forms the foundation for critical processes like sorting, quality inspection, and positioning. Faced with a vast array of detection devices on the market, engineers often find themselves torn: should they prioritize high color-discrimination accuracy or ensure detection speed on the production line? Is there a solution that offers the best of both worlds? Today, we proudly introduce FGS-22, the flagship color sensor from Fuwei Electronics. Its exceptional performance will resolve your selection dilemma once and for all.

Core Advantage 1: Intelligent Dual Mode – One Sensor for Dual Challenges

The FGS-22's core appeal lies in its revolutionary switchable dual-detection mode design. This elevates it far beyond single-function devices, making it an indispensable ally for flexible production.

High-Precision Color Mode: Switch to this mode when you require extremely fine differentiation of color differences. The FGS-22 simultaneously illuminates R (Red), G (Green), and B (Blue) primary color LEDs. It identifies colors by analyzing the precise ratio of RGB hues in the reflected light from the object. This advanced color sensor technology effectively overcomes ambient light interference and surface texture variations, achieving highly reliable identification of complex colors. It is ideal for high-precision applications such as product quality grading and paint color difference inspection.

High-Speed Color Mark Mode: On the production line, every millisecond counts. Switching to color mark mode reveals another dimension of this powerful color sensor. It intelligently activates the “Optimal LED Auto-Selection Function,” automatically selecting the single-color light with the highest contrast against the background from the RGB LEDs for detection. This monochromatic, high-contrast detection method significantly boosts response speed, enabling stable capture of fast-moving color marks. It excels in high-speed applications like packaging positioning and material tracking.

Core Advantage 2: Extended Detection Range, Enhanced Installation Flexibility

Constrained by limited installation space? The FGS-22 delivers with its exceptional 18-28mm detection distance. Through precision circuit design and an optimized optical system, this color sensor achieves an extraordinary detection range. This enables reliable detection from greater distances, offering greater flexibility and tolerance in mechanical design while effortlessly adapting to complex installation environments.

Core Advantage 3: Rectangular Spot Pattern for Enhanced Shape Matching Reliability

The shape of the detection spot directly impacts application success. The FGS-22 innovatively adopts a rectangular spot design, measuring approximately 1.5mm x 7mm at the standard 23mm detection distance. This elongated rectangular spot is particularly suited for detecting striped color marks, edge positioning, or minute colored markings. Compared to traditional circular spots, it provides more complete coverage of the target area, reduces positioning errors, and avoids detecting background interference zones, significantly enhancing detection stability and accuracy.

Summary

The FGS-22 color sensor from Fuwei Electronics is more than just a detection component—it's an intelligent solution integrating high-precision color analysis with high-speed response performance. Through its innovative dual-mode switching, it breaks the traditional barrier between precision and speed. With its ultra-long detection range and unique rectangular spot, it adapts to more demanding field applications. Whether tackling precise color sorting or high-speed assembly line tracking, the versatile FGS-22 color sensor excels effortlessly, becoming your reliable partner for boosting production efficiency and product quality.
