IntroductionThe BK4ARN12079XY Circular Connectors - Backshells and Cable Clamps are widely used in numerous industries and applications that often require a tight seal between cables and connectors. The performance of these circular connectors is among the very best, helping to ensure no leaks, reduced cable fatigue and less operational risk. By familiarizing ourselves with this specific connector, we can gain insight into its application field and working principle. Application FieldThe circular connector BK4ARN12079XY can be used in a wide range of applications. These connectors are particularly popular in military and aerospace applications, where extreme environments and noise immunity require robust performance. Given the wide electrical insulation resistance, they are also suited for medical and medical device applications. When used in broadcast and hi-fi systems, these connectors are able to sustain adverse environmental conditions and provide excellent performance even in high-frequency applications. For industrial applications, the BK4ARN12079XY is particularly well suited for use in power supplies, voltage regulators, current and voltage protection systems, various control circuits, and other electrical equipment.Working PrincipleThe BK4ARN12079XY circular connectors are based on a clamp and fastener connection, which is a time-tested method of making secure, dependable connections. The cord is inserted between the clamp and fastener, forming a pair of reliable seals at the connection site. To help maintain these seals, the fastener is then tightened until it provides the necessary tension. Additionally, the entire assembly may be wrapped with a shielding tape to further protect the cables from environmental elements.The connector shell is equipped with an environmental protection grommet that both prevents dust and deformation from entering the connection sites, and acts as a strain relief for the cables, further ensuring a reliable seal. Additionally, the connectors come with an interior ground spring which helps the conductors maintain electrical continuity even under demanding conditions.ConclusionThe BK4ARN12079XY Circular Connectors - Backshells and Cable Clamps are reliable, versatile components that are suitable for a wide range of applications. They feature a clamp and fastener connection for a reliable, consistent seal, while the environmental protection grommet and interior ground spring work to ensure the conductors maintain electrical continuity, even in harsh conditions.
