M55-6011642R

Headers, Receptacles, Female Sockets Overview

The M55-6011642R is a vertical surface-mount board-to-board connector from Harwin's Archer Kontrol series. It features a 1.27mm (0.050 inch) pitch with 16 positions arranged in two rows. The housing is constructed from black Liquid Crystal Polymer (LCP) rated UL94 V-0, providing high thermal stability. Contacts are made of phosphor bronze with a gold plating on the mating interface and tin plating on the tail for soldering. The connector supports a maximum current of 1.2A and operates within a temperature range of -55°C to +125°C.

Headers, Receptacles, Female Sockets Feature Summary

• Vertical surface-mount design optimized for automated pick-and-place assembly
• Gold-plated phosphor bronze contacts ensure reliable signal transmission
• UL94 V-0 rated LCP insulation offers robust thermal and chemical resistance
• Integrated mounting pegs provide mechanical stability during soldering

Headers, Receptacles, Female Sockets Applications

• Automotive control modules requiring stable switching characteristics
• Industrial electronic assemblies demanding high-density interconnects
• General-purpose board-to-board connections in compact devices

Headers, Receptacles, Female Sockets Procurement Notes

Verify that the specific suffix '42R' corresponds to the required reel packaging configuration as defined by the manufacturer. Confirm that the vertical orientation and 16-position count match the target PCB footprint requirements. Ensure compatibility with standard SMT reflow profiles for tin-plated tails. Cross-reference the UL94 V-0 rating against specific environmental regulations if applicable to the end-use application.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when a vertical, low-profile interconnect solution is required for space-constrained designs. The 1.27mm pitch allows for higher density compared to standard 2.54mm headers. The Archer Kontrol series provides enhanced mechanical retention through its pin-lock system. Consider the 1.2A current rating and 100VAC voltage limit when designing for power distribution or high-signal integrity applications.

Headers, Receptacles, Female Sockets Part Context

This part belongs to the Harwin M55 series, specifically the Archer Kontrol line designed for robust board-to-board and mezzanine applications. It complements male header counterparts such as the M55-7021642R to form complete interconnect systems. The series emphasizes reliability in automotive and industrial sectors through rigorous testing standards and material selection.

Headers, Receptacles, Female Sockets Replacement Considerations

Direct substitutes include other 16-position, 1.27mm pitch vertical female connectors from the same family, such as the M55-6011642R variants with different stacking heights. Verify that any alternative maintains the same contact material, plating thickness, and UL94 V-0 insulation rating to ensure equivalent performance.
