NVE AA006-02E

The AA006-02E analog magnetic sensor from NVE detect absolute magnetic fields, with a sensitivity range of 5Oe to 35Oe and sensitivity of 0.9mV/V-Oe to 1.3mV/V-Oe. NVE’s AA series of analog Giant MagnetoResistive (GMR) sensors offer unique and unparalleled magnetic sensing capabilities. Utilising NVE’s patented GMR materials and on-chip flux concentrators to provide a directionally sensitive output signal, these sensors are characterized by high sensitivity to applied magnetic fields, excellent temperature stability, low power consumption, and small size, making them suitable for use in a wide variety of applications from rugged industrial and automotive position, speed, and current sensors, to low-voltage, battery-powered sensors for use in hand-held instrumentation and implantable medical devices.

The AA magnetic sensor series are sensitive in one direction in the plane of the IC, with a cosine-scaled falloff in sensitivity as the sensor is rotated away from the sensitive direction. Also, these devices provide the same output for magnetic fields in the positive or negative direction along the axis of sensitivity (omnipolar output). All GMR sensors are designed in a Wheatstone bridge configuration to provide temperature compensation.

The basic AA series of GMR sensors are general purpose magnetometers for use in a wide variety of applications. They exhibit excellent linearity, a large output signal with applied magnetic fields, stable and linear temperature characteristics, and a purely ratiometric output.

Typical applications for the AA series include:

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