... Detailed Description The AS5115 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 ...

... AS5115 Preliminary Data Sheet - Figure 3. 3D-Graph of Vertical Magnetic Field of a 6mm Cylindrical Magnet Bz [mT] X -displacement [mm] As shown in Figure 4 (grey zone), the 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 ...

... AS5115 Preliminary Data Sheet - For the 6mm magnet (shown in Figure 4), the linear range has a radius of 1.6mm, hence this magnet allows a radial misalignment of 0.5mm (1.6mm linear range radius; 1mm Hall array radius). Consequently, the larger the linear range, the more radial misalignment can be tolerated. By contrast, the slope of the linear range decreases with increasing magnet diameter, as the poles are further apart ...

... AS5115 Preliminary Data Sheet - 7.1.4 Angle Error vs Radial and Axial Misalignment The angle error is the deviation of the actual angle vs. the angle measured by the encoder. There are several factors in the chip itself that contribute to this error, mainly offset and gain matching of the amplifiers in the analog signal path. On the other hand, there is the nonlinearity of the signals coming from the Hall sensors, caused by misalignment of the magnet and imperfections in the magnetic material ...

... AS5115 Preliminary Data Sheet - the magnet is mounted in non-magnetic material, such as plastic or diamagnetic material, such as copper, the magnetic field distribution is not disturbed. Even paramagnetic material, such as aluminium may be used. The magnet may be mounted directly in the shaft Note: Stainless steel may also be used, but some grades are magnetic. Therefore, steel with magnetic grades should be avoided. ...

... AS5115 Preliminary Data Sheet - 7.1.6 Summary Small diameter magnets (<6mm Ø) have a shorter linear range and allow less lateral misalignment. The steeper slope allows larger axial distances. 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 ...
