Description:
The AB-Series GMR sensors are general-purpose gradiometers for use in a wide variety of
applications. Two pairs of unshielded GMR sensor elements provide for directional sensing of small
gradients in large and small magnetic fields. The ability to detect only magnetic gradients allows low
sensitivity to external sources of uniform magnetic field allowing these sensors to work successfully in
high magnetic noise environments such as near electric motors or current carrying wires.
