Color sensors detect colors by comparing the detected color value with a previously stored reference value. They are the right solution whenever the color of an object or marking can serve as a sorting or inspection criteria. Depending on the configuration and specified tolerance values of the system, the result is output as a switching signal.

Detects even very slight color nuances and masters changing distances

With its high color resolution and an innovative teach-in method, the new High Resolution color sensor can even distinguish between fine color nuances. It also detects color gradients and structured materials like wood. Besides sensing distances of up to 500 mm, the High Resolution comes with an automatic sensing distance regulation feature: The High Resolution detects colors precisely even at changing distances and with varying object sizes. Furthermore, the full color TFT sensor display shows color values (L*a*b or RGB) as well as the similarity of a detected color to a taught-in color. Up to 24 colors per identification task (job) can be transferred via the IO-Link interface and saved externally.
