Introduction to the anti-interference performance of FAKRA cables

The anti-interference performance of FAKRA cable is excellent, mainly due to its structural design and material characteristics as follows:

Double layer shielding structure: FAKRA cables typically use a double-layer shielding layer composed of aluminum foil and woven mesh. Aluminum foil can provide good high-frequency shielding effect, effectively blocking the interference of high-frequency electromagnetic waves; The woven mesh has a good suppression effect on low-frequency interference and enhances the mechanical strength of the cable. This double-layer shielding structure can provide efficient electromagnetic shielding over a wide frequency range, effectively suppressing low-frequency interference from car radios, engine ignition systems, and high-frequency interference from mobile phone signals, wireless charging devices, etc.

The high conductivity of shielding materials: The aluminum foil and woven mesh materials that make up the shielding layer have high conductivity and can guide the induced currents generated by external electromagnetic interference to the ground, thereby avoiding these currents from generating interference signals inside the cable. At the same time, highly conductive materials can also reduce the leakage of electromagnetic fields generated by internal signals to the outside, prevent interference with other electronic devices in the surrounding area, and achieve good electromagnetic compatibility.

High insulation performance of insulation materials: The insulation materials used in FAKRA cables have high insulation resistance and low dielectric constant, which can effectively isolate internal conductors from the external environment, reduce leakage and coupling during signal transmission, and minimize the impact of external interference on signals. Even in complex electromagnetic environments, signal integrity and accuracy can be guaranteed.

Good grounding design: FAKRA cable connectors are usually designed with dedicated grounding pins, which can ensure a good connection between the cable and the grounding system of the equipment when installed in cars and other devices, forming a complete grounding circuit. This can quickly guide the interference current induced on the shielding layer into the ground, thereby improving the anti-interference ability of the cable.
