M20-7810645

Overview

The Harwin M20-7810645 is a surface mount socket assembly from the M20 series, designed for board-to-board and wire-to-board connections. It features a dual in-line configuration with 12 positions arranged in two rows of six. The connector utilizes a 2.54 mm (0.1 inch) pitch and accepts bottom or top entry mating options. Contacts are gold-plated over tin to ensure reliable signal transmission. This component is intended for high-density electronic applications requiring robust surface mounting capabilities.

Feature Summary

• Dual in-line socket assembly design supporting both bottom and top entry configurations
• Gold-plated contacts over tin finish for enhanced conductivity and corrosion resistance
• Surface mount termination method suitable for automated PCB assembly processes

Applications

• High-density board-to-board interconnections
• Wire-to-board connection systems
• Compact electronic device internal wiring

Procurement Notes

Verify the specific ordering suffix against the official Harwin datasheet to confirm contact plating and entry orientation. Ensure the selected variant matches the required surface mount footprint and row configuration. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm current availability status and compliance documentation prior to procurement.

Selection Notes

Select this component when a 12-position dual-row socket is required for surface mounting. The 2.54 mm pitch ensures compatibility with standard header pins. Consider the gold-over-tin plating for environments where oxidation resistance is critical. Verify that the PCB layout accommodates the specific surface mount pad dimensions defined in the mechanical drawings.
