M55-6022042R

Headers, Receptacles, Female Sockets Overview

The Harwin M55-6022042R is a board-to-board and mezzanine connector from the Archer Kontrol series. It features a 20-position female receptacle with a 1.27 mm pitch and two rows. Designed for vertical surface mount technology, it utilizes solder termination. The connector has a current rating of 1.2 A and a voltage rating of 100 VAC. Operating temperatures range from -55°C to +125°C. Contacts are made of phosphor bronze with gold plating, housed in liquid crystal polymer rated UL 94 V-0.

Headers, Receptacles, Female Sockets Feature Summary

• Vertical surface mount design for direct PCB integration
• Gold-plated phosphor bronze contacts for reliable signal transmission
• UL 94 V-0 rated liquid crystal polymer housing for flame resistance
• Archer Kontrol series robustness with mounting peg support

Headers, Receptacles, Female Sockets Applications

• Board-to-board interconnections
• Mezzanine connectivity
• Industrial electronics assemblies
• Automotive control modules

Headers, Receptacles, Female Sockets Procurement Notes

Verify the specific part number M55-6022042R against official Harwin documentation to confirm the 20-position configuration and vertical SMT orientation. Ensure compatibility with mating male headers within the same Archer Kontrol series. Check RoHS compliance status via the manufacturer's latest datasheet before procurement.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when a low-profile, high-density vertical connection is required. The 1.27 mm pitch suits applications needing moderate pin counts in limited space. Verify that the mating connector supports the specified 1.2 A current rating and 100 VAC insulation requirements. Confirm mechanical stack-up height constraints align with the connector profile.

Headers, Receptacles, Female Sockets Part Context

This part belongs to the Harwin M55 Archer Kontrol family, known for robust board-to-board solutions. It complements male counterparts like the M55-70xxx42R series. The vertical orientation distinguishes it from right-angle variants such as the M55-61xxx42R series. It serves as a standard interconnect solution in compact electronic systems requiring reliable surface mount assembly.

Headers, Receptacles, Female Sockets Replacement Considerations

Direct substitutes include other Harwin M55 series connectors with matching 20 positions, 1.27 mm pitch, and vertical SMT form factor. Cross-referencing with M55-6012642R or M55-6006842R requires verifying position count differences. No non-Harwin equivalents are confirmed in public data.
