General description

The AS5304 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 160 pulses per 4.0 mm pole pair length on the standardized quadrature output interface with an index pulse (=ABI-interface) with a maximum speed of 20m/s.

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:

  • Motor speed and motion control for off-axis applications
  • Replacement of linear and rotary optical sensor systems
  • Control of XYZ-tables
  • CNC machines
