This document describes the features and characteristics of the A142 1.27mm Pitch Multi-function Two Piece Connector FX2 Series.
The FX2 series offers a variety of connection types—including vertical, horizontal, board‑to‑board, board‑to‑cable and SMT—each designed for easy one‑touch operation and reliable locking. Features such as mis‑insertion prevention, flux‑tight designs, and optional metal tabs for solder strength are described.
The handbook includes detailed specifications (current rating, voltage rating, temperature and humidity ranges, insulation resistance, vibration tolerance, and durability), ordering tables for different contact counts, functional flow charts, and recommended soldering profiles for both reflow and manual processes.
