Backplane connectors are a type of hardware component used to carry data, power, and control signals to digital electronics in a variety of applications. The 51939-043LF is a specialized backplane connector that is designed to provide reliable, high-speed connectivity between several components in modern computing applications. This article will discuss the applications and workings of the 51939-043LF backplane connector.

Applications of 51939-043LF

The 51939-043LF is a vertical connector designed to be mounted on a backplane board for interconnecting several components and subsystems. This type of connector can be used in applications requiring a higher number of contacts, including power, Ethernet, PCI Express, and SATA for data and control signaling. Its flexible design minimizes the need for additional cabling and system complexity. The 51939-043LF is well-suited for use in servers, storage systems, communications equipment, and consumer electronic applications.

Design and Working Principle of 51939-043LF

The 51939-043LF is an 8-position connector that utilizes a dual-row mating system. It is made from a high-strength plastic composite and has a set of metal contacts to create a reliable connection. The connector is rated to 500V, 8A, and meets UL 94V-0 flammability requirements. The pins are gold-plated for extra reliability and corrosion resistance. The 51939-043LF is designed to fit on 0.100″ pitch backplanes and can handle speeds up to 5 Gbps.

The dual-row mating system of the 51939-043LF is designed for precise alignment of the plug and receptacle connections. The plug is inserted into the mating cavity of the receptacle and the pins in the receptacle are received in the correct sequence. The pins in the plug are then aligned with the correct contact points in the receptacle and the plug is pushed in to create the connection. When the plug is fully inserted, it is held in place by a latching mechanism. This ensures that the connection is secure and reliable.

The electric connection between the plug and the receptacle is established when the pins of the plug are correctly aligned with the contact points in the receptacle. The contact points in the receptacle are connected to circuits in the backplane, which in turn are connected to other components or subsystems. The electrical signals transmitted through the backplane are then transmitted to the required destination through the plug and the receptacle. This allows for the transmission of data, power, and control signals between components in a system.

Conclusion

The 51939-043LF is a specialized backplane connector that is designed to offer a reliable, high-speed connection for modern computing applications. It is capable of transmitting data, power, and control signals between components in a system and is well-suited for use in servers, storage systems, communications equipment, and consumer electronic applications. The connector utilizes a dual-row mating system for precise alignment and is rated to 500V and 8A. It has gold-plated pins for extra reliability and corrosion resistance and is rated for operation at speeds up to 5 Gbps.
