Key Features & Advantage:

Anti-Misinsertion Shrouded Design: Built with a protective plastic wall (shroud) around the pins that prevents dynamic mating errors, protects contacts from bending, and ensures correct polarization.
Micro-Pitch Space Efficiency: 1.27mm miniature pitch provides an ultra-dense interconnection layout, drastically reducing overall PCB space requirements without compromising signal integrity.
Optimized High-Temp Durability: Molded from premium PBT, NL6T, or LCP materials (UL 94V-0 rated), rendering the connector highly resilient against standard lead-free wave and reflow soldering.
