Abstract
A method for operating a sensor system, having at least one capacitive sensor element, which is attachable to the surface of machines or machine parts, electrical field lines on the sensor element changing in the event of an approach and/or a contact of a body or object, and the at least one sensor element being connected to a control unit, which, based on the detected change of the field lines of the at least one sensor element, triggers a safety function on the machine or the machine part. The at least one sensor element has, in addition to fulfilling the safety function, an operating function, which is concluded from the location of the at least one sensor element and the time curve of the change of the field lines, and the safety function has priority over the operating function in a base state of the sensor system.
