M50-3502542

Headers, Male Pins Overview

The Harwin M50-3502542 is a 50-position, double-row pin header from the Archer M50 series. It features a 1.27 mm pitch and is designed for vertical through-hole mounting on printed circuit boards. The connector utilizes gold-plated copper alloy contacts to ensure reliable signal transmission. Rated for 1A current, it operates within a temperature range of -40°C to +105°C. The unshrouded design facilitates board-to-board or wire-to-board interconnections.

Headers, Male Pins Feature Summary

• Vertical through-hole mounting configuration for secure PCB attachment
• Gold-plated contacts provide corrosion resistance and stable electrical performance
• Unshrouded double-row layout allows for flexible mating options

Headers, Male Pins Applications

• Board-to-board interconnects in compact electronic assemblies
• Wire-to-board connections requiring high-density routing
• Industrial control systems operating in extreme temperatures

Headers, Male Pins Procurement Notes

Verify the specific part number M50-3502542 against project requirements to ensure compatibility with mating connectors. Confirm that the through-hole footprint matches the PCB design. Check environmental compliance documentation such as RoHS status if required for the target market. Ensure storage conditions maintain contact integrity prior to assembly.

Headers, Male Pins Selection Notes

Select this component when a 1.27 mm pitch male header is required for vertical installation. The unshrouded design is suitable where space constraints allow direct access to pins. Consider the 1A current rating and thermal limits for the intended application load. Verify that the copper alloy contact material meets the conductivity needs of the system.

Headers, Male Pins Part Context

This component belongs to the Harwin Archer M50 series, which offers various configurations including shrouded and surface-mount options. The M50-3502542 specifically represents the straight, through-hole, unshrouded variant with 50 positions. This series is engineered for high-reliability applications in demanding environments.

Headers, Male Pins Replacement Considerations

Direct substitutes must match the 1.27 mm pitch, 2x25 position count, and through-hole termination style. Verify that alternative headers share the same gold plating thickness and current ratings. Ensure mechanical dimensions align with existing PCB layouts to avoid fitment issues during assembly.
