The Best Combination
NVE AngleSensors combine ultraminiature size, low power, high sensitivity, and high accuracy to make world class angle sensors that blow the competition away. No competitive part matches the versatility NVE Angle Sensors.

Low Power
NVE offers micropower angle sensors, and the ASR002 Smart TMR Angle Sensor offers nearly one-fourth the power consumption of TDK and AKM's competitive digitally integrated sensors.NVE's high impedance AAT009 consumes 600 times less power than analog sensors from ALPS and TDK.

High Sensitivity
When it comes to sensitivity, NVE Angle Sensors are in a class of their own. With accurate operation fields as low as 1.5 mT, NVE sensors are more than 10 times more sensitive than competitors.

High sensitivity means:
  • Larger airgaps and airgap tolerance
  • Excellent accuracy with cheap ferrite magnets
  • Work in off-axis configurations: Off-Axis-Angle-Sensing.pdf

Ultraminiature
NVE Angle Sensors come in tiny 2.5 mm x 2.5 mm TDFN6 packages, which take up less board space than TDK and AKM sensors. ALPS offers an angle sensor in a smaller package, but it consumes 600 times more power and doesn't even work to 125°C.

Practical Accuracy
NVE Angle Sensors have conservative accuracy specifications that cover all sources of error. Competitor parts inflate their accuracy specification by spreading out error terms and leave you to figure it out. You won't notice a difference in accuracy between NVE and TDK angle sensors, but you will notice the increased versatility due to NVE's higher sensitivity, lower power, and smaller size. AKM offers a reasonable 1.5° accuracy, but it consumes a jaw-dropping 110 mW, making it extremely costly for most applications.
