The number of labels used in the market is steadily increasing. The range varies from transparent labels “non-label-look”, printed and partially metallized label up to booklets with integrated operating manual. In order to safely detect this variety of labels, mostly just to have one physical function principle for label sensors is not sufficient. Therefore, S-sensors is offering a large program regarding that range.
 

Optical label sensors
are features by a very high switching frequency, a short response time and a high resolution. Large fork openings offer enough room for thicker label material. Versions with a very flat lower branch enable the detection of labels directly on the dispenser edge, guaranteeing a considerably increased precision of dispensing.
 

Capacitive label sensors
detect very thin as well as transparent labels and allow their exact positioning. Capacitive label sensors can also be used for the detection of double-layers as well as bonding points.
 

Ultrasonic label sensors
detect, despite their large fork opening, very thin and transparent film labels and offer enough space for thicker, folded labels. A clear operating menu with integrated display enables an intuitive adjustment of the sensor functions without operating
manual.

Ultrasonic label sensors do not just detect very thin and transparent foil labels. They also reliably detect metalized labels and provide sufficient clearance for thicker, folded booklets. The innovative dual operation concept-optionally implemented using IO-Link or teach-in with manual threshold value adjustment-makes it possible to put the sensor into operation quickly.
