Even with a gloss finish or fading brand these can be reliably detected due to the automatic Empfindlichkeitsnachregelung.
For easy set-point adjustment of different variants, each with self bar graph for the optimal display of signal quality: A variant has two Teach heads for the synchronization to the background and mark, another via potentiometer and color selection button. For a reliable operation is possible with just a single shot in high contrast to the brand. Changes of film formats for example on packaging machines can be quickly and easily adapted and by an extensive recipe management via IO-Link interface.
Thanks to its space-saving Ecolab tested IP67 / IP69K-metal housing and its high switching frequency up 25kHz which enables fast response, the sensor is particularly suitable for fast packaging processes in Foil Bag packaging machines and for label detection in bottling plants. An alignment to the focal point 13 mm is included, so that the sensor can be easily aligned and put into operation.
