A 0.8 x 0.4 inch (21 x 10 mm) breakout board with the AAT101-10E Full-Bridge Tunneling Magnetoresistance (TMR) analog angle sensor.
The board has a pre-soldered sensor and footprints for a standard 0.1" (2.54 mm) header and a common, 1 mm pitch card-edge connector.
The board can be powered by a 0 to 5.5 V supply and provides full-bridge sine and cosine analog outputs.
AAT101-10E Angle Sensors use a Tunneling Magnetoresistance (TMR)
full-bridges to produce a very high output signal without amplification. The sensors also have a wide
airgap tolerance and high device resistance for low power. Sine
and cosine outputs provide full quadrature.

The angle sensors are typically used with a split pole magnets such as
NVE part no. 12249 or 12426.
An Evaluation Kit is available with an angle sensor, circuit board, unity-gain buffer amplifier, split-pole magnet, and a plastic magnet locating fixture.
Note: Please purchase in increments of 100 when purchasing quantities of 100 or more.
The kit includes a circuit board with an AAT101-10E Full-Bridge Angle Sensor, which provides two differential analog outputs, 90 degrees out of phase. The circuit board can be powered with a 0 V to 5.5 V power supply. An angular reticle on the circuit board aids in characterizing output versus angle.
The kit also includes a split-pole magnet and a plastic magnet locating fixture.
The AAT101-10E Angle Sensor typical output amplitude is 400 mV/V peak-to-peak for each output.
