发明名称 Contactless position sensor with optimized magnetic volume and magneto sensitive probe
摘要 A magnetic position sensor, linear or rotary, including a stator and at least a mobile part along at least a direction OX, with an effective stroke Xc. The stator includes at least two components made of soft magnetic material defining at least a secondary air gap in which is housed at least a magneto-sensitive probe. Each stator part component has a length Xs in the direction OX not less than Xc. The magnets of one mobile part are extended over at least one edge by a mobile ferromagnetic component having a thickness e, in the direction of a magnetization of one magnet, such that 0.1 L<e<0.9 L, L being a length of the magnet in a magnetization direction, and moving parallel to the stator ferromagnetic components at a constant minimum distance and having a magnetization perpendicular to OX and a length in the direction of displacement OX not less than Xc.
