Overview

The M20-9980245 is a dual-row, 4-pin (2+2) vertical male header from Harwin's M20 series, featuring a standard 2.54mm (0.1 inch) pitch. This connector is designed for through-hole mounting and utilizes high-temperature plastic, making it compatible with modern lead-free reflow soldering processes. The pins are finished with gold plating on the contact area to ensure high reliability and oxidation resistance in demanding environments.

Why Choose This Part

The use of gold plating provides superior electrical conductivity and durability over multiple mating cycles compared to tin. Its high-temperature thermoplastic construction allows it to withstand high heat durante automated soldering without deformation. The 2.54mm pitch ensures compatibility with a vast ecosystem of standard connectors and prototyping accessories.

Applications
