Backplane connectors are a key link in the assembly of most data, communication and computer based systems. The 51940-520LF from TE Connectivity is an example of a specialized backplane connector. Designed to meet the stringent requirements of automotive, avionics, high-speed communication systems, computers, robotics and other industrial equipment, this device is able to provide reliable interconnects in the most challenging of environments. By understanding its application field and working principle, it can make a significant contribution to the assembly of a product.

Application Field

The 51940-520LF backplane connectors are specifically designed for use in applications where the high-speed transmission of data is required. Examples of this include automobiles, avionics and computers. With its ability to maintain signal integrity at speeds of up to 8 GHz, it is particularly suitable for applications which involve the transfer of high-bandwidth information, such as those in communication and data networking. The connector also features excellent mechanical stability, making it suitable for integration into devices and systems where vibration and shock is a concern.

Working Principle

The 51940-520LF backplane connectors operate on a two-row design. The first row of contacts is the signal contacts, which transfer data, while the second row is the power contacts, which supply necessary power to the device. The contact system is a pair of machined sockets which contain two rows of four contacts each. The contact system also includes a high-temperature solder solder cup which maintains mechanical stability during vibration, shock and thermal cycling.

The 51940-520LF backplane connector utilizes a specifically designed latch system which ensures a secure connection and maximum durability. A latch-locking mechanism engages the connector to the mating connector, creating a tight fit between the two. The latch-locking mechanism also eliminates the need for crimping or soldering, ensuring a secure connection without the need for external tools. The use of high-speed pressure contacts in the latching system provides a secure and reliable connection, as well as allowing for quick and easy assembly.

The 51940-520LF backplane connector also features a high-temperature sealed solder cup which provides protection against contact corrosion. In addition, the contacts are surface treated for excellent conductivity, ensuring a reliable and consistent connection. The contact system also includes a plating system for resistance to aggressive environments and high contact-wear capability.

Conclusion

The 51940-520LF backplane connector is an example of a specialized backplane connector designed to meet the requirements of a variety of specialist applications. It is able to maintain signal integrity at speeds of up to 8 GHz and features a secure latch locking mechanism. The contact system includes a high-temperature sealed solder cup to protect against contact corrosion, and the contact surfaces are surface treated for excellent conductivity. The 51940-520LF backplane connector is a reliable and durable connector which is able to provide reliable interconnects in the most challenging of environments.
