General Description

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.

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:

  • Motor position and motion sensor
  • Rotary knob for human machine interfaces
  • Position sensor for battery operated equipment
  • Robotics
