Capacitive Label Switches

Contrinex capacitive label sensors feature simple adjustment, reliable operation, and a compact, robust housing. They are used for the detection of labels, adhesive joints, tears and double sheets. Due to their capacitive operation principle, they are able to detect even transparent materials without problem. The material to be detected, e.g. labels on a support strip, is placed in the sensor's slot.
Strip position and label shape are insignificant, considerably facilitating the use of these devices. The sensitivity is easily and quickly set by means of teach-in. This results in optimum adjustment and problem-free material changeability. The housing can be easily separated by loosening two socket-head screws, which enables cleaning without dismantling the base and without the need for readjustment. The sensor's static operating principle and high switching frequency permit very low to very high strip speeds. Offering two slot widths, these sensors are suitable for a wide range of applications.
