Today, Wuxi Rihuan Sensing Technology Co., Ltd. will introduce the core differences between color mark sensors and color sensors.
Color mark sensors and color sensors both belong to photoelectric sensors. However, there are significant differences in their principles, functions, applications, and installations. Choosing the right model is essential to ensure the stable operation of the production line.
1. Different working principles
Color mark sensor
Works by detecting the difference in gray value and contrast on the object's surface. It is more appropriately called a contrast/gray value sensor, focusing on identifying the boundary between light and dark.
Color sensor
Divides reflected light into red, green, and blue primary colors and precisely compares them with the preset standard color to achieve color recognition and measurement.
2. Different functions and applications
Color mark sensor
Used for locating color marks and detecting contrast differences, mostly applied in packaging and printing industries for marking recognition and cutting positioning.
Color sensor
Can accurately identify, measure, and monitor color changes, suitable for high-precision color sorting, color detection, and quality control scenarios.
3. Different structures and installation methods
Color mark sensor
The light source shines vertically on the object, and the receiver is installed at an acute angle to reduce the interference of direct light, improving the detection accuracy.
Color sensor
Integrated design of emission and reception, directly aligning with the measured object, and determining the color by analyzing the RGB bands.
Summary
Color mark sensor: Locate marks, compare contrast
Color sensor: Recognize colors, measure colors
Correct selection of models is essential for achieving more accurate detection and stable operation.
The Rihuan Sensor focuses on the research and production of color mark sensors and color sensors. Its products have high precision, strong anti-interference ability, and are suitable for various industrial scenarios, providing reliable detection solutions for your automated production lines.
