Backplane connectors are vital components in the electronic assembly industry, especially in large-scale system architectures such as servers and high-speed data centers. The 120954-4 backplane connector is a specialized type, designed specifically to simplify the engineering challenge of making interconnections between a wide variety of system boards. As the next generation of backplane connectors, it is optimized for high-speed data transfer and passing peak current through multiple contact pins.

Structure and Specifications

The 120954-4’s structure consists of a twin-beam pin system connected to a customized housing. This customized pin system has a pitch of 0.079 inch and a height of 0.364 inches, allowing it to be used in tightly packed, high-speed systems successfully. It features an exclusive insulating flange that connects between the twin beams which ensures fast engagement and disconnection between the pins and the board. The contact pins themselves are designed for maximum current passing and minimum signal degradation, with a maximum contact pressure of 168g. This affords unprecedented performance for operations involving data rates up to 5Gbps and transient currents up to 50A.

Applications and Working Principle

The 120954-4 is well-suited for board-to-board applications such as high-speed data centers, high-end servers, industrial automation products, avionics, and aerospace systems. Its twin-beam pin system provides a reliable and easy-to-use connection for making interconnections between cards and boards. The contact pins are designed to transfer data quickly and reliably, while also enabling the pins to pass high current through each point of contact. Through this combination of features, the 120954-4 provides secure and dependable communication for the most demanding applications.

In operation, the specialized housing slides the contact pins into the printed circuit board. Once in place, a latching mechanism locks the pins in place, maximizing contact pressure and reliability. In addition, the twin-beam design offers several electrostatic discharge and thermal flow paths, helping to safely dissipate any excess energy during operation. This ensures that any data signals transmitted or received through the board remain uncorrupted.

Conclusion

The 120954-4 backplane connector is an all-in-one solution for a wide variety of board-to-board applications demanding high-speed data transfer and up to 50A transient current. With a specialized housing design and twin-beam pin system, this connector provides reliable operation, while also affording superior signal integrity and thermal management. This makes the 120954-4 the perfect choice for applications requiring the utmost in board-to-board signal and power integrity.
