Backplane Connectors - Specialized: 51939-557LF Application Field and Working Principle

Backplane connectors play a vital role in improving the transmission performance of electronic devices. One such type of backplane connectors is the 51939-557LF connector, a special type of receptacle designed for making high-density connections between devices. Such connectors are regularly seen in the field of medical electronics, storage systems, telecom and computing.The 51939-557LF is a 2.00mm pitch, 36-pin receptacle connection that provides superior electrical performance and exceptional pressure protection. It comes with two rows of mechanical wall pins with 36-positions that are connected in series from one side to the other. Furthermore, it comes with press-fit technology which securely locks each connection point in an alternate fashion from one side to another. This creates an improved connection as the data transmission increases the intensity and stability of power delivery. Moreover, this specialized backplane connector has forty five-degree rotated pins which ensures reliable connection even when there\'s a misalignment between the receptacles and headers. Additionally, the 51939-557LF comes with multi-coaxial screw-locks on top with three adjustable latch positions for increased protection.The primary working principle of the 51939-557LF is that it helps create a connection between the backplane of a device and the other components on the board. It does this by being able to transfer energy or signals from one component to another, and it does this by using pins and sockets. The pins are configured in two rows so that the connection is more robust and reliable.Overall, the 51939-557LF is a superior quality backplane connector with excellent electrical properties and exceptional pressure protection. It offers high performance and reliable connections due to its 40-degree rotational pins and multi-coaxial screw-locks. The 51939-557LF is best suited for applications requiring high-density connections and is particularly popular in medical electronics, storage systems, telecom and computing markets.
