Backplane Connectors - Specialized: 51787-001LF Application Field and Working PrincipleBackplane connectors are specialised electrical connectors designed primarily for interconnection of complex electronic systems, like computers, telecommunications and automated industrial systems. They are also used for connecting high power electronics, such as those used in some aircraft applications. Backplane connectors are grouped into two major categories based on how they direct electrical signals between the boards and components of an electronic system: card-edge and pin-mating.The 51787-001LF is a single row card-edge connector designed to attenuate and redirect the transmission of electrical signals between the boards and components of telecommunications systems, back planes, and other electronic equipment. Its application field includes communications, computing, instrumentation, consumer electronics, medical electronics, military and military ground related equipment, drones and other high performance applications.The 51787-001LF is designed to be a robust and high-performance multi-pin connector, designed for board-to-board and cable-to-board applications. It is compliant with RoHS, UL, IEC 61076-3-106, and other standards. The connector can be mated and unmated without the need for complicated wiring routing. The connector housing is constructed from a glass filled polyester thermoplastic which has excellent durability and resistance to shock and vibration.The 51787-001LF is designed with a low profile that simplifies its integration into tight spaces and can accommodate a wide range of contact heights and widths. It also offers a low insertion force for ease of use and a high-retention force for secure mating. Furthermore, the connector has an improved signal integrity which is achieved by utilizing a two-piece contact construction which ensures a consistent contact throughout its mating cycle providing a reliable connection between the boards or components of the electronic system.The working principle of the connector is based on a simple planar alignment system which guides a contact along a bi-directional path towards its other contact of the mate. This ensures that the contact elements of the connector are aligned for a reliable and secure connection. Additionally, the connector also features an anti-flip system that prevents the mating of the contacts in the wrong direction, keeping the connector safe and reliable.The 51787-001LF provides improved ingress protection from water, dust, and other contaminants, and it is metallized to protect the contact points from corrosion and increasing the life-span of the connector. As a card-edge connector, the 51787-001LF also allows for convenient re-sizability where a PCB’s length can be increased or decreased without having to redo the wiring.In conclusion, the 51787-001LF is a specialized backplane connector designed to attenuate and redirect the transmission of electrical signals between the boards and components of telecommunications systems, back planes, and other electronic equipment. Its robust construction, wide range of contact heights and widths, low insertion and retention forces, and ingress protection make it an ideal choice for many high performance and demanding applications.
