Today, the electronics industry is developing rapidly. Radiation and interference are everywhere. In order to make information and data more accurate and fast, shielded cables are needed. What are the factors that affect the shielding effect in USB shielded cables?

The principle of electromagnetic shielding is to use the eddy current generated in the metal material with low resistivity to cancel the external electromagnetic wave in the high-frequency electromagnetic field; in the low-frequency electromagnetic field, the material with high magnetic permeability is used to limit the magnetic field line to the shielding body to prevent Diffusion into the shielded space; in special occasions, if it is required to have good shielding effect on both high frequency and low frequency electromagnetic fields, it is necessary to form a multilayer shield with different metal materials.

There are only two factors that affect the shielding effect: one is that the surface of the shield must be continuously energized, and the other is that no conductor can pass directly through the shield. As a professional manufacturer of shielded cable processing, Sinodec Industrial Co., ltd. determines whether it is necessary to add electromagnetic sealing gasket to the shielded wire according to the size of the electromagnetic wave wavelength during the use of the shielded cable of the customer to ensure the shielding effect of the shielded cable.

Sinodec Industrial Co., ltd. provide OEM service of USB shielded cable accroding to customer's requirement.
