Backplane connectors, otherwise known as edge connectors, are specialized components used to facilitate communication between the various electronic components of a computer system, such as the central processing unit, memory modules, and peripherals. The devices support and enable hot-swapping of multiple circuit boards, providing physical support and electrical connectivity for backplane connections. The 51939-101 is a coaxial cable-style connector used for signal and power lines in backplane systems. It is designed to provide reliable, secure connections allowing for interchangeability and flexibility.The 51939-101 connector has a standard rectangular shape, with two rows of pins on a Nickel-silver-plated steel body. It is designed to plug into female sockets on backplane assemblies. The device has two sets of contacts, one for each row of pins, which are divided into two distinctly different contact types. Two straight pins are used to supply power, while the remaining pins are used to carry signals. A key prevents misinsertion in the female socket and shields the contacts when the device is not mated.The 51939-101 connector is mainly used for the connection of power and signal lines in backplane assemblies. It is ideal for applications such as desktop computers, point-of-sale terminals, communications systems, and other devices that require reliable, secure connections in order to support and facilitate the transfer of data and power. Due to its large contact area, the connector is capable of carrying more current than other standard types, providing a heavy-duty connection. In addition, the device is rated for up to 5000 mating cycles, making it suitable for long-term use in high-traffic applications.The 51939-101 connector operates on two distinct principles. First, it relies on electrical connection for proper signal-level compatibility and to ensure electrical continuity between two mating connectors. Second, mechanical retention is used to keep the connector securely mated, while the key prevents the wrong type of connector from being inserted into a port. Both principles are combined to provide a strong and efficient connection within a backplane system.The 51939-101 connector offers several advantages over other types of backplane connectors. Its design for hot-swapping allows for easy installation and removal when needed. It also provides higher current-carrying capacity, improved signal integrity, better mating power retention, and a longer life cycle than other connectors. Furthermore, the device can be quickly and easily mounted to a backplane and is backwards-compatible with other industry-standard connectors. In short, the 51939-101 connector is an excellent choice for applications requiring secure, reliable connections with superior performance.In conclusion, the 51939-101 connector is a specialized component for use in backplane systems that requires no specialized tools or specialists for installation. It offers more current-carrying capacity than other standard connectors, and its design for hot-swapping makes it a great choice for applications in which ease of use is a key concern. Furthermore, the device\'s key ensures that the wrong type of connector cannot be inserted into a port, while its proven longevity and excellent signal integrity make it an ideal choice for long-term, heavy-duty applications.
