FEATURES & BENEFITS
0.8mm double-row contact pitch conserves printed circuit board space
Vast range of sizes and stack heights support diverse electronic packaging schemes
• 40 to 200 position sizes in 20 position increments
• 5mm to 16mm stack heights in 1mm increments
Choice of gold-based and palladium-based platings provide protection in different
environments and applications
Tapered PCB locator pegs increase the ease and accuracy of hand assembly
Blade-on-beam contacts allow peeling for safer, easier un-mating
Tape and Reel packaging supports high speed automated assembly
Optimize from Gen.2 to Gen.3 high speed performance on some stack heights
Fully inter-matable with similar competitive connectors
PLUS
Optimized "blade-on-beam" contact mating maximizes connection integrity
• Early receptacle contact point increases mating wipe and allows early
engagement/late disengagement
• Precision-tapered contacts control mating stress while providing reliable, high
normal force
• Coined contact tips assure smooth, safe wiping action during connector mating
• Connector polarization, generous lead-in angles and precise contact positioning
ensure precise mating alignment and reliability

DESCRIPTION
Versatile, high density
parallel-board-to-board connector
system offers twelve PCB stack
heights in nine sizes up to two
hundred positions.
Stack height flexibility supports
evolving designs and emerging
mechanical requirements with a
common mating interface.
Special housing and blade-on-beam
terminal features provide easy PCB
assembly, worry-free mating and
long-term reliability.
