<p>The invention concerns a device for detecting the position of an object comprising at least one magnet (10) integral with said object (11) capable of moving in front of a first and second set of magnetically sensitive elements (12, 13), each set comprising at least one element and a differential processing circuit (14) for determining the position of the object. Said circuit comprises a differential circuit connected to the elements, comparing means also connected to the elements and to the differential processing circuit, the first and second sets being spaced by a distance less than the length of the magnet and such that the comparing means enable to trigger the processing circuit when the magnet is close to the centre of said distance.</p> |
