Backplane connectors are an integral part of electronic systems and play a significant role in managing data flows. They transfer data signals between different components in a given system, forming the backbone of the computing system. When it comes to specialized backplane connectors, the 51939-223LF is one of the best in class. In this article, we will discuss its application field, working principle, and other salient features.

Application Field

This 51939-223LF connector has a broad application field as it is suitable for a variety of applications. It is primarily used in industrial automation, data communication systems, and computer systems. It is suitable for use in harsh environments due to its corrosion resistance and can operate efficiently even in temperature ranges between -65℃ to +125℃.

Working Principle

The 51939-223LF connector is a high-speed connector, with a frequency bandwidth of up to 3GHz. It contains three rows of sixty-six pins in a 0.025" pitch. This provides a secure and reliable connection between two components of the system at a very high speed of data transfer. It is designed specifically to ensure minimal cross-talk which helps preserve signal integrity and also to reduce radio frequency interference (RFI).

Other Salient Features

The 51939-223LF connector is designed to operate at a higher current load — up to 8.1 amps per contact — while providing excellent contact resistance and life expectancy in cyclic operations. It also has the ability to manage digital signals and analog signals over a wide bandwidth. The total number of contacts in the connector is 3822 with a maximum operating temperature of +125°C. This allows it to be used in a wide range of applications, including in equipment with high current and temperature requirements.

The 51939-223LF connector also offers superior performance and durability due to its die cast shell construction, high contact force, and gold plated contacts. The die cast shell provides a robust shield against environmental elements. The high contact force provides increased electrical contact and greater wear resistance for extended life. Lastly, the gold-plated contacts ensure the highest levels of connection reliability.

Conclusion

The 51939-223LF connector is designed for high-speed, high-reliability applications in industrial, data communication, and computer systems. Its broad application field and high performance features make it an ideal option for use in a variety of projects. It is also designed with corrosion resistance and temperature range capabilities, allowing it to provide reliable data transfers in harsh environmental conditions.
