AS5030 Rotary Sensor

8-bit rotary position sensor with digital angle (interface) and PWM output

Buy Now Order Sample

The AS5030 is an 8-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 and the zero position can be programmed into the device. The absolute magnet angular position is measured with a resolution of 8 bit = 256 positions per revolution and is provided as a digital value on the serial interface (SSI) and on the PWM output signal. 

Key Features

  • Contactless absolute angle position measurement and motion sensing
  • User programmable zero position
  • Power Down Mode and Fast Startup
  • Immune to external magnetic stray fields

Key Benefits

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