KT8 Contrast Sensor
Brand: Sick AGThe 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.
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.
Features- Wide selection of varying distances, depending on the application
- Precise detection of the smallest marks and objects, e.g., 1 x 1 mm²
- Reliable operation, even with unsteady objects
- Easy integration into machine designs, thanks to standard CAN protocol
- Access to the sensor via the control system saves the machine operator time and effort during configuration
- Individual, application-specific configuration and settings
- Automatic drift correction ensures high production reliability with faded print marks and other difficult to detect marks
- Reliable operation, even with high-gloss reflective surfaces, increasing throughput
