Products contract sensors IO-Link KRT 3C Leuze packaging

Leuze has introduced the KRT 3C contrast sensor, the company’s smallest contrast sensor for the packaging industry.

The contrast sensors are developed to detect defined markings on objects during packaging processes.

The contrast markers are located on film, bag, and blister packaging or on labels.

The new compact contrast sensor of the 3C series can be used flexibly with different transmitter colours (RGB light, white light, or laser-generated red light) for common colour and gray value combinations. It is said to detect even slight contrast differences reliably and precisely, as well as print marks even on glossy materials.

The sensor housing is 11 x 32 x 17 mm. The plastic housing covers degrees of protection IP67 and IP69K. ECOLAB certification confirms the housing’s resistance against cleaning agents commonly used in the packaging industry.

All settings for integration and operation of the sensors as well as for the case of format changes of the products can be easily performed via the IO-Link interface, the company says.
