The AS5043 is a 10-bit rotary position sensor (previously known as encoder) for absolute angular measurement and with a programmable analog output 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 10 bit = 1024 positions per revolution and it is provided as a digital value on the serial interface (SSI) and on the analog output signal. 

Key Features

  • Contactless absolute angle position measurement
  • User programmable zero position
  • Diagnostic modes for magnet detection and power supply loss
  • Immune to external magnetic stray fields

Key Benefits

  • Highest reliability and durability in harsh environments
  • Great flexibility during assembly
  • Operation safety
  • Lower material cost (no magnetic shielding needed)
