Angular Sensors

By using a true angular measurement approach NXP®.s magneto-resistive (MR) angular sensors work accurately and reliably with no magnetic field strength variations. MR sensors operate virtually independent of magnet shifts and drifts due to lifetime, thermal influences or mechanical stress. They enable angular measurements with high accuracy by an excellent linearity and temperature drift behavior.

Our magnetoresistive angle sensors offer clear advantages over devices employing other sensing methods. MR sensors give an output signal virtually independent of magnet tolerances, magnet temperature coefficients, magnet-sensor distance and positioning tolerances.

Features

  • Extended temperature range
  • Accurate and reliable
  • Mechanical robustness, contactless principle
  • Wear-free operation
  • Accuracy independent of mechanical tolerances, magnetic drift with temperature or during life time
  • Less total cost of electro-mechanical system due to MR benefits
