The present invention relates to the field of inductive contactless sensors, making it possible to detect the position and / or movement of a target sensitive to the magnetic field. The invention consists in producing a miniaturized sensor comprising at least one primary winding generating an alternating magnetic field and at least two secondary windings for receiving this field, the windings being planar. The amplitude of the signal received by each secondary winding is modified by the passage of the target, so that by measuring the amplitude or phase modulation of the signals, we detect the speed and direction of movement, even the position of the object to be detected. <IMAGE> |
