How to choose a suitable FAKRA coaxial cable?

When choosing a suitable FAKRA coaxial cable, the following key factors need to be considered:

Electrical performance

Characteristic impedance: The appropriate characteristic impedance should be selected based on the specific signal type and transmission requirements of the application.

Frequency response: If used for high-frequency signal transmission, such as 5G communication or satellite navigation, cables with a wide frequency response range, low loss, and stable transmission performance at higher frequencies should be selected to ensure signal integrity and accuracy.

Mechanical properties

Cable diameter and weight: Considering the interior space layout and wiring requirements, choose cables with appropriate diameter and light weight to save space and reduce the overall weight of the vehicle.

Flexibility and bending resistance: The wiring environment inside a car is complex, requiring cables to have good flexibility and bending resistance in order to be able to be smoothly wired during installation and withstand vibrations and bumps during vehicle operation.

Mechanical strength: Cables should have sufficient mechanical strength to resist external forces such as tension, compression, and wear, ensuring reliable operation throughout the entire service life of the vehicle.

Environmental adaptability

Temperature range: Cars may operate in various environmental temperatures, so it is important to choose cables that can maintain stable performance within the temperature range of the car's environment.

Waterproof, dustproof, and corrosion-resistant: If cables may be exposed to damp, dusty, or corrosive substances, such as outside the vehicle or inside the engine compartment, it is necessary to choose cables with good waterproof, dustproof, and corrosion-resistant performance to prevent cable performance degradation or damage due to environmental factors.

Interface type and compatibility

Interface type: Select the corresponding FAKRA coaxial cable interface based on the interface type of the onboard equipment to ensure that the cable and equipment can be connected correctly.

Compatibility: Ensure that the selected cables have good compatibility with other devices and cables in the vehicle system, avoiding signal interference or mismatches.

When selecting suitable FAKRA coaxial cables, it is necessary to comprehensively consider the above factors and make reasonable choices based on specific vehicle application scenarios and needs to ensure that the cables can meet the performance requirements of the vehicle and maintain stability and reliability in long-term use.
