M55-7018042R

Headers, Male Pins Overview

The M55-7018042R is a vertical male board-to-board connector from the Harwin Archer Kontrol M55 series. It features an 80-position layout with a 1.27 mm pitch across two rows. Designed for surface mount technology, it utilizes solder termination and includes mounting pegs for secure PCB attachment. The connector supports a maximum current of 1.2 A and withstands voltages up to 100 VAC. Operating temperatures range from -55°C to +125°C. Gold-plated phosphor bronze contacts ensure reliable performance within Liquid Crystal Polymer (LCP) housings rated UL 94 V-0.

Headers, Male Pins Procurement Notes

Verify the specific part number against official Harwin documentation to confirm pin count and pitch specifications. Ensure compatibility with surface mount reflow profiles and verify that the required mounting pegs are included for mechanical stability during assembly. Cross-reference RoHS compliance status with the latest manufacturer declarations.

Headers, Male Pins Selection Notes

Select this component when a vertical, high-density connection is required for surface mount applications. The 1.27 mm pitch allows for compact designs while maintaining signal integrity. Consider the 1.2 A current rating and 100 VAC voltage limit to ensure electrical safety margins are met for the target circuit design requirements.

Headers, Male Pins Part Context

This connector belongs to the Archer Kontrol M55 series, which focuses on high-reliability board-to-board connections. The series is characterized by its robust mechanical design and suitability for automated pick-and-place manufacturing. The M55-7018042R specifically addresses needs for dense interconnects in space-constrained environments requiring stable vertical mating.

Headers, Male Pins Replacement Considerations

Direct substitutes must match the 1.27 mm pitch, 80-position count, vertical orientation, and surface mount termination style. Verify that alternative components offer compatible current ratings and housing materials to ensure mechanical and electrical equivalence in the final assembly.
