Abstract:
1. A magnetic linear position sensor comprising: a) a first yoke which is made of soft magnetic material, having a lower horizontal surface and an upper surface formed of two inclined planes arranged in a V-shape; b) a first magnet which is placed on one of said inclined planes of the first yoke, and whose upper surface is the N pole and is inclined; c) a second magnet which is placed on another inclined plane of the first yoke, and whose upper surface is the S pole and is inclined in a direction opposite to the upper surface of the first magnet and in a direction facing the surface of the first magnet; d) a second yoke having a horizontal planar surface which is placed at a position opposing the first magnet and the second magnet through an air gap and is made of soft magnetic material; and e) a magnetoelectric transducer which is placed in the air gap.
