The AB-Series sensors are differential devices, or gradiometers that reject common mode magnetic fields, making them ideal for high magnetic noise environments (e.g. motors or current-carrying wires). They have operation characteristics similar to the NVE AA-Series of sensors, but with the bipolar linear output characteristics of a differential sensor, which detects field gradients. The AB-Series is sensitive to a field gradient along the part axis.
These GMR sensors are designed in a Wheatstone bridge configuration to provide temperature compensation

Typical applications for the AB series include:

• Motion, speed and position sensing
• Low-field sensing
• Motor commutator sensors
