Zusammenfassung:The invention relates to an Inductive position sensor (1) comprising at least one transmit coil (2), an absolute position receive coil pair (3, 4), a high-resolution position receive coil pair (5, 6) and a conductive moving target (7),wherein the absolute position receive coil pair (3, 4) and the high-resolution receive coil pair (5, 6) together define a measurement area of the inductive position sensor (1) and the moving target (7) can move in this measurement area,wherein the absolute position coil pair (3, 4) has a first sine receive coil (3) and a first cosine receive coil (4), both (3, 4) having one period over the measurement area of the inductive position sensor (1),wherein the high-resolution position receive coil pair (5, 6) has a second sine receive coil (5) and a second cosine receive coil (6), both (5, 6) having at least two periods over the measurement area of the inductive position sensor (1),which is characterized in thatthe absolute position receive coil pair (3, 4) and the high-resolution position receive coil pair (5, 6) are arranged in the same area of a printed-circuit board (8) of the inductive position sensor (1).
