Overview
The Harwin G125-MS11205M2P is a Gecko-SL series power-to-board connector designed for surface-mount assembly. It features a 12-position, two-row male header configuration with a 1.25 mm pitch. The unit utilizes gold-plated phosphor bronze contacts housed in a green polyamide (PA) shell. Rated for 2 A current and 250 V voltage, it supports a straight mounting angle with solder pin termination. The component operates within a temperature range of -65°C to +150°C and includes a 3.0 mm board mount jack screw feature.
Feature Summary
- Surface-mount vertical design for automated PCB assembly
- Integrated jack screw mechanism for secure board mounting
- High-density two-row layout with 1.25 mm spacing
Applications
- Industrial control system power distribution
- Telecommunications equipment backplanes
- Automotive electronic module interconnects
Procurement Notes
Verify the specific ordering suffix against the manufacturer datasheet to confirm contact plating thickness and housing material variations. Ensure compatibility with the mating socket part numbers listed in the official Harwin selection guide. Confirm RoHS compliance status through the latest product compliance declaration provided by the supplier.
Selection Notes
Select this component when a low-profile, high-reliability power connection is required for space-constrained designs. The jack screw feature provides mechanical stability superior to standard SMT headers. Consider the 1.25 mm pitch density for maximizing circuit capacity while maintaining adequate electrical clearance between rows.
Part Context
This part belongs to the Gecko-SL family, which emphasizes compact form factors for modern electronics. The series offers various row counts and termination styles to support diverse board-to-board and wire-to-board applications. The G125 designation indicates the 1.25 mm pitch standard used across the product line.
Replacement Considerations
Direct substitutes include other Harwin Gecko-SL variants with identical 1.25 mm pitch and 12-position configurations. Verify that alternative parts maintain the same jack screw mounting style and surface-mount footprint dimensions to ensure mechanical interchangeability without PCB rework.
