TMR

TMR

TMR, or Tunneling Magnetoresistance utilises a magnetic tunneling junction element, comprising of a ferromagnetic free and pinned layers, separated by a dielectric spacer layer. The magnetism direction of both ferromagnetic layers can be switched; when parallel, electrons can make a quantum leap to tunnel through the spacer layer. At Rhopoint Components, we are proud to offer a full range of TMR sensors including analog and digital sensors, proximity, angle and rotation sensors and smart sensors for Arduino applications.
It is common to compare the TME devices to the traditional Hall effect sensors, as they are both compatible with the modern CMOS technology - the TMR however offers smaller package size (the RedRockTM series are some of the smallest magnetic sensors on the market), lower power consumption, 1000-times higher sensitivity and high thermal stability. If you are considering replacing your Hall effect sensors with the TMR sensors, please do not hesitate to contact us, our sales engineers are trained to provide support and help you find the best solution.

NVE AAT001-10E

The NVE AAT001-10E angle sensors use unique tunnelling magnetoresistance (TMR) elements for large signals and low power consumption. The sensor provides sine and cosine signals defining the angle of rotation, the outputs are proportional to the supply voltage of 5.5V (max) and peak-to-peak output voltages of 0.2V/V over a full rotation which are much larger than conventional sensor technologies. The AAT001-10E sensors from NVE consist of two half-bridges with a typical bridge resistance of 1.25MΩ for ultra low power applications in an ultraminiature TDFN6 package.

  • Surface-mount tunnelling magnetoresistance (TMR) angle sensor technology
  • Required applied magnetic field range from 30 Oe to 200Oe
  • Supply voltage of +5.5V
  • Peak to peak output signal 0.2V/V
  • Typical Device Resistance of 1.25MΩ
  • Microwatt power consumption
  • High output signal without amplification
  • Immune to airgap variations
  • Operates with as little as 30 Oersted field.
  • Sine and cosine and outputs
  • Operating temperature range of −40°C to +125°C
  • Ultraminiature TDFN6 package

The AAT001-10E sensor contains four sensing resistors at 90° intervals and 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 ATT001 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 AAT001-10E:

NVE AAT001-10E 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.

  • Operating temperature range −40°C to +125°C
  • Ultraminiature TDFN6 packages

The AAT003-10E 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 AAT003-10E:

NVE AAT003-10E 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.
