Figure 3: Mounting and dimensions
A 8 x 2.5 mm diametric magneticed magnet must be placed over or under the AS5247 sensor,
and should be centered on the middle of the package with a tolerance of 0.5 mm. The airgap
between the magnet surface and the package should be maintained in the range 0.5 mm to 3
mm.
Recommendet nominal airgap for the 8 mm magnet = 2 mm.
Recommendet nominal airgap for the 6 mm magnet = 1.5 mm.
The magnet holder must not be ferromagnetic. Materials as brass, copper, aluminum, stainless
steel are the best choices to make this part.
