M20-7812045R

Overview

The M20-7812045R is a dual in-line (DIL) surface mount socket assembly manufactured by Harwin. It features a 2-row configuration with 40 positions and a standard 2.54 mm pitch. Designed for board-to-board applications, this component utilizes gold plating on its contacts to ensure reliable electrical connections. The receptacle supports both bottom and top entry orientations, providing flexibility during PCB layout and assembly processes.

Feature Summary

• Dual row DIL surface mount construction
• Gold contact plating for enhanced conductivity
• Flexible bottom or top entry orientation

Applications

• Board-to-board interconnects
• High-density PCB assemblies
• Industrial electronic modules

Procurement Notes

Verify the specific suffix 'R' against the official datasheet to confirm reel packaging requirements. Ensure compatibility with automated pick-and-place equipment specifications. Confirm that the gold plating specification meets the environmental conditions of the target application.

Selection Notes

Select this component when a high-contact-count surface mount solution is required. The dual-row design maximizes connection density within limited board space. Verify that the 2.54 mm pitch aligns with mating header dimensions and that the SMT process capabilities support the selected entry orientation.

Part Context

This part belongs to the M20 series, which provides industrial-standard connectors designed for robust performance. The series offers various configurations including single and double rows with different termination styles. This specific model represents a high-pin-count variant optimized for surface mounting technologies.
