With the KRT 3C contrast sensor, Leuze presents the smallest contrast sensor it has ever made for the packaging industry. Plant operators benefit from a compact device that can be used in many different ways: The KRT 3C detects reliably and position-accurately even if there are only small contrast differences and with glossy surfaces or highly reflective materials. This is made possible by the multicolor 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 color for their packaging and labeling processes.

Tight space? No problem!
The KRT 3C detects contrasts very precisely and reliably and with a short response time of only 50 µs (laser: 125 µs) and minimal signal jitter. This helps to achieve optimal machine throughput. Advantage in small spaces: With its small dimensions of 11 mm x 32 mm x 17 mm, the sensor is designed for tight installation spaces. This means it can be fitted almost anywhere. Users can easily setup the KRT 3C via the integrated IO-Link interface. This also speeds up product format changeovers.
Really resilient
The housing is robust: It meets degrees of protection IP67 and IP69K. The KRT 3C is also ECOLAB-certified, so it can even handle aggressive cleaning agents.
