Leuze KRT 3C contrast sensor

Click2Contact

The Leuze KRT 3C contrast sensor can be integrated into packaging processes because of its multicolour capability and small size. It is able to detect small contrast differences on glossy surfaces or highly reflective materials. This is made possible by the multicolour functionality: red, green and blue light as well as white and laser red light will not allow any object or printed label to pass through unnoticed. This allows users to select the right light source for any material and contrast mark colour for packaging and labelling processes.

The product is designed to detect contrasts precisely and with a response time of 50 µs (laser: 125 µs) and minimal signal jitter. With its small dimensions of 11 x 32 x 17 mm, the sensor is designed for tight installation spaces. This means it can be fitted almost anywhere. Users can set up the KRT 3C via the integrated IO-Link interface. This also speeds up product format changeovers.

Its housing is robust, protection rated to IP67 and IP69K and ECOLAB-certified. It can handle aggressive cleaning agents.
