Overview
The Harwin G125-MV12005M1R is a Gecko-SL power-to-board connector featuring a 1.25 mm pitch and a 10+10 contact configuration. It utilizes a male vertical through-board design with screw fixings and 5 mm board mount studs for secure attachment. The contacts are gold-plated phosphor bronze, rated for 2 A per pin. This component supports pick-and-place assembly via tape and reel packaging.
Feature Summary
- Vertical through-board mounting with integrated screw fixings and 5 mm board mount studs
- Gecko-SL series design utilizing patented four-finger copper alloy contacts
- Gold-plated contacts ensuring reliable performance in extreme vibration conditions
Applications
- Power distribution in high-reliability electronic systems
- Board-to-board connections requiring robust mechanical retention
- Applications subject to extreme vibration environments
Procurement Notes
Verify the specific ordering suffix against the official Harwin datasheet to confirm the exact contact count, plating thickness, and packaging type. Ensure the selected variant matches the required board thickness and stud length specifications for the intended application.
Selection Notes
Select this connector when a vertical power interface with mechanical screw fixation is required. The 1.25 mm pitch allows for significant space savings compared to larger pitch connectors. Verify compatibility with mating sockets within the Gecko-SL family before integration.
Part Context
This component belongs to the Harwin Gecko-SL family, designed for demanding applications requiring high reliability in miniature packages. The series offers a 35% space saving over other high-performance connectors like Micro-D and is engineered to withstand extreme temperatures and vibration.
Replacement Considerations
Compatible substitutes include other variants within the Harwin G125-MS (SMT) or G125-MH (Through-hole Header) series that share the 1.25 mm pitch and Gecko-SL mating interface, provided the mounting style aligns with the design requirements.
