Leuze KRT 3C contrast sensor

The KRT 3C contrast sensor from Leuze is the smallest contrast sensor the company has made for the packaging industry. It is designed to detect reliably and position accurately even if there are only small contrast differences, including on glossy surfaces or highly reflective materials. This is made possible by utilising multi-colour 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 their packaging and labelling processes.

The KRT 3C detects contrasts with a short response time of 50 µs and minimal signal jitter, helping to achieve optimal machine throughput. With its small dimensions of 11 x 32 x 17 mm, the sensor is also designed for tight installation spaces. This means it can be fitted almost anywhere, and users can set up the KRT 3C via the integrated IO-Link interface.

The KRT 3C housing is robust, protection rated to IP67 and IP69K and ECOLAB-certified, so that it can handle aggressive cleaning agents.
