Industrial color sensors feature high sensitivity and long-distance detection, supporting two detection ranges: 30-70mm and 50-500mm. Equipped with a high-brightness white LED light source, they accurately identify color differences and color mark positions on various targets. With a response time as fast as 200µs and support for NPN/PNP and NO/NC switching, they flexibly adapt to multiple industrial control systems.
Long-distance color sensors are commonly used in industrial production lines, logistics inspection, and printing/packaging scenarios. Color sensors can identify different colors or color marks at extended detection ranges, making them suitable for target detection in high-speed transmission environments. For instance, product sorting on packaging assembly lines, color mark recognition in printed materials, and color monitoring of textile fabrics all rely on such sensors. Compared to short-distance sensors, they better handle complex operating conditions while ensuring detection accuracy and stability.
Compared to standard color sensors, long-distance models offer significant advantages in detection range, light source power, and interference resistance. Standard sensors are suitable for close-range detection around 10mm, while long-range products enable stable recognition at distances of tens to hundreds of millimeters. Additionally, they typically feature high-brightness light sources and more sensitive receivers, maintaining accurate detection in complex lighting or vibrating environments. The long-distance color sensors broader applicability makes them particularly suitable for industrial automation scenarios.
To guarantee stable detection with long distance color sensors, pay close attention to installation positioning and environmental conditions. First, ensure the sensor remains within the recommended detection distance from the target object and avoid excessive angular deviation. Second, regularly clean the lens to prevent dust or oil residue from affecting optical recognition. Additionally, select models featuring automatic calibration or sensitivity adjustment capabilities to adapt to targets of varying materials and colors. Proper power and signal wiring also minimizes interference, ensuring long-term reliable operation.
