Backplane connectors play an integral role in the development of computers and other field applications. They provide a secure interconnection between boards and devices, facilitating data and power transfer. The 51940-276LF is a specialized backplane connector, designed for applications requiring high-speed signaling. It is often used in telecommunications, industrial automation, and in 5G deployments.

Key features

The 51940-276LF offers a variety of features which provide engineers with flexibility to meet their unique application needs. These include:

• 30D bus and 5 transmission lanes allowing for up to 8 digital signals;
• space saving kit is available;
• forged cavity-like contacts provide excellent signal density and PCB layout flexibility.

Application field

The 51940-276LF backplane connector is designed for the telecommunications and industrial automation fields. In these, its high-speed transmission capabilities make it ideal for 5G deployments. With an integrated signal rate of up to 8.5Gbps per lane, the connector is suitable for high-speed applications such as the transfer of fiber links, high speed I/O and ultra-high-speed memory.

The 51940-276LF is also specifically suited to systems requiring noise immunity. Its pressure contact pins eliminate the need for a gasket, which can act as a weak point against mid-frequencies noise, meaning that the connector can maintain signal integrity even in demanding environments.

Working principle

The 51940-276LF is a specialized backplane connector with a unique design. It combines conventional, cavity-like contacts and wire shield to provide superior transmission of digital data. With single-piece connectors, the signal integrity is improved through shorter traces. This design also provides excellent flexibility when it comes to PCB layout while maintaining a high signal density.

The connector’s high-speed transmission capabilities are provided by the 30D bus structure. This allows for up to 8 digital signals, each one with a signal rate of up to 8.5Gbps. This guarantees reliable, fast transmission of data and power even in the most demanding applications.

Conclusion

The 51940-276LF is a specialized backplane connector with excellent signal density and a high-speed transmission rate. It is ideally suited to the telecommunications and industrial automation fields, particularly for 5G deployments. By using a combination of traditional contacts and wire shield combined with a 30D bus, it provides a reliable and efficient connection between boards and devices, making it an ideal choice for many applications.
