Abstract
The invention concerns a magnetic position sensor for delivering an electric signal proportional to the position, including of a mobile part having at least a thin permanent magnet movable in a main air gap. The air gap is defined by two ferromagnetic parts and, the ferromagnetic parts defining between them a secondary air gap including a sensor sensible to magnetism. The mobile part is arranged such that penetration on the magnetic part into the main air gap is partial over part of the useful travel so that the sensor sensible to magnetism delivers a signal proportional to the degree of engagement of the magnetic parts in the main air gap.
