Zusammenfassung:The invention relates to a sensor arrangement for the capacitive sensing of approximations close to a motor vehicle (1), comprising a capacitive sensor electrode (2, 3; 25) and at least one control and evaluation device (4) which is coupled to the sensor electrode and which senses a change in the capacitance of the sensor electrode. Said sensor electrode (2, 3; 25) is an elongate flat electrode, wherein in the longitudinal direction of the sensitive electrode, first electrode sections (a) having a first surface width and a first deformability alternate with second sections (b) having a second, narrower surface width and a second deformability such that electrode surfaces, which have different levels of deformability, have different measurements and which are continuously conductive and joined, are formed. A deformable and electrically insulating sheathing (30; 40) surrounds the sensor electrode.
