Circular Cable AssembliesCircular cable assemblies are an important category of electronics and electrical components in modern industry. These cables, commonly referred to as shields and chokes, are used as a way of connecting various instruments or devices together to provide protection from various environmental hazards such as electromagnetic interference (EMI) and radio frequency interference (RFI). In the past, the use of smaller cable and connector components was necessary to achieve optimum shielding and connection performance.In today’s electronics industry, circular cable assemblies are commonly used in a variety of applications. They include but are not limited to telecommunications, video equipment, medical instruments, aircraft, automotive, and many other areas. The circular cable assemblies are designed to replace short travels in the system, provide uniform coverage of components and instruments, and provide an efficient way of connecting and protecting components from environmental conditions. The typical use for circular cable assemblies includes cable shielding, ground loops, and bridging signals.Circular cable assemblies typically consist of a central body or central conductor, a center conductor contact, and a series of connectors on each end, as well as a number of inter-connecting strands of wire. The center conductor contact includes the splices, contact pins, and insulation material to join the location of the signal at one end, and the conductor of the other. The connectors can be made from various materials, depending on the requirement of the application.The working principle behind circular cable assemblies is based upon two principals - inductive shielding and radiating shielding. Inductive shielding is the type of shielding that is found on most types of containers and electronics. With Inductive shielding, the connection between the shielding conductor and its internal components is not a direct electrical contact; instead, the shields provide a barrier to electromagnetic and radio frequency interference. The exact performance depends upon the shielding material and the design of the cable assembly.Radiating shielding is the type of shielding that is used for high-power applications. Radiating shielding consists of a metal mesh shield which functions to surround and protect the cables from radiation. Radiating shielding also has very high levels of performance and is designed to meet the high tolerance of signal bandwidths.As a type of electrical component, circular cable assemblies are used on medical instruments for both internal and external wiring. Medical instruments can benefit from using circular cable assemblies because of the small diameter of the cable which allows for greater flexibility and protection against tearing and fraying. Additionally, the shield and choke on the cable provides protection against EMI and RFI.Circular cable assemblies are also used in aircraft and automotive applications. They can be used to provide shielding for communication lines as well as to route power and other signals. The shield on the cables acts like a vehicle for electrical energy and is used to transport high power levels, and to reduce the risk of shock.In industrial settings, circular cable assemblies are used to interface with various machines, systems and components in order to route, protect and monitor signals. Circular cable assemblies are also used to provide safety and interference protection. In automotive applications, they can provide grounding to the body and the system and make connections with numerous components.Circular cable assemblies provide the reliability and efficiency that is needed in many industrial, medical and automotive applications. They are an integral part of the constructions and renovation of modern equipment and facilities. Their use helps to maximize the efficiency and cost effectiveness when dealing with hazardous environments.
