M55-7028042R

Headers, Male Pins Overview

The Harwin M55-7028042R is an Archer Kontrol series board-to-board and mezzanine connector designed for high-density interconnect applications. It features a male pin configuration with 80 positions arranged in a dual-row layout. The component utilizes a precise 1.27 mm pitch to ensure reliable signal transmission. Electrical ratings include a current capacity of 1.2 A and a voltage rating of 100 VAC. The contacts are constructed from phosphor bronze with gold plating, housed within a liquid crystal polymer (LCP) body rated UL 94 V-0. It supports surface mount technology with a vertical orientation and operates within a temperature range of -55°C to +125°C.

Headers, Male Pins Procurement Notes

Verify the specific datasheet revision when sourcing this component to ensure compatibility with latest manufacturing standards. Confirm that the gold plating thickness meets your application's wear requirements. Ensure storage conditions prevent moisture absorption in the LCP housing prior to soldering. Validate that the supplier provides traceable documentation for RoHS compliance. Cross-reference the reel packaging specifications if using automated placement equipment.

Headers, Male Pins Selection Notes

Select this part when a vertical male header is required for mating with female sockets in confined spaces. The 1.27 mm pitch allows for significant pin counts without excessive board area consumption. Consider the 1.2 A current rating for power distribution needs alongside signal lines. The UL 94 V-0 flammability rating makes it suitable for safety-critical enclosures. Evaluate the operating temperature range against your environmental constraints.

Headers, Male Pins Part Context

This component belongs to the Harwin Archer Kontrol family, which specializes in robust, high-reliability connectors for demanding environments. The M55 series is engineered for applications requiring repeated mating cycles or harsh vibration resistance. As a male header, it serves as the stationary counterpart to female socket connectors in system assemblies.

Headers, Male Pins Replacement Considerations

Direct substitutes within the same pitch and row count should be verified for mechanical footprint compatibility. Check mating dimensions carefully when considering alternative manufacturers. Ensure equivalent electrical ratings and material compositions to maintain system integrity.
