BACKPLANE CONNECTORS - SPECIALIZED
The 2057739-1 is a specialized backplane connector. It is manufactured by Molex, and is designed for use in high-speed networking applications. The connector is available in both vertical and angled configurations, allowing the boarding system to be tailored to the particular application. This connector is rated for up to 2.00A, and is capable of transferring data at a rate of 5Gbps.

Application Field
The 2057739-1 is commonly used in applications such as Local Area Networks (LANs), High Speed Local Area Networks (HSLANS), Broadband Access Networks (BANs), and Asynchronous Transfer Mode (ATM) networks. It can also be used in storage area networks, direct memory access (DMA) systems, and Ethernet-based networks. This connector can be used with a variety of cabling systems, including stacking, daisy-chaining, and multi-level architectures.

Working Principle
The 2057739-1 has a four-position pin-out with a positioning slot at the center. This lets the connector fit into most backplane slots. The pins are numbered 1-4, and the positioning slot is numbered 5. The contacts are gold-plated, making them corrosion-resistant and highly conductive. The female contacts have two fingers that ensure maximum retention to the board frames. The blade-style contact interfaces have to be bent to align with the other mating contact and help maintain for connection integrity against shock and vibration.

The 2057739-1 is designed to provide reliable electrical and physical stability for networking applications that require high throughput and high data rates. Its four-position pin-out supports up to two A-B pairs, which allows for two differential pairs per connector. This allows for deeper networking configurations and higher data rates without sacrificing the electrical integrity of the connections. Its anti-vibration design and gold-plated contacts also ensures that noise is minimized and data transfer is reliable and secure.

Conclusion
The 2057739-1 is a specialized backplane connector that is suitable for a variety of high-speed networking applications. It is capable of transferring data at speeds up to 5Gbps and up to 2.0A. Its four-position pin-out allows for up to two differential pairs per connector, and its gold-plated contacts and anti-vibration design ensure reliable data transfer and minimal noise. This makes the 2057739-1 a reliable, high-speed connection option for applications that require high throughput and data rates.
