Non-Contact Angular Position Sensor

    • Based on electronic compass technology
    • Features a magneto-resistive, two-axis magnetic sensor
    • Robust, completely sealed electronics
    • 1° resolution
    • Instant response time
    • Flexible compact design
    • A superior replacement for potentiometers
    • A sensor for the harshest environment
    • It’s ideal for any application in a harsh environment, including:
      • Chassis
      • Steering
      • Power train

Compass Sensor

    • Based on magneto-resistive technology
    • Compensates for varying magnetic fields within the vehicle
    • Exclusive Continuous Cal™ algorithm enables the compass to recalibrate itself continuously as it operates
    • Performs as either stand-alone device communicating on the vehicle's bus or integrated within a local display
    • Valuable features on any vehicle

Humidity Sensor

Most cars today maintain an inaccurate comfort zone based solely on temperature. The Magna Donnelly humidity sensor:

    • Measures both humidity and temperature
    • Feeds the vehicle’s climate control system the data to keep all occupants in the true comfort zone
    • Allows for more efficient operation of the air conditioner––crucial to fuel efficiency
