General Description

The AS5140H is a contactless magnetic rotary position sensor for accurate angular measurement over a full turn of 360° and over an extended ambient temperature range of -40°C to 150°C. The absolute angle measurement provides instant indication of the magnet’s angular position with a resolution of 0.35° = 1024 positions per revolution via a serial bit stream and as a PWM signal.

This product suits for the following applications:

  • Steering wheel position sensing
  • Headlight position control
  • Valve position sensing
