3-1971906-2 – TE CONNECTIVITY

Overview

The TE Connectivity 3-1971906-2 is a robust, shrouded header designed for reliable interconnectivity in demanding environments. Its primary function is to provide a secure, polarized mating interface for wire-to-board applications, ensuring correct assembly and preventing misconnections. A critical design consideration for this 0.130″ pitch connector is managing thermal expansion and contraction within the polyamide insulation material, especially when subjected to the specified -30°C to 105°C operating temperature range, which can impact contact pressure and signal integrity over time if not properly accounted for in the PCB layout and enclosure design.
