Systems
Two-Piece Backplanes
2mm Hard Metric
8+2 Connectors
Description:
Modular, high-density, two-piece backplane connection system
Typical Applications:
Servers
Switches
Routers
Add/drop multiplexers
Benefits/Features:
Industry Standard . . Meets IEC 61076-4-101 performance requirements and extends mounting, mating and other specifications from the 5+2 series.
Versatility . . . . . . . . Configurations similar to the 5+2 series allow mix-and-match to create solutions to complex I/O requirements.
Three mating length pins allow thousands of early mate, last break options and reduced mating force.
Integrated shielding available to minimize EMI.
Extended tails available for through the backplane I/O.
mates-last, breaks-first
awkward?
Flexible code-key indexing for user-defined slot discrimination.
Reliability . . . . . . . . Generous lead-in allows self-alignment for blind mating.
Minimum contact wipe of 2mm for all pin lengths.
