Backplane connectors are essential components for interconnecting printed circuit boards and powering equipment components. The type of backplane connectors used depends on the signalsrequired, the environment in which the equipment will be used and the physical size of the connector. While there are a variety of different types of connectors available, one specialized type is the 51721-10000404AA. This section will discuss the application fields and working principle of the 51721-10000404AA.

Application Fields

The 51721-10000404AA is a coaxial conenctor that is designed for use in military and aerospace applications. It is a hermetically sealed, high-frequency, high-speed connector which is capable of transmitting at frequencies up to 10GHz. This makes it particularly suitable for applications such as RF circuits, antennas, radio transmitters, receivers and amplifiers. As such, it is an ideal solution for aerospace and military applications where reliable, high speed interconnection is required.

The 51721-10000404AA is also suitable for use in harsh environmental conditions such as high-altitude, extreme temperature and radiation environments, making them an ideal solution for aerospace applications. Additionally, the connector has excellent vibration and shock resistance capabilities, making it suitable for harsh industrial or military equipment applications. The high-performance and reliable design of the 51721-10000404AA also make it ideal for use in commercial aircraft, satellites, launch vehicles and other high-stakes applications.

Working Principle

The 51721-10000404AA uses a High Frequency Interference (HFI) Design. This design utilises a combination of a 12-layer high-frequency power metal shell and a high-performance ceramic-filled PTFE insulation. This ensures an excellent connection, even at high frequencies up to 10GHz. The connector also uses precision-engineered brass contacts to ensure a reliable connection even in the most challenging environments.

The hermetically sealed design of the 51721-10000404AA allows it to be used in high radiation and extreme temperature environments, as well as resisting salt spray, oil and other elements without degrading the performance of the connector. The high-frequency performance of the connector also ensures it can be used in high-speed applications, with a low insertion loss of 0.1dB at 10GHz. Additionally, the connector features an operating temperature of -65C to +165C and an insertion/extraction cycle of 2000 times.

Conclusion

The 51721-10000404AA is a specialized backplane connector designed for military and aerospace applications. It utilises a HFI design with a 12-layer power metal shell and ceramic-filled PTFE insulation for a reliable connection even in the most demanding applications. The hermetically sealed design and high-frequency performance makes it suitable for use in high radiation and extreme temperature environments, as well as resisting salt spray, oil and other elements without degrading the performance. The 51721-10000404AA is therefore an ideal choice for use in commercial aircraft, satellites, launch vehicles and other high-stakes applications.
