General description

The AS5047D is a high-resolution rotary position sensor for fast absolute angle measurement over a full 360-degree range. This new position sensor is equipped with revolutionary integrated dynamic angle error compensation (DAEC™) with almost 0 latency and offers a robust design that suppresses the influence of any homogenous external stray magnetic field. A standard 4-wire SPI serial interface allows a host microcontroller to read 14-bit absolute angle position data from the AS5047D and to program non-volatile settings without a dedicated programmer. The resolution of the incremental ABI interface is programmable with a maximum resolution of 2000 steps / 500 pulses per revolution in decimal mode and 2048 steps / 512 pules per revolution in binary mode.

With two decades of magnetic sensor system know-how, we have broad experience in selecting the most suitable magnets. ams experts recommend the following magnet suppliers.

This product suits for the following applications:

  • Factory automation
  • Building automation
  • Robotics
  • PMSM (permanent magnet synchronous motor)
  • Stepper motors closed loop
  • Optical encoder replacement
