Abstract

A sensor for locating metal or magnetic objects includes a first and a second transmitting coil and one receiving coil. The receiving coil includes a first and a second receiving sub-coil. The first transmitting coil and the first receiving sub-coil are arranged in a first plane. The second transmitting coil and the second receiving sub-coil are arranged in a second plane. The first transmitting coil and the first receiving sub-coil are offset in relation to the second transmitting coil and the second receiving sub-coil with respect to a common center axis which passes vertically through the planes. The first receiving sub-coil is configured differently than the second receiving sub-coil.
