M55-7021642R

Headers, Male Pins Overview

The M55-7021642R is a vertical male header connector from the Harwin Archer Kontrol series, designed for board-to-board applications. It features a 1.27mm (0.050 inch) pitch with 16 positions arranged in two rows. The connector utilizes phosphor bronze contacts with gold plating on the mating interface and tin plating on the tail, 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 mechanical specifications include an insulation height of 9.86mm and a stacking height of 11.1mm, 13.9mm, or 18.5mm depending on configuration. It employs a pin lock fastening system and supports surface mount soldering.

Headers, Male Pins Procurement Notes

Verify the specific suffix code against the official Harwin datasheet to confirm exact stacking height and packaging configuration. Ensure compatibility with automated assembly processes by confirming reel or cut-tape availability matches production requirements. Cross-reference the component specification document C04711 for detailed dimensional tolerances and mating partner definitions before finalizing procurement orders.

Headers, Male Pins Selection Notes

Select this component when a low-profile, high-reliability interconnect is required for dense board-to-board connections. The 1.27mm pitch allows for compact circuit layouts while maintaining adequate spacing. Consider the available stacking heights to ensure proper clearance within the enclosure. Verify that the mating receptacle belongs to the same M55-60xxx42R family to guarantee correct alignment and electrical continuity.

Headers, Male Pins Part Context

This part belongs to the M55-702xx42R family of vertical male headers within the Archer Kontrol line. It is specifically engineered as a counterpart to female receptacles like the M55-6021642R. The series is characterized by its robust construction and suitability for harsh environments, offering superior performance compared to standard connectors through its specialized locking and shielding features.

Headers, Male Pins Replacement Considerations

Direct substitutes within the same series include other position variants such as M55-7020842R or M55-7022442R, provided the pitch and mounting style remain identical. No cross-family replacements are recommended without verifying mechanical footprint and electrical rating compatibility.
