Backplane Connectors - Specialized: 51939-056LF Application field and Working Principle

Backplane connectors are the necessary components for electric circuit boards. For instance, the 51939-056LF Series are specialized backplane connectors designed for high-speed data transfer in telecommunications and data storage applications. In this article, we will provide an overview of the 51939-056LF application field and working principle.

Application Field

The 51939-056LF Series are specialized backplane connectors developed specifically for high-speed data transfer in telecommunications and data storage applications. The cables in these connectors are designed to carry high bandwidths with low Insertion Loss. The connectors feature staggered contacts, a low profile, and low reflection. These features make them ideal for applications where size and performance are a concern.The 51939-056LF Series can be used both as an input/output resistive termination and a differential signal detector to improve signal integrity. Thanks to their low-profile design, they can be used in small and confined spaces. Therefore, these connectors can be effectively used in applications such as base stations, cellular communication systems, central offices, data centers, high-speed storage systems, industrial Ethernet systems, and many more.

Working Principle

The 51939-056LF Series work by providing an interface between two circuits by letting electrical current flow from one side to the other. This is possible because of the structure of the connectors. The connectors have four circuit pins arranged in a staggered configuration. Each circuit pin has its own insulation to prevent short circuits and interference from other devices.The pins of the connectors are also shaped into a narrow profile to reduce signal reflections and improve transmission speed. As the pins are connected to the board they form an electrical circuit that allows current to flow. Once the connections are established, the insertion loss is minimized and the signal integrity is improved.The 51939-056LF Series is also equipped with a ground clip, which allows the connector to be securely attached to a ground line. By providing a secure mechanical contact, the ground clip also acts to reduce inductance and improve signal integrity.

Conclusion

The 51939-056LF Series is designed to be used as backplane connectors in a variety of industrial and telecommunications applications. Thanks to their narrow profile and staggered contacts, they are capable of providing low inductance and improved signal integrity for applications that require high transmission speeds. Additionally, the ground clip provided in the 51939-056LF Series ensures a secure connection to a ground line. In conclusion, the 51939-056LF Series offer high performance and reliability for electrical circuit boards.
