Abstract
A sensor for locating metallic objects, in particular a metal sensor for building materials, includes at least one transmission coil and at least one reception conductor loop system that are inductively coupled to one another. The reception conductor loop system is made up of conductor structures on a printed circuit board. A second reception conductor loop system can be provided, which is situated coaxial to the first reception conductor loop system in a common first plane with it on the printed circuit board. The sensor preferably operates in a frequency range between 1 kHz and 10 kHz.
