Working alongside your design team from the earliest stage, we help you select the right part for the application and, where a standard part will not do, develop customised components with our manufacturing partners such as lead length, termination and package size.
The NVE AAT101-10E angle sensors use unique tunnelling magnetoresistance (TMR) elements for large signals and low power consumption. This is a full-bridge version of the half-bridge AAT001 angle sensor, the full-bridge configuration provides two differential outputs for easier interface in certain applications, twice as much signal and less supply voltage or temperature dependence. The AAT001 sensors from NVE provide 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 typical device resistance of 625KΩ enables low power consumption and is ideal for battery-powered applications.
The AAT101-10E 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 ATT series include:
The below table gives the full specifications of the NVE AAT angle sensor series including the AAT101-10E:
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.
