a capacitive sensor module with a sensor electrode which is used to detect the entry of an object into a space ahead of the sensor electrode , wherein the sensor electrode is formed from a wire . parallel to the sensor electrode , auxiliary electrodes extend within a plastic carrier that possesses recesses to receive the sensor electrode and the auxiliary electrodes and partially surrounds them along their circumference . the sensor electrodes can be pressed into the plastic carrier by overcoming an elastic forming force and are held within their recesses by the elastic reshaping process .
