M20-7821942

Overview

The Harwin M20-7821942 is a 19-position dual-in-line (DIL) socket assembly from the M20 series. It features a 2.54 mm pitch and is designed for vertical through-hole mounting on printed circuit boards. The connector utilizes gold and tin plating on its contacts to ensure reliable signal transmission. Rated for industrial applications, it supports general-purpose and telecommunications environments with robust insulation materials.

Feature Summary

• Vertical through-hole installation for secure PCB attachment
• Gold and tin contact plating for enhanced conductivity
• Dual-in-line configuration for high-density interconnects

Applications

• Industrial control systems
• Telecommunications equipment
• General-purpose electronic assemblies

Procurement Notes

Verify the specific pin count and plating configuration against the official datasheet before integration. Confirm that the vertical orientation and through-hole termination method align with the target PCB layout requirements. Ensure compatibility with mating header components within the same M20 series family to maintain mechanical and electrical integrity.

Selection Notes

Select this component when a 19-pin vertical socket is required for board-to-board connections. The M20 series offers a compact form factor suitable for space-constrained designs. Consider the gold-tin plating option if superior corrosion resistance and low contact resistance are critical for the application environment.
