The 6469081-1 is HM-Zd series Z-PACK HM-Zd Connector System is a high speed, differential connector system, which is compatible with the Z-PACK 2mm HM connector line. The Z-PACK HM-Zd connector provides Z-PACK 2mm HM connector users with a migration path for serial switching applications from 3.125 to 10+Gbps. The Z-PACK HM-Zd connector system features a highly reliable dual beam contact system with fully encompassing grounds dedicated to each differential pair. In addition, the Z-PACK HM-Zd connector footprint is optimized for both routability and system performance with the use of a 1.50 x 2.50mm (0.059 x 0.098 inch) row to column grid. The connector design features a robust mating interface with integral prealignment and polarization built into the mating interface.
