Backplane Connectors - Housings are connectors used to transmit high-speed signals through a backplane or via printed circuit boards (PCBs). The 120743-1 is a backplane connector that is designed to provide high density I/O connections of up to 8100 contacts across a backplane. It is designed to withstand high rates of vibration and shock, as well as exceptional thermal stability and high resistance to mechanical and electrical shock.The 120743-1 is engineered for a wide range of applications and system designs, and is commonly used in high speed computing, telecommunications, and aerospace industries. It offers enhanced shock and vibration performance through its robust construction, and low signal crosstalk when compared to other backplane connectors.The 120743-1 connector housing consists of two main components: the female connector, also referred to as the receptacle, and the male connector, also known as the plug. The female connector is mounted to the PCB, and the male connector is inserted into the female connector. The female connector has two rows of three-column contacts that are arranged in two columns. The three-column contacts are connected between the male and female connectors. The contacts also have some form of insulation, typically aluminum oxide material, to help reduce the risk of electrostatic discharge.The working principle of the 120743-1 is based on a mechanical connection between the connectors. When the male connector is inserted into the female connector, the pins on the two connectors align perfectly with each other. This ensures no data loss due to misalignment of pins. The two-row connector also makes it easier to route data through the backplane. Additionally, the contacts have a spring-loaded action. This helps the connectors remain securely coupled even if the connector is subjected to heavy vibration or shock.The 120743-1 is designed to provide a reliable signal and data transfer between two devices connected to each other across the backplane. The connector is capable of transmitting signals up to 8100 Mbps, making it ideal for applications that require high data transfer speeds. Additionally, the connector is designed to tolerate high temperatures and extreme environmental conditions, making it a suitable choice for applications in harsh environments.The 120743-1 is a robust connector designed for a wide range of applications but is most commonly used in high speed computing, telecommunications, and aerospace industries. This connector provides superior shock and vibration performance making it a reliable and stable connection for data transfer. Additionally, the two-row configuration of pins makes it easier to route signals and data across the connector which provides a superior connection for high-speed signal transfer.
