Backplane Connectors - Specialized

The 51940-084LF is one of the most common and versatile backplane connectors used in a variety of specialized applications. This small and lightweight but highly durable connector is suitable for a wide range of applications which require the transfer of power, signal, and other data signals with speeds up to 10 Gb/s.

Application Field

The 51940-084LF backplane connectors are mainly used in applications where there is a need to transfer power and data signals to and from an isolated set of components. The high performance and durability of the connectors make it suitable for use in military, aerospace, and other demanding applications. It is also used in aerospace, automotive, data communication, industrial automation, instrumentation, and medical applications.

Working Principle

The 51940-084LF backplane connectors use an advanced technology called the Low Frequency Interference Secure (LFIS) method. This technology enables the connectors to achieve reliable data transfer at high speeds and high levels of frequency and temperature stability.In order to better understand the working principle of the connectors, let us first look at the components of this connector. The 51940-084LF backplane connectors consists of two mating parts, the male header and the female socket. The male header has two rows of four contacts on each side. The male header contacts are secured by a spring loaded clip which provides a reliable latching connection. The female socket is a plug-in type that has a low insertion force and is designed to snap fit into the backplane.The two mating parts are connected by means of a pair of spring loaded contact balls embedded in a thermoplastic or rubber strain relief. When the male header is inserted into the female socket, the contact balls will form a reliable connection between the two with a low contact resistance, ensuring optimal data transmission. The contact force can be adjusted to suit the specific application, allowing for both high-frequency operation and high-speed operation.The LFIS technology used in the 51940-084LF connectors enables them to resist both low-frequency interference and high-frequency interference. The contact shape of the LFIS technology is designed to ensure reliable and consistent electrical performance, even under the harshest environmental conditions.

Conclusion

The 51940-084LF backplane connectors are a reliable and versatile choice for applications requiring the transfer of signal and power data. The LFIS technology ensures secure connections between the contacts, while the adjustable contact force provides reliable performance over a wide range of frequencies and temperatures. This small and lightweight connector is highly durable and suitable for a variety of applications.
