M22-2021746

Headers, Male Pins Overview

The M22-2021746 is a vertical pin header connector from the Harwin M22 series, designed for board-to-board or cable applications. It features a 34-position configuration with a 2mm pitch and dual in-line layout (17+17). The connector utilizes phosphor bronze male pins with gold plating, housed in black polyamide insulation rated UL94 V-0. Rated at 1A per contact, it supports through-hole termination and operates within a temperature range of -40°C to 105°C.

Headers, Male Pins Feature Summary

• Cuttable design allows for flexible positioning and custom length adaptation on PCBs.
• Push-pull locking mechanism ensures secure mating with compatible socket connectors.
• Gold-plated phosphor bronze contacts provide reliable conductivity and corrosion resistance.

Headers, Male Pins Applications

• High-density electronic assemblies requiring precise board-to-board interconnection
• Industrial control systems utilizing modular connector architectures
• Automotive electronics modules demanding robust mechanical retention

Headers, Male Pins Procurement Notes

Verify that the specific order matches the M22-2021746 part number exactly, as the M22 series contains numerous variants with differing pin counts and orientations. Confirm compatibility with mating sockets such as the M22-636 series. Ensure procurement sources provide original manufacturer documentation to validate material specifications and UL certification status.

Headers, Male Pins Selection Notes

Select this component when a 34-position vertical header with 2mm pitch is required for high-reliability connections. Consider the cuttable feature if standard lengths do not fit the design. Verify that the 1A current rating per contact meets the circuit requirements. Ensure the through-hole mounting style aligns with the PCB fabrication capabilities and assembly processes.

Headers, Male Pins Part Context

This component belongs to the Harwin M22 series, which defines a family of 2mm pitch connectors known for their push-pull locking system. The series includes headers, sockets, and wire housings available in various row configurations and termination styles. The M22-2021746 specifically represents the vertical pin header variant within this standardized ecosystem.

Headers, Male Pins Replacement Considerations

Compatible substitutes include other M22 series headers with identical 2mm pitch and push-pull locking mechanisms, provided the pin count and orientation match. Direct replacements must maintain the same electrical ratings and mechanical footprint to ensure interchangeability without redesigning the PCB layout.
