Patent ID: 8063627

Claim:
Linear sensor ( 1 ) for measuring an axial path (L o ) of a mobile part ( 2 ) sliding in an axial direction ( 20 ) in a frame ( 3 ) with a transverse wall ( 30 ) perpendicular to said axial direction ( 20 ), comprising a mobile part ( 4 ) cooperating with a fixed part ( 5 ), said mobile part ( 4 ) comprising: a longitudinal element ( 40 ) cooperating at a lower end ( 400 ) with said mobile part ( 2 ) using a first connecting means ( 6 ), so that said lower end ( 400 ) is mobile in an axial path following that of said mobile part ( 2 ), any translation of said mobile part ( 2 ) causing an axial translation of said lower end ( 400 ), and a displacement of said longitudinal element ( 40 ) causing a corresponding displacement of an upper end ( 401 ); a magnetic field source ( 41 ) integral with said longitudinal element ( 40 ) at said upper end ( 401 ), using a second connecting means ( 42 ), so that any displacement of said upper end ( 401 ) causes the displacement of said source ( 41 ), said fixed part ( 5 ) comprising a receiving means ( 50 ) for said magnetic field, opposite said source ( 41 ) and capable of sending a primary signal, depending on said axial path, to a transducer ( 51 ) capable of converting said primary signal into an electrical signal S transmitted to a connector ( 52 ) making it possible to transfer said electrical signal (S) to an external electrical circuit; and characterized in that said fixed part ( 5 ) comprises an angular redirection means ( 53 ) cooperating with said longitudinal element ( 40 ) using an angled part ( 402 ) and thus transforming said axial path of said lower end ( 400 ) into a radial path of said upper end ( 401 ).
