Z-Pack HM-Zd is a high speed, differential connector system, which is compatible with the Z-PACK 2mm HM connector line. Z-PACK HM-Zd provides Z-PACK 2mm HM users with a migration path for serial switching applications from 3.125Gbps to 5.0Gpbs.

The Z-PACK HM-Zd connector system features a highly reliable dual beam conact system with fully encompassing grounds dedicated to each differential pair. In addition, the Z-PACK HM-Zd footprint is optimized for both routability and system performance with the use of 1.5mm x 2.5mm row to column grid. The connector design also features a robust mating interface with integral pre-alignment and polarization built into the mating interface.


  • Z-PACK HM-Zd is an extension of the Z-PACK 2mm HM product line
  • Designed specifically for high speed differential applications
  • A modular connector system with a standard module size of 25mm
  • Contact pitch is 1.5mm within a pair and 3.0mm pair to pair within a column; column-to-column pitch is 2.5mm
  • Card Pitch is less than 0.8 inch for 2 pair headers and 1.0 inch for 4 pair headers
  • Available in two versions:
    • 2 signal contact pairs per column (20 pairs per 25mm)compatible with 5 row Z-PACK 2mm HM
    • 4 signal contact pairs per column (40 pairs per 25mm) compatible with 8 row Z-PACK 2mm HM
  • Available in vertical press fit pin headers and right angle press fit receptacles
  • Optimized footprint for improved electrical performance and ease of routing channels on both daughter card and backplane
  • Pin headers and receptacle have the exact same footprint to simplify PC board layout
  • Designed to meet Telcordia requirements
