FEATURES AND SPECIFICATIONS
Molex’s Impact backplane connector system pushes the speed and density envelope to meet the
growing demands of next generation telecommunication and data networking equipment
The Impact backplane connector system provides data
rates over 20 Gbps and superior signal density up to
80 differential pairs per inch. The Impact System’s
broad-edge-coupled technology enables low cross-talk
and high signal bandwidth while minimizing channel
performance variation across every differential pair
within the system.
Molex’s Impact System offers multiple compliant-pin
design options on both the daughtercard and backplane
connectors, providing customers ultimate flexibility
to optimize their designs for superior mechanical and
electrical performance. The Impact system’s mating
interface provides inline-staggered, bifurcated contacts
that provide 2 points of contact for long-term reliability
Features and Benefits

n
PCB routing flexibility provides simple 1.90 by
1.35mm (.075 by .053”) grid on both backplane
and daughtercard reduces PCB routing complexity
and costs
n
Two compliant-pin attach options provide customers
ultimate flexibility to optimize their designs for
superior mechanical and electrical performance
n
Inline staggered, bifurcated contact beams in
daughtercard interface for superior mating
performance with two points of contact for
long-term reliability and built-in ground-signal
sequencing
performance and built-in ground-signal sequencing.
This reduces the average mating force per connector
to improve the mechanical mating performance of
the system.
The Impact backplane connector system is designed for
traditional backplane and/or midplane architectures
to meet the growing demands of next-generation
telecommunication and data networking equipment
manufacturers. The Impact connector system is offered
in 3-, 4-, 5- and 6-pair versions, with a complete range
of guidance and power-solution options. For more
