M55-7012642R

Headers, Male Pins Overview

The M55-7012642R is a surface-mount board-to-board header from the Harwin Kontrol series. It features 26 positions arranged in a dual-row configuration with a 1.27mm pitch. The connector utilizes phosphor bronze contacts with gold plating on the mating interface and tin on the posts, housed in black liquid crystal polymer (LCP). Rated for 1.2A at 100VAC, it operates within a temperature range of -55°C to 125°C. Key specifications include an insulation height of 8.25mm, UL94 V-0 flammability rating, and compatible stacking heights of 9.5mm, 12.3mm, and 16.9mm.

Headers, Male Pins Procurement Notes

Verify that the specific order suffix matches the required contact finish and packaging format. Confirm that the receiving facility has the necessary equipment for surface-mount assembly processes. Ensure that the specified stacking height requirements align with the target application's mechanical constraints before finalizing procurement orders.

Headers, Male Pins Selection Notes

Select this component when high-density vertical interconnects are required for space-constrained designs. The shrouded architecture provides superior protection against misalignment compared to open-frame alternatives. Consider the specific stacking height options available to accommodate varying board thicknesses and enclosure depths effectively.
