Contrast sensors, also referred to as contrast scanners, are widely used in packaging machinery and automation technology for the detection of print registration marks. Leuze electronic offers a wide range of contrast sensors in a variety of housings, but its new KRT 3B contrast sensor is believed to be the smallest in the World, fitting within what Leuze calls a ‘3 series’ housing.

Performance features include extremely short response times of 50 µs and high repeatability, while IO-link capa

Furthermore, the switching thresholds ascertained via teach-in can be changed during running operation in 4% increments with EasyTune. This online switching-threshold correction, makes it possible to respond to modified process parameters without performing a new teach-in.

Another special feature is ‘YellowBoost’, a system developed by Leuze to optimise contrast detection in the white-light version of the contrast sensor. Although this affects all wavelengths, smoothing of the signal deviation is strongest in the yellow-light range, hence the name.
