ARINC backplane connectors refer to electrical connectors that provide transmission of control signals and power between printed circuit boards and systems in high-speed, high-density applications. The most commonly used backplane connectors are the 206571-2 series. They offer robust performance, reliable operation and low insertion force requirements in a variety of systems requiring high performance interconnects.

The 206571-2 connector series is designed for applications where high bandwidth, high density and low weight need to be balanced. The components have been designed to meet the guidelines specified by the Airborne Electronic Hardware (AEH) standard that requires products used in airborne applications to perform reliably under extreme environmental conditions. The connectors are suitable for power applications with up to 11A/40Vdc and can also be used in combination with other power connectors suitable for up to 13A.

The 206571-2 offers a 50-pair, blind mating, pre-cable connection and axial guidance. This connector has a unique design which allows blind mate integration. It can be mounted horizontally or vertically and with or without backplane PCB. The unique feature of this connector is the thumbscrew which is used for mechanical detach and fastening when mating. It also has a dual side latching mechanism with surface mount capability. The contact barrels are made of gold-plated beryllium copper and are designed to ensure a stable and reliable connection.

Installation and maintenance of the 206571-2 backplane connection is easy and simplified by the use of keying and blind mating. The contacts are designed to accept board-edge to board-edge, board-edge to mid-board, and mid-board to mid-board mating configurations. This connector has a rated voltage of maximum 290 Vrms, signal up to 20GHz and current up to 11A per contact for power or signal, depending on the design requirements.

The 206571-2 is designed to provide a reliable and efficient interconnect for high-speed and high density applications. It is suitable for many aerospace, communication, automotive, consumer and industrial applications, including radio communication, satellite communication, antenna control systems, radar and electronic counter measure systems.

The working principle of the 206571-2 backplane connector relies on the connection between contact barrel and the corresponding contact point on the board side. The contact barrels are positioned on the boards or in the plastic housing interfaced with a metal retaining clip. The contact barrels are fitted to the corresponding contact point on the board side by inserting them into slots and secured with a retaining clip. When the connector is mated, the contact barrels are inserted and the transmitting signals get connected.

The 206571-2 connector series provide reliable performance, low insertion force and appropriate power/signal handling capacity in high performance applications. Compliant with the Airborne Electronic Hardware (AEH) standard, the connectors are capable of withstanding extreme environmental conditions and provide reliable connections in applications where high density and low weight must be balanced. With an easy installation and maintenance process, the 206571-2 can be used in a variety of applications such as radio communication, satellite communication, antenna control systems, radar and electronic counter measure systems, among others.
