M22-2721046

Headers, Male Pins Overview

The Harwin M22-2721046 is a dual in-line pin header from the M22 series, designed for board-to-board connections. It features a 2 mm pitch and a 2x10 contact configuration (20 positions total). The connector utilizes through-hole solder termination with right-angle mounting for vertical orientation. Contacts are made of phosphor bronze with tin plating, ensuring reliable conductivity. The housing is constructed from black nylon, providing electrical insulation. It operates within a temperature range of -40°C to +105°C and supports a current rating of 1 A per contact.

Headers, Male Pins Feature Summary

• Dual row male pin header design for high-density interconnects
• Right-angle vertical mounting configuration for space-efficient PCB layouts
• Tin-plated phosphor bronze contacts for corrosion resistance and signal integrity
• Nylon housing with UL 94 V-0 flammability rating for thermal stability

Headers, Male Pins Applications

• Industrial control systems requiring robust board-to-board linking
• Communication equipment internal module interconnections
• Automotive electronics harnesses and control units
• Test and measurement instrumentation circuit boards

Headers, Male Pins Procurement Notes

Verify the specific ordering suffix against the official Harwin datasheet to confirm exact contact count, plating type, and orientation. Ensure compatibility with mating socket housings or female headers within the same M22 series family. Check RoHS compliance status and lead times directly with authorized distributors, as availability may vary by region and production batch.

Headers, Male Pins Selection Notes

Select this component when a 2 mm pitch dual-row header is required for vertical PCB assembly. Confirm that the 1 A current rating and 650 VAC voltage limit meet the application's electrical requirements. Ensure the PCB footprint matches the 2 mm x 2 mm grid pattern. Consider tin plating for general use; upgrade to gold if low-contact-resistance environments are critical.

Headers, Male Pins Part Context

The M22 series is a comprehensive system of connectors offering various pitches and configurations. The M22-2721046 specifically addresses the need for compact, high-pin-count vertical interconnects. It complements other M22 variants like the M22-2040446, differing primarily in row count, position quantity, and mounting angle. This part fits into Harwin's strategy of providing modular connectivity solutions for diverse electronic industries.

Headers, Male Pins Replacement Considerations

Direct substitutes must match the 2 mm pitch, 2x10 configuration, and right-angle through-hole format. Verify mechanical dimensions and contact material compatibility before swapping. Generic equivalents may lack the precise locking mechanisms or flammability ratings of the original Harwin component.
