Key Features & Advantage:

Double-Row High-Density Interconnect: The dual-row configuration allows for maximum signal density in a compact 2.0mm pitch, optimizing space on advanced PCBs.
Innovative Bottom Contact Design: Tailored for bottom-entry PCB layouts, ensuring clean, hidden, and stable board-to-board mating from beneath.
Enhanced Electrical Performance: Supports up to 2.0 Amperes of current rating with an increased dielectric withstanding voltage of 500V AC, perfect for demanding power and signal distribution.
Premium Material & High Heat Resistance: Features high-grade insulating plastics (LCP/NL6T/PBT, UL 94V-0) capable of enduring continuous high temperatures during standard SMT reflow soldering processes.
Optimized SMT Coplanarity: Precision-engineered with a strict strict flatness tolerance (0.15mm) to ensure exceptional soldering yields and minimize defects in automated SMT lines.
Flexible Ordering Configuration: Available from 3 to 40 pins per row, with comprehensive plating (Gold Flash, Gold 3U", Matte Tin) and packaging (Tray, Tube, Tape & Reel) customizable options.
Eco-Friendly Design: 100% RoHS & REACH compliant, with halogen-free materials optional to meet strict international environmental regulations.
