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.

Abstract
A method for detecting an electrically and/or magnetically conductive object in a vicinity of a sensor head of a device, having the following steps:
- emitting a transmitting signal into the surroundings,
- receiving a received signal as a function of the transmitting signal and the characteristics of the object and the surroundings,
- analyzing a response signal formed from the received signal. According to the invention, the detection is controlled by
- providing a class system having a number of classes, which differ from one another in at least one object and/or surroundings characteristic, and
- classifying instantaneous object and/or surroundings characteristics as a function of the analyzed response signal in a class of the class system, and
- predefining detection characteristics which are preset in the classified class, a further response signal being detected using the predefined detection characteristics.
