Data Sheet
14 Choosing the Proper Magnet
Typically the magnet should be 6mm in diameter and ≥2.5mm 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 B
a concentric circle with a radius of 1.1mm (R1), should be in the range of ±45mT…±75mT (see Figure 17).
