Application Notes
Use Of GMR Magnetic Field Sensors
General Considerations
All of NVE’s GMR Magnetic Field sensors have a primary axis of sensitivity. The figure below shows
an AAxxx-02 Series GMR Magnetic Field Sensor with a cut away view of the die orientation (not to
scale) within an SOIC8 package.
Flux Concentrators
Axis of Sensitivity
S ENSITIVE M AGNETIC A XIS – AA00 X -02 S ENSOR
The flux concentrators on the sensor die gather the magnetic flux along the axis shown and focus it at
the GMR bridge resistors in the center of the die. The sensor will have the largest output signal when
the magnetic field of interest is parallel to the flux concentrator axis. For this reason, care should be
taken when positioning the sensor to optimize performance. Although sensor position tolerance may
not be critical in gross field measurement, small positional variation can introduce undesirable output
signal errors in certain applications.
