Title:
強磁性対象物体の動きを検知するための磁場センサ
Document Type and Number:
Japanese Patent JP6546657
Kind Code:
B2
Abstract:
A magnetic field sensor operates as a motion detector for sensing a movement of a ferromagnetic target object having features. The magnetic field sensor has a plurality of magnetoresistance elements to generate, in a first channel, a feature signal indicative of a proximity of a feature of a ferromagnetic target object and, in a second channel, an edge signal indicative of a proximity of an edge of a feature of a ferromagnetic target object.
