M55-7023242R

Headers, Male Pins Overview

The M55-7023242R is a 32-position, dual-row board-to-board header from the Harwin Archer Kontrol series. It features a 1.27 mm (0.050 inch) mating pitch and vertical surface-mount installation. The connector utilizes phosphor bronze contacts with gold plating on the mating interface and tin plating on the tail. Rated for 1.2 A at 100 VAC, it operates within a temperature range of -55°C to +125°C. The housing is constructed from black liquid crystal polymer (LCP) with UL94 V-0 flammability rating. Mating stacking heights are available in 11.1 mm, 13.9 mm, or 18.5 mm configurations.

Headers, Male Pins Feature Summary

• Robust four-wall shielding design ensures secure alignment and mechanical stability during board-to-board connections.
• Integrated pin lock mechanism provides positive retention between mated headers and sockets.
• Compatible with automated pick-and-place assembly processes due to tape-and-reel packaging.

Headers, Male Pins Applications

• Industrial control systems requiring high-reliability interconnects
• Automotive electronic modules
• General-purpose circuit board assemblies

Headers, Male Pins Procurement Notes

Verify that the specific stacking height requirement matches the intended mating socket configuration, as the M55-7023242R supports multiple stack heights. Confirm that the surface-mount footprint aligns with the PCB layout guidelines provided in the official datasheet. Ensure compatibility with the corresponding female socket part number within the same Archer Kontrol series to maintain electrical and mechanical integrity.

Headers, Male Pins Selection Notes

Select this component when a dual-row, 1.27 mm pitch header is required for vertical board-to-board applications. The choice depends on the need for a 32-position count and specific stacking height constraints. Consider the thermal operating range and current rating against the system's electrical demands. Verify that the surface-mount technology fits the manufacturing capabilities and that the locking feature meets the mechanical security requirements of the assembly.

Headers, Male Pins Part Context

This part belongs to the Harwin M55-702 series, specifically the Archer Kontrol line designed for robust industrial environments. It is a male header variant within the broader M55 family, which includes various pin counts and stacking heights. The series is characterized by its high reliability and precise alignment features, distinguishing it from standard commercial connectors through enhanced mechanical retention and shielding.

Headers, Male Pins Replacement Considerations

Direct substitutes include other M55-702xxxxxR variants with identical 32-position, 1.27 mm pitch specifications but potentially different stacking heights or contact lengths. Cross-series replacements require verification of mating interface dimensions and electrical ratings to ensure functional equivalence without redesigning the PCB footprint.
