The KT8 sensor family has two variants. The first, KT8L, supports extremely reliable detection of the smallest contrast marks and objects thanks to its precise laser. Lasers are used in contrast sensors for long sensing distances (up to 800 mm) or to detect very small objects. The KT8L supports both. Two light spot sizes are available: <0.3 mm for detecting the smallest objects and 3 mm for larger objects and marks. The second variant, KT8 CAN, is characterized primarily by its ability to communicate. This enables users to adjust the sensor to meet their specific requirements and easily integrate additional functions into their machines. Virtually any number of parameter sets (i.e., taught-in sensor settings) can be stored in the machine controller via the CAN interface, e.g., for different packaging or prints. In addition, important process data such as contamination or current switching thresholds can be queried via the CAN interface. This product is topped off by a 3-color LED, gloss adaptation, automatic drift correction, and fast response times.
