M20-7883642

Overview

The M20-7883642 is a rectangular connector receptacle from the Harwin M20 series, designed for board-to-board or cable stacking applications. It features 72 positions with a 0.100 inch (2.54mm) pitch in a dual-row configuration. The component utilizes gold-plated contacts and is available in a right-angle PCB mount style. Key electrical ratings include a current capacity of 3A and a voltage rating of 1000V. The operating temperature range spans from -40°C to +105°C. The housing is constructed from black UL94 V-0 rated insulating material, ensuring flame resistance and thermal stability for industrial environments.

Feature Summary

• Right-angle PCB mounting design facilitates compact vertical space utilization in dense electronic assemblies.
• Gold-plated contact surfaces provide reliable signal transmission and corrosion resistance over extended service life.
• Dual-beam contact structure enhances mechanical retention and electrical connection stability during mating cycles.

Applications

• Embedded PC motherboard interconnections
• Industrial monitoring system backplanes
• Telecommunications equipment signal routing

Procurement Notes

Verify the specific suffix code against official Harwin documentation to confirm the right-angle orientation and plating specifications. Ensure compatibility with mating header assemblies regarding stack height and pin count. Confirm RoHS compliance status through the latest manufacturer datasheet before integration into regulated product lines.

Selection Notes

Select this component when high-density 72-position connectivity is required in a constrained vertical profile. The right-angle form factor suits applications where board edge access is limited. Validate that the 1000V rating meets circuit isolation requirements and that the 3A current capacity aligns with load demands.
