NVE AAT006-10E

NVE AAT006-10E
The AAT006-10E angle sensor from NVE use unique tunnelling magnetoresistance (TMR) elements for large signals and low power consumption. This sensor is a high sensitivity version of NVE’s AAT angle sensor family, operating with as little as 15 Oe magnetic field. The sensor provides sine and cosine signals defining the angle of rotation, outputs are proportional to the supply voltage and peak-to-peak output voltages are much larger than conventional sensor technologies. The NVE AAT006-10E sensors consist of two half-bridges with a typical bridge resistance of 1.25MΩ for very low power applications.
  • Surface-mount tunnelling magnetoresistance (TMR) angle sensor technology
  • Supply voltage of +5.5V
  • Microwatt power consumption
  • High output signal without amplification
  • Immune to airgap variations
  • Operates with as little as 15 Oersted field.
  • Sine and cosine and outputs
  • Operating temperature range of −40°C to +125°C
  • Ultraminiature TDFN6 packages

The AAT006-10E sensor contains four sensing resistors at 90° intervals. The resistors are connected as two half-bridges providing the sine and cosine voltage outputs. For each half bridge the resistance of one element increases and the other decreases as the field rotates, thus the bridge resistance, device resistance and output impedances remain constant with rotation.

Typical applications for the ATT series include:

  • Battery powered applications
  • Knob position sensors, rotary encoders
  • Automotive rotary position sensors
  • Motor shaft position sensors

The below table gives the full specifications of the NVE AAT angle sensor series including the AAT006-10E:

NVE AAT006-10E Specifications

1. Large magnetic fields CANNOT damage NVE sensors.
2. "Fixed Bias” means a fixed airgap between the bias magnet and sensor so the magnetic field at the sensor is constant.
3. “Variable Bias” means the magnetic field strength at the sensor can vary across the specification range.
4. Maximum deviation of either output from an ideal sine wave.

VIDEOS
Angle Sensor on a Lego Car

NVE put an angle sensor on a remote-control Lego car to demonstrate the sensor's awesome precision and airgap tolerance. The AAT series sensor has a precision better than one degree, which is about 1/64" for the 2" diameter Lego wheels. AAT Sensors are "awesome" for motion control because they allow wide magnet airgaps for simple positioning, large output signals and low output impedance allow direct interface to microcontrollers like Arduinos. They are absolute rather than relative sensors, and they're small.
Angle Sensor Live Demonstration

NVE's Jay Brown demonstrates that AAT-Series TMR sensors are extremely small, sensitive, and low power.
Arduino Angle Sensor Demo (short version)

The AAT003 non-contact angle sensor in a stepper motor servo system. This demonstration shows the unique capabilities of AAT-Series tunneling magnetoresistance sensors. NVE use a simple Arduino controller with a modified clock as a position indicator.
