Leuze electronic’s new KRT 3B contrast sensor is said to be the smallest in the world, fitting within what Leuze calls a ‘3 series’ housing. It is also said to be a high-performance device, equal to larger units in terms of its function and range.
Performance such as short response times of 50 µs and high repeatability, as well as features such as IO link make configuration and implementation easy. Three teach processes: two-point teach, static one-point teach and dynamic two-point teach, provide optimal set up for every type of machine use.
The switching thresholds ascertained via teach-in can be changed during running operation in four per cent increments with EasyTune. This online switching-threshold correction, makes it possible to quickly 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 ‘YellowBoost’.
Contrast sensors are widely used in packaging machinery and automation technology.
