1. A method for detecting an electrically and/or magnetically conductive object in surroundings of a sensor head of a device, the method comprising the following steps:

  • emitting a transmitting signal into the surroundings;

    receiving a received signal as a function of the transmitting signal and characteristics of the object and the surroundings;

    analyzing a response signal formed from the received signal;

    the detection being controlled by;

    providing a class system having a plurality of classes differing from one another in at least one object and/or surroundings characteristic;

    classifying instantaneous object and/or surroundings characteristics as a function of the analyzed response signal into one of the classes of the class system, the one class defining a classified class; and

    detecting a further response signal using predefined detection characteristics preset in the classified class.
