An inductive sensor (100) for a motor vehicle, includes: a field coil (101) designed to form an electromagnetic field, a coil (103) for measuring a magnetic field and designed to provide an output signal representative of the position of a metal target (102) in the magnetic field formed by the field coil (101), and at least two electric circuits (111) connected simultaneously in parallel to the terminals of the field coil (101), each electric circuit (111) including an inverter element (112) and a capacitive element (113), and forming, together with the field coil (101) an electric oscillator (110) designed to form an AC voltage at the terminals of the field coil (10) via electric resonance, the electric oscillators (110) being of the same resonance frequency.
