... Detailed Description The AS5215 is a redundant rotary encoder sensor front end. 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 sine and cosine voltages. This approach gives maximum flexibility in system design can be directly integrated into existing architectures and optimized for various applications in terms of speed and accuracy ...

... Hall elements are located on the chip at a circle with a radius of 1mm. Since the difference between two opposite Hall sensors is measured, there will be no difference in signal amplitude when the magnet is perfectly centered or if the magnet is misaligned in any direction as long as all Hall elements stay within the linear range. www.austriamicrosystems.com/AS5215 BZ; 6mm magnet @ Z=1mm area of X- Y-misalignment from cen- ter: ± ...

... It is possible to get 40% or more signal amplitude by using thicker magnets. However, the gain in signal amplitude becomes less significant for h/ d ratios >~1.3. Therefore, the recommended magnet thickness for a 6mm diameter magnet is between 2.5 and ~8 mm. www.austriamicrosystems.com/AS5215 d= 6mm x h= 2.5mm ref. magnet: h ...

... Magnetic materials in the vicinity of the magnet will distort or weaken the magnetic field being picked up by the Hall elements and cause additional errors in the angular output of the sensor. Figure 8. Magnetic Field Lines in Air Figure 8 shows the ideal case with the magnet in air. No magnetic materials are anywhere nearby. www.austriamicrosystems.com/AS5215 0 (see Figure 5).

... Figure 10. Magnetic Field Lines in Iron Shaft If the magnet is mounted in a ferromagnetic material, such as iron, most of the field lines are attracted by the iron and flow inside the metal shaft (see Figure 10). The magnet is weakened substantially. This configuration should be avoided! www.austriamicrosystems.com/AS5215 Revision 1.9 (see Figure 9 ...

... Large diameter magnets (>6 mm Ø) have a wider linear range and allow a wider lateral misalignment. The flatter slope requires shorter axial distances. The linear range decreases with airgap; Best performance is achieved at shorter airgaps. The ideal vertical distance range can be determined by using magnetic range indicators provided by the encoder ICs. These indicators are named MagInc, MagDec, MagRngn, or similar, depending on product. www.austriamicrosystems.com/AS5215 Revision 1 ...
