The invention relates to a contactlessly working eddy current sensor, particularly for detecting essentially flat test objects, comprising at least one sensor coil, eddy currents being able to be induced in the test object. The invention is characterized in that the coil, when passing by the test object, is aligned in such a manner that the coil axis is oriented essentially parallel to a line normal to a surface to the test object, and that the test object can be moved past the sensor coil essentially parallel to the coil axis or the sensor coil can be moved past the test object. A corresponding method is carried out so that an eddy current can occur only once when the test object or coil is passed by.
