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.

Features

  • Failure detection: Magnet placement + supply
  • Multiple devices serial read-out: Daisy chain
  • Detects movement of magnet in Z-axis
  • Contactless High Res. 360° Position Encoding
  • User-programmable zero position and settings
  • Serial communication interface (SSI)
  • 10-bit pulse width modulated (PWM) output
  • Quadrature A/B and Index output signal
  • Rational speeds up to 30,000 rpm

Benefits

  • Highest reliability and durability
  • Simple programming
  • Multiple interfaces
  • Ideal for motor applications
  • Failure diagnostics
  • Easy setup
  • Great flexibility at a huge application area
