True color recognition sensors “read” colors by emitting white light, analyzing three beams of reflected colored light (red,blue, green), then measuring the level of light reflected back on each wave length.
The level of reflected light is compared to the value stored in the sensor’s memory. If the value is within its tolerance limits, recognition of that value triggers the output. Typical uses of true color recognition sensors include sorting by product color, or exactly matching a memorized color to that of a passing target.
Color sensors open up a field of diverse applications in sectors such as packaging technology, robotics, automation, quality assurance, and the process control industry. Simplify and speed up automated processes with diverse color sensors - for the detection of shade in rugs and textiles and of color markings on packaging and labels.
