What Is a FAKRA Cable?
A FAKRA cable is a specialized type of coaxial cable connector that is widely used in automotive electronics for connecting various devices. It is designed to maintain high-quality signal transmission while preventing electromagnetic interference, crucial for the reliable operation of automotive electronic systems.
The design of a FAKRA cable includes a metal shell and a resin housing that together secure the connection between the center and shield conductors of a coaxial cable. The metal shell is instrumental in forming an air layer around the conductors, which is key to shielding the signal transmission from external electromagnetic wave interference. The resin housing provides physical protection for the cable, ensuring durability and facilitating easy connection to devices.
FAKRA cables follow the fundamental principles of coaxial cable technology, utilizing an electromagnetic field between the center and shield conductors for signal transmission. They are essential in a variety of automotive applications, including in-vehicle navigation systems, audio systems, cameras, telematics, and advanced driver-assistance systems (ADAS). Their design features, including leakage prevention, durability, and ease of use, make them particularly suited to the demanding environments of automotive electronics.
