M55-7011242R

Headers, Male Pins Overview

The M55-7011242R is a 12-position, dual-row board-to-board and mezzanine connector from the Harwin Archer Kontrol series. It features a 1.27 mm (0.050 in) pitch with vertical male surface-mount termination. The connector utilizes phosphor bronze contacts with gold plating for mating surfaces and tin plating for soldering, housed in black liquid crystal polymer (LCP). It supports a rated current of 1.2 A and operates within a temperature range of -55°C to +125°C. The unit weighs 528 mg and includes mounting pegs for secure installation.

Headers, Male Pins Feature Summary

• Vertical male header design for direct board-to-board stacking applications
• Integrated four-wall shielding for enhanced electromagnetic interference protection
• Solder retention and pick-and-place compatibility for automated assembly processes
• High-density interconnect capability with precise 1.27 mm positioning

Headers, Male Pins Applications

• Automotive electronic control units
• Industrial instrumentation systems
• General-purpose high-density circuit boards

Headers, Male Pins Procurement Notes

Verify that the specific ordering suffix matches the required connector height variant, as the M55 series offers multiple height options such as 6.75mm, 8.25mm, or 9.85mm depending on the middle digit configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure that the selected packaging format aligns with available automated handling equipment specifications.

Headers, Male Pins Selection Notes

Select this component when a vertical orientation is required for compact stack-up designs. The dual-row configuration maximizes pin density within a limited footprint. Consider the 1.2 A current rating against total load requirements. Verify that the LCP housing material meets thermal stability needs for the intended operating environment and reflow soldering profiles.

Headers, Male Pins Part Context

This part belongs to the Harwin Archer Kontrol M55 family, designed for high-reliability interconnect solutions. The series emphasizes robust mechanical locking via pins and consistent electrical performance in demanding environments. It serves as a specialized solution for applications requiring shielded, high-density connections between adjacent printed circuit boards.

Headers, Male Pins Replacement Considerations

Direct substitutes include other Harwin M55 variants with identical 12-position counts and 1.27 mm pitch but different heights, such as M55-7001242R or M55-7021242R. Cross-brand replacements require careful verification of mating dimensions, shielding continuity, and contact geometry to ensure functional equivalence.
