G125-MS11205L3R

Overview

The Harwin G125-MS11205L3R is a Gecko-Latch series pin header designed for surface mount technology. It features a 1.25 mm pitch with 12 positions arranged in two rows. The connector utilizes male pins with gold plating on phosphor bronze contacts, rated for 2 A current and 450 VAC/DC voltage. The housing is constructed from black polyamide (PA4T) with UL94 V-0 flammability rating. It includes a four-wall shroud and board lock features for secure assembly.

Feature Summary

• Integrated latch lock mechanism ensures secure mating retention
• Four-wall shrouded design provides alignment and protection
• Board lock feature prevents movement during soldering
• Gold-plated phosphor bronze contacts ensure reliable conductivity

Applications

• Surface mount interconnections in compact electronic assemblies
• Power distribution boards requiring secure locking headers
• Industrial control systems needing vibration-resistant connections
• Consumer electronics utilizing wire-to-board interfaces

Procurement Notes

Verify the specific suffix 'L3R' corresponds to the tape and reel packaging configuration as indicated by distributor data. Confirm that the black housing variant matches the required aesthetic or identification standards for the target application. Ensure compatibility with automated pick-and-place equipment due to the surface mount footprint and reel format specifications.

Selection Notes

Select this component when a locked, surface-mount header with a 1.25 mm pitch is required. The Gecko-Latch system offers superior retention compared to standard headers. Consider the 2 A current rating and 450 V insulation capability for appropriate electrical isolation. The straight mounting angle suits vertical board-to-board or wire-to-board applications where space efficiency is critical.

Part Context

This part belongs to Harwin's Gecko-Latch family, which emphasizes high-reliability connections through mechanical latching. The G125 series specifically targets applications demanding robust retention forces in small form factors. The MS designation indicates a male pin header variant suitable for mating with female sockets or cables.

Replacement Considerations

No direct public substitute part numbers are confirmed for this specific configuration. Alternative connectors must match the 1.25 mm pitch, 2x6 layout, SMT mounting style, and locking mechanism requirements to ensure functional interchangeability.
