M20-7880542

Overview

The M20-7880542 is a horizontal pin header from the Harwin M20 series, designed for board-to-board interconnections. It features a 10-position configuration (5+5) with a 2.54 mm pitch across two rows. The connector utilizes tin-plated contacts and is rated for 3A current at voltages up to 1kV. Constructed with a black polyamide housing meeting UL94 V-0 flammability standards, it operates within a temperature range of -40°C to 105°C.

Feature Summary

• Horizontal orientation facilitates compact PCB stacking and low-profile assembly requirements.
• High voltage rating of 1kV ensures reliable insulation performance in demanding electrical environments.
• Tin-plated contact finish provides effective corrosion resistance and solderability for secure connections.

Applications

• Board-to-board interconnects requiring high voltage isolation
• Compact electronic modules with strict height constraints
• Industrial control systems operating in extreme temperatures

Procurement Notes

Verify the specific part number suffix against official Harwin documentation to confirm the exact plating type and housing color variant. Ensure compatibility with mating receptacles regarding vertical stack height and alignment tolerances. Confirm RoHS compliance status through the manufacturer's latest environmental declaration before final procurement integration.

Selection Notes

Select this component when horizontal mounting is required to minimize profile height while maintaining robust electrical connectivity. The 1kV rating makes it suitable for applications exceeding standard low-voltage limits. Consider the tin plating for cost-effective solutions where gold plating is unnecessary, ensuring adequate durability for the intended mating cycles.
