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.
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.
Not Recommended for New Designs
ams-OSRAM AG does not recommend using AS5115 for new designs. A new product version is under development and will be announced soon.
Please contact your local sales representative for further information regarding available or planned replacement options.

This product suits for the following applications:
- Electronic power steering
- Contactless rotary switches
- General industrial applications
