Magnetoresistive angle sensors offer clear advantages over devices employing other sensing methods

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. Achieving high accuracy and performance, these sensors are ideal for a variety of demanding automotive and industrial applications.

Key benefits

  • Accurate and reliable
  • Mechanical robustness, contactless principle
  • Wear-free operation
  • Accuracy independent of mechanical tolerances, magnetic drift with temperature or during life time
  • Extended temperature range

Key applications

  • Throttle and pedal positioning and headlight alignment
  • Steering wheel positioning, torsion
  • Chassis height
  • Seat positioning
  • Driverless transport-systems

Descriptive summary

The new KMA200 sensor system combines the sensor-head and the conditioning IC in a special multi-chip package. Furthermore each KMA200 is individually pre-calibrated and the system is user programmable for application-oriented output characteristics. Possessing different sensitivity, our KMZ41 and KMZ43 angle sensors are designed to work with the UZZ900x conditioning ICs, which provide either analog or 13-bit SPI interfacing.
