How to choose the appropriate Fakra cable model

When choosing a suitable Fakra cable model, the following aspects need to be considered:

Consider transmission performance

Frequency range: Different automotive electronic devices have different frequency requirements for signal transmission. For example, devices such as car radios and GPS navigators typically require the transmission of lower frequency signals, while cameras and millimeter wave radars in advanced driver assistance systems (ADAS) require the transmission of higher frequency signals.

Characteristic impedance: When selecting cables, it is important to ensure that their characteristic impedance matches the impedance of the connected equipment to ensure efficient signal transmission.

Consider physical characteristics

Cable size: Choose the appropriate cable size based on the installation space inside the car.

Flexibility: The wiring space inside the car is limited and the shape is complex, requiring cables to have good flexibility for easy bending and laying.

Consider environmental adaptability

Temperature requirements: When driving in different environmental conditions, the temperature in the engine compartment and other parts of the car is relatively high, while when used in cold regions, the ambient temperature may be very low. Therefore, it is necessary to choose cables that can adapt to the temperature range of the environment in which the car is located.

Waterproof, dustproof, and corrosion-resistant: Cars may encounter various harsh environmental conditions during driving, such as rain, dust, oil stains, and chemicals. Therefore, Fakra cables need to have good waterproof, dustproof, and corrosion-resistant properties to ensure long-term stable use.

Consider device compatibility

Fakra cables need to be compatible with the connected devices and connectors. Different types of Fakra connectors may be used for different automotive electronic devices. When selecting cables, ensure that they can be correctly connected to the connectors on the device and comply with relevant interface standards.
