Simplify and accelerate your automated processes with the versatile BFS color sensors from Balluff. Use for recognizing color nuances in textiles, on painted sheets, as well as colored markings on packaging or labels. Whether TrueColor or RGB, our color sensors sort out reject parts and ensure uniformly high product quality. In this manner, they contribute to a reliable production process.

Balluff's TrueColor sensors see like the human eye with a higher resolution. They differentiate between subtle color nuances and evaluate the quality of the finished pieces. In addition, they test with a precision that is unaffected by human failings. Always objective and absolutely incorruptible.

RGB color sensors detect and distinguish between different colors by measuring the intensity of red, green and blue light components. The fact that they perform multiple color measurements per second is a major advantage in applications where rapid color changes or objects of different colors in succession need to be detected.
