Contrast Sensor, Hygienic & Washdown
Leuze KRT 55

Ideal for the food industry! ECOLAB/CleanProof+ Certification.

Contrast scanners detect marking, even those with only slight contrast with respect to the background, at very high processing speeds. Automatic adaptation of the wavelength allows the slightest changes in gray value to be detected, independent of the color combination of the marking and background.

With the KRT 55 contrast scanners, devices are available with two transmitter variants - RGB light and white light - that are characterized by extremely short response times of 50 µs and high repeatability. With regard to their configuration options, they also perform big.

Here, IO-Link makes on-site configuration possible with unmatched simplicity and reproducibility. With the three teach processes: 2-point teach, static 1-point teach and dynamic 2-point teach, the optimum teach process is available for every type of machine use. Furthermore, the switching thresholds ascertained via teach-in can be changed during running operation with EasyTune. By means of this online switching-threshold correction, it is possible to quickly respond to changed process parameters without performing a new teach-in.

One special feature is YellowBoost, a form of yellow support developed by Leuze with which contrast detection of the white-light contrast scanner is optimized. Although this affects all wavelengths, the improvement of the signal deviation is strongest in the yellow-light range, hence the name of the function.

With IO-Link in combination with the EasyTune switching threshold correction and YellowBoost, Leuze electronic has implemented globally unique features in the unrivaled stainless steel contrast scanners.
