General Description

The AS5115 is a contactless rotary position sensor for accurate angular measurement over a full turn of 360° and over an extended ambient temperature of -40°C to +150°C. Based on an integrated Hall element array the angular position of a simple two-pole magnet is translated into analog output voltages. The angle information is provided by means of buffered sine and consine voltages via a SSI Interface.

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

This product suits for the following applications:

  • Electronic power steering
  • Contactless rotary switches
  • General industrial applications
