The AS5145H 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 0.0879° = 4096 positions per revolution via a serial bit stream and as a PWM signal.

Key Features

  • Contactless absolute angle position measurement and motion sensing
  • User programmable zero position
  • Multiple interfaces (SSI, PWM)
  • Immune to external magnetic stray fields
