Backplane connectors are specialized electrical connectors for board-to-board applications. In this field, 51939-804LF connectors are one of the most common solutions. This tailored type of connectors offers reliable high-speed communication for multi-board backplane applications.

51939-804LF connectors feature two plug clips with two rows of 44 total contacts that make an electrical link between the two boards. Their design incorporates a six-pegged latching system to ensure that the connector remains fully mated once it is assembled. The contact spaces are staggered so that adjacent contacts form 180° to each other, which ensures that an interference-free connection is maintained once the connector is in place.

The application fields for a 51939-804LF connector include, but are not limited to: telecommunications, computers, automotive, video, broadcast, audio/visual equipment, medical devices, and test and measurement instrumentation. It is designed to support the dynamic demands of multi-board applications of various scales. High-speed differential signaling for data transmission up to 12.8 Gbps is also supported thanks to the use of an optional backplane link system.

How do these connectors work? Well, the 51939-804LF connectors integrate two “plug” clips that assist with the connection of a pair of mating backplanes. These two plug clips feature two rows of 44 contact pins. These pins are all aligned at precise distances and make an electrical link when they are inserted into a backplane receptacle. Additionally, the two plug clips have latching systems on each of them to ensure that the connector is securely mated with the backplane. Once the two plug clips are connected with the backplane, signal, data, and power contacts are established. This completes the connection between the two boards in a multi-board backplane system.

The 51939-804LF connectors are an ideal solution for any multi-board backplane application that requires backplane connections that are reliable and reliable high-speed. This specialized connector is designed to ensure that precise contact between two boards is made, providing a secure connection with minimal interference. The various application fields that a 51939-804LF connector can be used in make this type of connector an invaluable asset for many engineers looking to achieve a reliable connection between their boards.
