Backplane connectors are an essential component of many circuit boards and systems. They are made up of a usually standardized electric connection between two printed circuit boards (PCBs), also known as the backplane. The 51939-425LF is one such component, a specialized backplane connector typically used for digital signal and power applications. It’s a reliable, robust connection that provides a secure, repeatable connection for applications that require frequent changing and high speed performance.

The 51939-425LF is primarily designed for demanding, high speed digital applications. It uses a miniature, high-speed breakout connection system, which requires minimal space along the board to which it is connected. It features a robust mechanical connection, with a self-aligning contact system and solid-pin design that is compatible with 0.015″ and 0.020″ thick PCBs. The contact system is reliable, and ensures strong and secure connections. It’s also highly resilient to vibration and shock due to its cross-coupling contacts that prevent any movement of connections due to external stresses. This makes it ideal for medical, defense, and other applications where durability and reliability are paramount.

The 51939-425LF’s performance is further enhanced by its anti-EMI shielding. The connector’s internal geometry forms a Faraday shield that prevents any external EMI signals from interfering with the connection when compared to metallic contact pins. This makes it an ideal choice for applications where signal integrity and EMI protection are essential, such as audio/visual equipment, medical imaging, or even automotive components.

The 51939-425LF is also suitable for power applications due to its ability to handle up to 10A current per pin and up to 25A per row. This makes it a viable solution for a whole host of power applications.

The 51939-425LF’s working principle is fairly straightforward. It utilizes a simple plug-in connection technology, allowing the user to easily connect and disconnect boards without any complicated cabling or setups. Once connected, the connector’s spring-loaded contacts ensure a solid connection, with no loose pins or connections slipping out of place. This makes it a highly reliable and secure connection for a wide variety of applications.

The 51939-425LF is a reliable, robust, and versatile backplane connector ideal for a variety of applications. Its miniature size and high speed performance make it well-suited for digital applications, such as audio/visual equipment, medical imaging, automotive components, and more. Its anti-EMI shielding makes it an ideal choice for applications where signal integrity and EMI protection are paramount. Additionally, its ability to handle up to 10A current per pin and up to 25A per row makes it suitable for power applications. Finally, its plug-in connection technology provides a simple and secure way to connect and disconnect boards.
