Molex VHDM H-Series Backplane Connector System

Molex VHDM® (Very High Density Metric) H-Series Backplane Connector System is designed for applications with very high interconnect density and high-speed signal integrity requirements. The VHDM H-Series Backplane Connector System achieves data rates up to 6.25Gbps on an installed base and enables system upgrades without costly architecture redesigns. With a mating interface and envelope identical to earlier series, the VHDM H-Series is fully backwards compatible with existing VHDM slots. Using the Molex VHDM H-Series Backplane Connector System, designers can prolong the life of existing platforms, minimize development costs, and accelerate the speed higher-performance applications to market. The signal portion of the Molex VHDM H-Series Backplane Connector System features modular construction with 10 columns or 25 columns in either 6 rows or 8 rows. The metal stiffener in the daughter card connector can join signal wafers, power modules, and guidance modules to make one continuous connector with a maximum length of 300mm. The mating guide features on the metal pins and key slots provide excellent guidance for large PCBs and eliminate the possibility of insertion of a daughter card into the wrong slot.
