What is the role of the wire harness with magnetic ring? Some wire harness may have a magnetic ring wrapped in foam, which actually has some special functions.
1. The wire harness with magnetic ring can resist high-frequency interference, which can be either the outflow of the device itself or the inflow from the outside, and the energy of the high-frequency signal is absorbed by the ferrite core and converted into heat emission.
2. Absorbing magnetic ring is also called ferrite magnetic ring. It is usually used in the detachable magnetic ring. It is also a common anti-interference component in electronic circuits. It has a good effect of suppressing high-frequency noise. This is why magnetic rings are used in many electronic products.
But is it not good to have a wire harness without a magnetic ring? In fact, this is not the case. The use of the magnetic ring is more to prevent external high-frequency signal interference, and the use of a shielding layer can also achieve the effect of shielding high-frequency signal interference.
