Abstract

A position sensor includes a shaft to be detected, a first magnet being fixed to the shaft and having a first polarity vector parallel to an axis of the shaft, a second magnet being disposed opposite to the first magnet and having a second polarity vector crossing the first polarity vector substantially orthogonally three-dimensionally, and first and second semiconductor magnetoresistive elements being disposed over the second magnet and functioning as a magnetoelectric transducer having a magnetosensitive axis substantially orthogonal to the first and second polarity vectors. The first and second elements generate an output responsive to an axial movement of the shaft.
