Leuze electronic KRT 18B contrast sensor

In many packaging processes, contrast marks must be reliably detected on film, bag and blister packaging or on labels.

With its integrated three-colour technology (red, green, blue), automatic sensitivity readjustment and an integrated dual-channel IO-Link interface, the KRT 18B colour contrast sensor is suitable for meeting the requirements of rapid packaging processes in foil-bag packaging machines, label detection in filling systems and detecting glossy and faded marks.

The KRT 18B colour contrast sensor is easy to set up by use of an alignment aid and a bar graph indicator (on the rear of the sensor) to indicate signal strength.

Different models are available with various options depending on the application. The Standard model is designed for simple applications, while the Teach model is for more universal use. The Multi-turn model allows for manual optimisation, the Tracking model is for maximum reliability with detecting difficult marks. The Speed model provides precise positioning with fast processes, while the Analog model is designed for signal evaluation in the PLC.

The stainless steel compact housing is designed for high temperature stability and is suitable for use in areas with stringent hygienic requirements with IP67 and IP69K degrees of protection. The KRT 18B also has various mounting options and accessories.
