M55-7026842R

Headers, Male Pins Overview

The Harwin M55-7026842R is a board-to-board and mezzanine connector from the Archer Kontrol M55 series. It features a 1.27 mm pitch, 2-row configuration with 68 positions. The component is a male surface-mount connector designed for vertical installation. Key electrical ratings include a current capacity of 1.2 A and a voltage rating of 100 VAC. The operating temperature range spans from -55°C to +125°C. Contacts are gold-plated phosphor bronze housed in UL 94 V-0 rated Liquid Crystal Polymer (LCP).

Headers, Male Pins Feature Summary

• Archer Kontrol mechanical alignment system ensures precise mating.
• Vertical surface-mount design facilitates compact stack-up integration.
• Gold-plated contacts provide reliable signal transmission.

Headers, Male Pins Applications

• High-density electronic assemblies requiring precise alignment.
• Mezzanine card interconnections.
• Board-to-board data and power distribution.

Headers, Male Pins Procurement Notes

Verify the specific suffix against official Harwin documentation to confirm pin count and orientation. Ensure compatibility with the corresponding female housing within the same M55 series. Confirm RoHS compliance status through the manufacturer's latest certification documents before finalizing procurement specifications.

Headers, Male Pins Selection Notes

Select this component when a 68-position vertical male header is required. The 1.27 mm pitch suits applications needing high density without excessive height. Verify that the mating female connector supports the 1.2 A current rating and 100 VAC insulation requirements. Ensure PCB layout accommodates the vertical profile and mounting pegs.

Headers, Male Pins Part Context

This part belongs to the Harwin M55 series, known for its robust mechanical locking mechanism. The Archer Kontrol feature provides positive engagement and prevents accidental disconnection. It is distinct from standard headers by offering enhanced stability in high-vibration environments.

Headers, Male Pins Replacement Considerations

Direct substitutes must match the 1.27 mm pitch, 68 positions, and vertical male configuration. Verify that alternative components support the same UL 94 V-0 flammability rating and LCP material properties. Cross-reference mating connectors to ensure interface compatibility.
