A contactless angular offset analog sensor, of the magnetic inductance type, includes a first portion forming a detector. The detector includes at least one substrate plate carrying at least one flat spiral winding, and at least one core layer of material with high magnetic permeability and low saturation field over at least one portion of the winding. The detector is adapted to coact with a device for processing the electrical signal measured at the terminals of the winding. The sensor also includes two rotors each having at least one magnet, disposed over a predetermined angular sector. The rotors are movable about a same axis identical to the axis of the winding. Each magnet generates in the plane of the core layer a magnetic field of a value greater than the saturation field of the core layer over at least a portion of the surface of the winding.
