M55-7012042R

Headers, Male Pins Overview

The Harwin M55-7012042R is a 20-position, two-row vertical male board-to-board and mezzanine connector from the Archer Kontrol series. It features a 1.27 mm pitch with gold-plated phosphor bronze contacts housed in liquid crystal polymer (LCP). The component supports surface mount termination with a stacking height of 8.25 mm and a contact length of 4.00 mm. Rated for 1.2 A current and 100 VAC voltage, it operates between -55°C and +125°C. The shrouded four-wall design ensures alignment, while UL 94 V-0 flammability rating and 10 GOhms insulation resistance define its electrical safety standards.

Headers, Male Pins Procurement Notes

Verify that the ordering suffix matches the required reel or cut tape packaging format. Confirm the specific pin count and row configuration aligns with the target PCB footprint. Ensure the voltage and current ratings meet the system requirements. Check for RoHS compliance documentation if environmental regulations apply. Validate the mounting peg style against the assembly process capabilities.

Headers, Male Pins Selection Notes

Select this component when a 1.27 mm pitch male header with mechanical latching is required. The shrouded design is suitable for applications needing guided insertion to prevent misalignment. Consider the 8.25 mm stacking height for space-constrained vertical assemblies. The LCP housing and gold contacts support environments requiring high thermal stability and corrosion resistance.

Headers, Male Pins Part Context

This part belongs to the Harwin M55 Archer Kontrol family, designed for robust electronic interconnects. The series emphasizes mechanical security through its unique locking feature, distinguishing it from standard headers. It serves as a male counterpart to compatible female connectors within the same architectural ecosystem, ensuring consistent performance across multi-layer board systems.

Headers, Male Pins Replacement Considerations

Compatible substitutes include other Harwin M55 series variants with matching 1.27 mm pitch and 20-position counts. Verify that alternative parts maintain the same shrouded four-wall geometry and latch lock functionality. Ensure the replacement offers identical stacking height and contact material specifications to preserve mechanical and electrical integrity.
