General Description

The AS5040 is a 10-bit rotary position sensor (previously known as encoder) for absolute angular measurement and with an incremental 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 PWM output signal.


Magnets cannot be ordered at ams directly. Please find a list of recommended magnet suppliers.

This product suits for the following applications:

  • Motor speed and motion sensor
  • Replacement of optical magnetic position sensors
  • Commutation of brushless motors
  • Robotics
