The KT8 sensor family features two variants. The first variant, the KT8L, enables very reliable detection of the smallest contrast marks and objects thanks to the precise laser. Lasers are used in contrast sensors for long sensing distances (up to 800 mm) or for detecting very small objects. The KT8L gives you both! Thanks to the two light spot sizes, the smallest elements can be detected with < 0.3 mm and larger objects and marks with approx. 3 mm. 3-color LED, gloss adjustment, automatic drift correction and short response times are what make this device the ideal product.
