The AS5055A is a new version of the AS5055. It is a 12-bit rotary position sensor (previously known as encoder) for absolute angular measurement over a full turn of 360° based on contactless magnetic sensor technology. This device fits perfectly for on-axis applications where a simple 2-pole magnet rotates above or below the sensor IC. The absolute magnet angular position is measured with a resolution of 12 bit = 4096 positions per revolution and it is provided as a digital value on the serial interface (SPI).

Key Features

  • Contactless absolute angle position measurement
  • Very low standby current
  • Very small package
  • Immune to external magnetic stray fields

Key Benefits

  • Highest reliability and durability in harsh environments
  • Sensor for battery operated devices
  • Lower material cost (no magnetic shielding needed)
