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.

Descriptive summary
Achieving high accuracy and performance, our angular sensors are ideal for a variety of demanding automotive applications. NXP provide cost-effective sensor solutions which help to meet tough emission targets. Ideal for high precision angle measurement applications, the sensor systems of the KMA200 family combine the MR sensor-head and the signal conditioning IC in a special multi-chip package. Furthermore each device is pre-calibrated and can be programmed for application specific output characteristics with the sinusoidal raw output signals externally processed according to the individual application requirements.
