Overview
The Harwin G125-MS11205M1R is a Gecko-Latch series header connector designed for surface mount technology. It features a 1.25mm pitch with 12 positions arranged in a 2x6 configuration. The component utilizes gold-plated phosphor bronze contacts and a black polyamide insulation body rated UL94 V-0. Electrical ratings include 2A current capacity and 450VAC/DC voltage tolerance. Operating temperatures range from -65°C to +150°C, ensuring reliability across diverse industrial environments.
Feature Summary
- Integrated pin lock mechanism provides secure board retention
- Four-wall shielding design enhances environmental protection
- Vertical surface mount termination facilitates automated assembly
Applications
- Industrial control system interconnections
- Power distribution modules
- Automotive electronic assemblies
Procurement Notes
Verify the specific suffix 'M1R' confirms tape and reel packaging requirements against your manufacturing equipment specifications. Ensure compatibility with the Gecko-Latch mating system before integration. Cross-reference the datasheet for precise reflow soldering profiles to maintain contact integrity and prevent thermal damage during the assembly process.
Selection Notes
Select this variant when vertical mounting and high-density connections are required within constrained board spaces. The 1.25mm pitch offers a balance between signal density and spacing. Consider the four-wall shielding feature if electromagnetic interference mitigation is necessary for adjacent circuit traces or sensitive components.
Part Context
This component belongs to the Gecko-Latch family, characterized by robust mechanical locking and compact form factors. It serves as a male header solution within the broader G125 product line, designed specifically for power-to-board applications requiring reliable electrical connectivity in demanding operational conditions.
Replacement Considerations
Compatible substitutes include G125-MS11205L1P and G125-MS11205M1P. Verify that alternative part numbers match the exact 1.25mm pitch, 12-position count, and surface mount termination style to ensure physical and electrical interchangeability.
