General Description

The AS5311 is an incremental position sensor for linear and rotary off-axis applications based on contactless magnetic sensor technology. To measure position and motion a multi-pole magnet strip or ring has to be used. There are 4096 pulses (12-bit) per 2.0 mm pole pair length on the standardized quadrature output interface with an index pulse (=ABI-interface) with a maximum speed of 650mm/s.

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 control for off-axis applications
  • Replacement of linear and rotary optical sensor systems
  • Control of XYZ-tables
  • Robotic systems
