8.5 AS5311 Off-axis Rotary Applications
The AS5311 can also be used as an off-axis rotary encoder, as shown in Figure 11 . In such applications, the multi-pole magnetic strip is replaced
by a multi-pole magnetic ring. The ring can have radial or axial magnetization.

ring diameter [mm]
In off-axis rotary applications, very high angular resolutions are possible with the AS5311.
The number of steps per revolution increases linearly with ring diameter.
Due to the increasing number of pulses per revolution, the maximum speed decreases with increasing ring diameter.
Example: A magnetic ring with 41.7mm diameter has a resolution of 65536 steps per revolution (16-bit) and a maximum speed of 305 rpm.
