AMR Sensors FAQ

Characteristics

How can AMR sensors be differentiated from hall ICs, which are used to detect vertical magnetic fields? (Fully compatible)

AMR sensors differ in terms of the direction of the magnetic flux detected. It depends on the application, but in the case of mobile phones, external leakage of magnetic flux may adversely affect magnetic commuter passes that may be carried together by phone users. Since AMR sensors detect magnetic fluxes in a different direction compared with hall ICs, the magnet is positioned in a different direction, making it possible to prevent external leakage of flux. No AMR sensors have been replaced by hall ICs as a measure against external leakage.
