M22-2021005

Headers, Male Pins Overview

The Harwin M22-2021005 is a vertical pin strip header from the M22 series, designed for through-hole PCB mounting. It features a 2mm pitch with 20 positions arranged in a dual-row configuration. The connector utilizes square male pins made of phosphor bronze with gold plating on the mating interface. Constructed with black PA6T insulation rated UL94 V-0, it supports a maximum current of 1A per contact and operates within a temperature range of -40°C to +105°C.

Headers, Male Pins Feature Summary

• Dual-row pin strip design optimized for board-to-board interconnections
• Push-pull locking mechanism ensures secure mating engagement
• Gold-plated phosphor bronze contacts provide reliable electrical performance
• Cuttable construction allows for flexible circuit board layout adaptation

Headers, Male Pins Applications

• Board-to-board interconnection systems
• High-density PCB assembly applications
• Industrial electronic equipment interfaces
• Consumer device internal connectivity

Headers, Male Pins Procurement Notes

Verify the specific part number against official Harwin documentation to confirm the dual-row configuration and 20-position count. Ensure compatibility with mating socket components such as the M22-6361042 or M22-6341042 series. Confirm that the through-hole mounting style aligns with the target PCB fabrication capabilities and thermal processing requirements.

Headers, Male Pins Selection Notes

Select this component when a robust, cuttable dual-row header is required for space-constrained designs. The 2mm pitch offers a balance between density and handling ease. Consider the push-pull retention feature if vibration resistance is critical. Verify that the 1A current rating per contact meets the system's power distribution needs without requiring derating due to ambient temperature conditions.

Headers, Male Pins Part Context

This component belongs to the Harwin M22 series, which provides industrial-standard connectors for high-reliability applications. The series is characterized by its compact form factor and durable materials, suitable for environments demanding consistent performance. The M22-2021005 specifically addresses the need for versatile, multi-position connections in modern electronics manufacturing.

Headers, Male Pins Replacement Considerations

Direct substitutes within the same series include variations in position count or row configuration, such as M22-2021405 for different pin counts. Cross-series replacements require matching the 2mm pitch, through-hole termination, and dual-row geometry to ensure mechanical and electrical compatibility.
