Low Power, Low Voltage Applications
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.
