Abstract

A capacitive sensor (10) for a roller (12) of a roller track is provided which has a plurality of measuring electrodes (18) as well as a measurement unit (28) for determining capacitances between measuring electrodes (18) to recognize an object (42) located at the roller track with reference to capacitance changes. In this respect, at least some of the measuring electrodes (18) are arranged co-rotating with the roller (12, 16).
