V datasheete dost machruju s konkretnymi hodnotami indukcie atd., takze 
sa asi nie celkom da pouzit kazda podkova co je poruke.

Typically the magnet should be 6mm in diameter and
3mm in height. Magnetic materials such as rare earth
AlNiCo/SmCo5 or NdFeB are recommended.
The magnetic field strength perpendicular to the die
surface has to be in the range of ±45mT…±75mT (peak).
The magnet’s field strength should be verified using a
gauss-meter. The magnetic field Bv at a given distance,
along a concentric circle with a radius of 1.1mm (R1),
should be in the range of ±45mT…±75mT. (see Figure
15).
