M55-7102042R

Headers, Male Pins Overview

The Harwin M55-7102042R is a board-to-board and mezzanine connector from the Archer Kontrol series. It features a male header configuration with 20 positions arranged in two rows. The connector utilizes a 1.27 mm pitch and employs surface mount technology (SMT) for termination. It is designed with a right-angle orientation for vertical mounting on the PCB. The unit supports a current rating of 1.2 A and a voltage rating of 100 VAC. Operating temperatures range from -55°C to +125°C. Contact plating consists of gold over phosphor bronze, housed in liquid crystal polymer (LCP).

Headers, Male Pins Feature Summary

• Archer Kontrol series design ensures precise alignment and secure mating.
• Right-angle surface mount construction facilitates compact vertical stacking.
• Gold-plated phosphor bronze contacts provide reliable signal transmission.
• Liquid crystal polymer housing offers high thermal stability and UL 94 V-0 flammability rating.

Headers, Male Pins Applications

• High-density electronic assemblies requiring vertical interconnects.
• Mezzanine card connections in modular systems.
• Board-to-board interfaces in telecommunications equipment.
• Compact consumer electronics with strict height constraints.

Headers, Male Pins Procurement Notes

Verify the specific part number against official Harwin documentation to confirm the right-angle SMT header configuration. Ensure compatibility with the corresponding female counterpart within the Archer Kontrol family. Check RoHS compliance status via the manufacturer's datasheet. Confirm that the 20-position count and 1.27 mm pitch match the target PCB footprint requirements before procurement.

Headers, Male Pins Selection Notes

Select this component when a right-angle male header is required for vertical board stacking. The 1.27 mm pitch suits applications needing moderate pin density without excessive board space consumption. Verify that the 1.2 A current rating meets the circuit load requirements. Consider the total mating length specifications if integrating with other stack heights in the same assembly.

Headers, Male Pins Part Context

This component belongs to the Harwin M55 Archer Kontrol family, which specializes in high-reliability interconnect solutions. The series is engineered for demanding environments, offering robust mechanical performance alongside electrical stability. The M55-7102042R specifically addresses needs for right-angle connectivity, distinguishing it from straight or horizontal variants within the broader product line.

Headers, Male Pins Replacement Considerations

Direct substitutes include other Harwin Archer Kontrol male headers with identical 20-position counts and 1.27 mm pitch. Compatible alternatives must match the right-angle SMT form factor and LCP housing material. Cross-model replacements require verification of mating dimensions and contact plating specifications to ensure functional equivalence.
