General Description

The AS5134 is a contactless magnetic rotary position sensor for accurate angular measurement over a full turn of 360 degrees and over an extended ambient temperature of -40°C to +150°C. The absolute angle measurement provides instant indication of the magnet’s angular position with a resolution of 8.5 bit = 360 positions per revolution via a serial output over the interface and as a pulse width modulated (PWM) 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:

  • Brushless DC motor position control
  • AC/DC motor position control
