Backplane Connectors - ARINC have come a long way since their inception. In the early days, they were limited to backplane applications for the communication of digital signals. Today, the applications have expanded to include use in Ethernet systems, as well as automotive, audio, consumer, industrial, medical, military and numerous other systems.

The 2-208972-8 connector is a right-angle design, with type 2 compliant contact connectors, and also meets the ARINC 600 series requirements. It offers robustness and reliable performance for backplane, I/O applications and midplane installations. The connectors are tested to meet the specifications of MIL-STD-454D and are constructed with a base contact support for superior signal integrity.

The 2-208972-8 is designed with 36- 1.5mm pins on a 2 row contact array, enabling it to support differential pairs and ground shielding. Due to its extremely low crosstalk, the connectors are well-suited for high-speed video and high speed data communication applications. It also features a blind mating design, which is a great benefit for high frequency applications where pre-terminated assemblies are used in the form of board-to-board, daughtercard, or mezzanine as well as a chassis to board assembly.

In terms of working principle, the 2-208972-8 connector is typically used for board-to-board applications. It is designed with a line frequency of 100MHz, and operates within the range of 125-150oC. The connector supports up to 4.0Amps per contact, and offers outstanding performance in terms of reduced crosstalk, EMI, vibration, and shock resistance.

The connector is fitted with a contact-to-mating area interface which eliminates skewing of signals and maintains precise alignment of contacts for secure contact mating. Additionally, the contact system is designed to withstand solder-flux build-up, while the relative-conductive plastic divides two circuit paths to reduce crosstalk.

The 2-208972-8 connector is compliant with RoHS requirements, and is provided with a 1000-cycle durability rating, which will ensures its re-usability in multiple applications. Overall, it is an ideal solution for reliable communication in high speed, edgecard, backplane and midplane applications.
