Overview

The TE Connectivity Dynamic 1000 Series PCB Mount Header (SKU: 1-1939638-3) delivers precision wire-to-board interconnect solutions for high-density electronic assemblies. This 26-position, fully shrouded header features a compact 2mm [0.079 in] centerline pitch and horizontal PCB mounting configuration, optimizing space in compact designs. Gold-plated contacts provide superior signal integrity and corrosion resistance, ensuring reliable performance in demanding industrial, telecommunications, and computing environments. The through-hole solder termination guarantees secure mechanical and electrical connections, while the fully shrouded design offers enhanced mechanical protection and precise pin alignment during assembly. Engineered for high-reliability applications, this connector supports dynamic signal transmission with consistent impedance control. Its 2mm pitch is compatible with standard PCB layouts, reducing design complexity for engineers working with microcontrollers, FPGAs, or high-speed data interfaces. The Dynamic 1000 Series is part of TE Connectivity’s robust interconnect portfolio, trusted in mission-critical systems where signal integrity and durability are non-negotiable. Key specifications include: 26 positions, 2mm centerline, gold plating (contact area), through-hole solder termination, and horizontal PCB mount. The fully shrouded housing prevents misalignment during mating and protects against mechanical stress, making it ideal for automated assembly lines. Whether deployed in industrial automation, telecom infrastructure, or advanced computing platforms, this header ensures stable, long-term connectivity with minimal signal degradation.
