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.
