DM02系列 磁屏蔽材料 DM02 Series Magnetic shielding Materials
产品描述Product description
当磁场的频率很低（工频或1MHz 以下）时， 传统的屏蔽方法几乎没有作用。低频磁场的屏蔽是使用铁磁性材料将敏感器件包起来。磁屏蔽的作用是为磁场提供一条低磁阻的通路，使敏感器件周围的磁力线集中在屏蔽材料中，从而起到屏蔽的作用。
The traditional shielding method has little effect when the frequency of electromagnetic field below 1MHz,but we can wrap the sensitive devices with ferromagnetic materials to provide a low magnetic impedance path for the magnetic field, so that the magnetic lines around the sensitive devices are concentrated in the shielding material.
