MAGNETORESISTIVE PROXIMITY SENSOR

摘要

A magnetoresistive proximity sensor (1) comprises a source body (2) provided on a detection plane (A) and adapted to generate a magnetic field (B), at least one pair of magnetoresistive sensitive elements (3, 4) arranged in the generated magnetic field (B), each sensitive element (3, 4) being adapted to emit a signal indicating a local variation of the generated magnetic field (B), when it is crossed by a ferromagnetic body (5) to be detected, so as to detect the instantaneous position of the ferromagnetic body (5) crossing in the aforementioned detection plane (A).
