Backplane Connectors - Specialized

The 51720-10002004AALF (also known as the "Alfa Connector") is a specialized backplane connector for high data rate applications. This type of connector offers a wide variety of high performance contacts available in both male and female styles, as well as various levels of sophistication. The Alfa connector has proven to be a popular choice among backplane applications due to its high density capabilities, low voltage operation, and improved signal integrity.

Application Field

The 51720-10002004AALF backplane connector is mainly used in server and storage systems, as well as in communication equipment, instrumentation, industrial controls, medical devices, and other specialized equipment. This connector can also be found in the telecom and data communications industries, as well as in the aerospace and automotive industries. The design of this connector makes it a great fit for a wide range of board-to-board and board-to-cable applications.

The Alfa connector is well-suited for data transmission applications requiring high speed data rates, with up to 3400 Mbps of bi-directional bandwidth. This makes it an optimal choice for medical patients monitoring, as well as for high-end consumer electronics where low latency and high signal integrity are important. The Alfa connector is also suitable for high power applications, with up to 20A of continuous current per contact.

Working Principle

The Alfa connector is designed for positive contact engagement, with each contact pair achieving a fast and reliable connection. The connector contact operates in compression mode and is held in place by a spring-loaded actuator, providing a reliable connection which is unaffected by temperature fluctuations or mechanical shock. The physical properties of the connect also allows it to achieve a high degree of signal integrity, due to the low overall inductance of each contact.

The 51720-10002004AALF backplane connector also features power supply voltage compensation and built-in EMI/RFI shielding, so electrical noise generated by the connector does not interfere with signal transmission. This connector is rated for temperature extremes from -55°C (-67°F) to +125°C (+257°F) and is designed to meet industry standards such as EN 61000-6-3 for industrial immunity, relating to radiated emissions.

Conclusion

The 51720-10002004AALF backplane connector is designed for specialized applications such as high speed data communication, instrumentation, industrial controls, and power supply voltage applications. It offers reliable performance and excellent signal integrity even under extreme environmental conditions. Furthermore, it features built-in EMI/RFI shielding and low overall inductance, making it a popular choice among backplane applications.
