A device and method for detecting the position and velocity of a test object relative to a sensor, the sensor and the test object being arranged such that they can be displaced relative to one another. In one embodiment, the sensor has a measuring coil with one or more voltage tap(s) and has a target that is placed on the test object while being electromagnetically coupled to the measuring coil. An electronic component for adding the voltages tapped on the sensor is assigned to the sensor. The invention is, with regard to a simplest possible design of the sensor, characterized in that for simultaneously measuring position and velocity, the target comprises two parts, one part being made of an electrically conductive material and the other part being provided in the form of a magnet, and in that an evaluation circuit determines, based on the output signal of the electronic component for adding the tapped voltages, a voltage component Uthat is proportional to the position of the target, and a voltage component Uthat is proportional to the velocity of the target.
