Backplane Connectors - Specialized

Backplane connectors are electrical connectors used to connect cards, boards, and other subassemblies in the backplane of a computer system. The backplane connectors are available in different form factors, materials, and configurations, and have various types of contact structures, such as solder points, pogo pins, spring fingers, and press fit pins. One of the most commonly used and widely recognized backplane connectors is the 6646769-1 application field and working principle.The 6646769-1 backplane connector is an ultra-high density (UHD) connector used for high speed, high frequency applications. The connector is designed to help reduce the number of necessary connectors on a PCB by combining multiple signals into a signal line. It is suitable for use with 2 to 4 row backplane designs, providing up to 16 differential pairs per linear inch. It features a 2.0 mm by 2.2 mm pitch, and is capable of speeds up to 28 Gbps.The 6646769-1 backplane connector is primarily used in a variety of networking, server, storage, and telecom applications. Its popularity is based on its reliability and high speed, which makes it suitable for high bandwidth applications. Additionally, its relatively small form factor and easy-to-use design make it a popular choice for a wide range of applications, from medical imaging to industrial automation and robotics.The 6646769-1 backplane connector features a unique two-piece design. The contact part consists of several fully isolating sockets, while the insulation part consists of a molded shell that encases the connector body. This design ensures that all pins are properly aligned and the contact resistance is uniform. Additionally, the insulation shell also serves as a strain relief, ensuring that the cable is not subjected to any unnecessary stress from connectors. The contacts are made with a proprietary gold-plated steel alloy, which provides maximum durability and electrical performance.The 6646769-1 backplane connector features a special “lock in” feature which ensures that it is properly and securely mated. This anti-vibration feature helps to reduce the possibility of disconnection, even during extreme vibration, due to its two-piece design. Additionally, the lock in feature allows up to 1600 mating/unmating cycles.The 6646769-1 backplane connector is cost-effective and easily accessible, making it an attractive solution for a variety of applications. It is also compliant with press-fit, backplane, and chip-on-board communications standards, making it an ideal solution for numerous applications. In addition, this connector is RoHS compliant, making it an environmentally friendly choice.In summary, the 6646769-1 backplane connector is an ultra-high density (UHD) connector designed for high speed, high frequency applications. It features a unique two-piece design with a special “lock in” feature, providing up to 1600 mating/unmating cycles. Its small form factor and easy-to-use design make it a popular choice for a wide range of applications, from medical imaging to industrial automation and robotics. Additionally, it is cost-effective and compliant with various communications standards, making it the ideal solution for numerous applications.
