Description:
Modular
two-piece
backplane connection system
Typical Applications:
Servers
Switches
Routers
Add/drop
multiplexers
Benefits/Features:
Industry Standard . . . . . Meets IEC 61076-4-104 specification identifying mounting, mating, and performance requirements.
Versatility . . . . . . . . . . . Standard "block" sizes allow mix-and-match to create simple modular solutions.
5-row versions are available for increased line/inch density.
Multiple length pins allow virtually unlimited variations of EMLB (Early Mate, Last Break) and reduced mating force.
Solder-tail and press-fit versions are available and intermatable.
Reliability . . . . . . . . . . . Generous lead-in allows self-alignment for blind mating.
Several gold plating options are available for improved reliability.
