8.1 Magnetization
The AS5311 accepts magnetic multi-pole strip or ring magnets with a pole length of 1.0mm. Recommended magnet materials include plastic or
rubber bonded ferrite or Neodymium magnets.
It is not recommended to use the AS5311 with other pole lengths as this will create additional non-linearities.

errors (see Electrical System Specifications on page 8) . For example, when using a multi-pole magnet with 1.2mm pole length instead of 1.0mm,
the AS5311 will provide 1024 incremental steps or 4096 absolute positions over 2.4mm, but with an additional linearity error of up to 50μm.
The curvature of ring magnets may cause linearity errors as well due to the fact that the Hall array on the chip is a straight line while the poles on
the multi-pole ring are curved. These errors decrease with increasing ring diameter. It is therefore recommended to keep the ring diameter
measured at the location of the Hall array at 20mm or higher.
8.2 Position of the Index Pulse
An index pulse is generated when the North and South poles are placed over the Hall array as shown in Figure 14 .
The incremental output count increases when the magnet is moving to the left, facing the chip with pin#1 at the lower left corner (see Figure 14 -
top drawing). At the same time, the absolute position value increases. Likewise, the position value decreases when the magnet is moved in the
opposite direction.
