Introduction to 51939-357LF Connectors

51939-357LF is a special type of backplane connectors. This special connector is used primarily for applications where a very wide and complex signal types need to be connected between different parts of an electronic system. The 51939-357LF backplane connector has an extensive list of features, including a flexible mechanical design, integrated grounding hardware and enhanced electrical performance. It provides a full range of electrical and signal features through an array of advanced engineering and material solutions.

Construction and Design

The 51939-357LF backplane connector consists of an outer plug and an inner receptacle. The outer plug is made of a rugged polyester material that is lightweight and flexible yet has an impressive strength-to-weight ratio. An integrated spring-loaded retaining clip ensures that the plug stays securely connected while in use. The inner receptacle is machined from aluminum and is surrounded by an integrally-molded color-coded shielding. This shielding further protects the connector from environmental hazards.The 51939-357LF also features a particular type of contact design. This design consists of two tinned copper contacts, one contact being male and the other being female. These contacts are individually spaced along the connector body and feature a positive locking mechanism. This system reduces electrical impedance and improves electrical signal integrity. The 51939-357LF also includes integrated strain relief, which helps protect against electrical shorts.

Application Field and Working Principle

The 51939-357LF backplane connector has been designed for applications in a wide variety of industries, including automotive, data communication, industrial automation, medical, instrumentation, and networking. It is suitable for use in everything from telecommunications equipment to network servers.The working principle of the 51939-357LF connector is based on electrical signal transfer. By connecting an external device to the male contact at one end and the other device to the female contact at the other end, an electrical signal is allowed to travel between the two devices. This signal transfer is regulated by a system of conductive contacts along the connection. These contacts operate on the same principle as a common electrical switch, allowing the signal to complete a circuit before being transferred to the other side.

Concluding Thoughts

The 51939-357LF backplane connector is an invaluable device for applications where a high degree of flexibility and reliability is required. Its unique design allows it to bridge the gap between two different devices or systems, ensuring a safe and secure electrical connection. Although it may be slightly more costly than other types of connectors, the additional features and specifications that come with the 51939-357LF make it worth the investment.
