Backplane connectors are a broad category of connectors, usually designed for and utilized in mounted circuit card assemblies in high density applications. Though known for their density, backplane connectors come in many shapes and sizes to accommodate a variety of cabling architectures and high-speed data signaling protocols. Among such connectors is the 51940-320LF, a specialized backplane connector designed for a very specific purpose and configuration in a backplane architecture.

The 51940-320LF is an optimized system for designing reliable dense backplane assemblies. It is designed to accommodate up to two daughter cards (or circuit cards) and two integrated transformer modules (also known as power transfer modules). This configuration is ideal for applications such as enterprise switches, backplanes, and such other equipment relying on dense, stable backplane architectures requiring both internal power distribution and power transfer between cards.

This connector is a four-row receptacle that slots into the main board. Each terminal has an individual contact connection to ensure greater stability and reliability. The receptacle has a bandwidth of 3.0GHz and supports both Surface Mount Technology (SMT) and Through Hole Mount Technology (THT) soldering and installation. The connector also has an integrated strain relief bar to help reduce the risk of crosstalk and enhance signal strength. The bars are designed to be installed with the connector to the main board and to the daughter cards, thereby providing further connection stability.

This backplane connector features a simplified design, with all four rows of pins coming pre-configured to suit the specific needs of the user. To further aid the ease of installation, the connectors support both soldering and blind mating installation. The blind mating design ensures that installation does not require any special equipment or tools. It also reduces the time and risk of errors during installation.

The 51940-320LF backplane connector also is designed to ensure safe and easy power transfer and distribution. It features a power interface contact, which allows the safe and efficient transfer of power between internal components and daughter cards. This contact features four gold-plated pads, which connect electrically and hold the alignment in place, ensuring a good connection between the daughter cards and the main board.

The 51940-320LF is designed for use in high-density applications such as enterprise switches, backplanes, and other specialized architectures. The advantage of using this connector is its ability to provide a stable, reliable connection between components and daughter boards, with a minimum of installation effort. This allows for a more efficient and economical assembly of complex devices and systems.
