Overview
The Harwin G125-MV12605M1R is a Gecko-SL series power-to-board connector designed for vertical through-board mounting. It features a 1.25 mm pitch with 26 positions (13+13) in a dual inline configuration. The component utilizes gold-plated phosphor bronze contacts and includes screw fixings with 5mm board mount studs for secure attachment. Rated for 2 A current, it supports pick-and-place assembly via tape and reel packaging.
Feature Summary
- Vertical through-board mounting design with integrated screw fixings
- Gold-plated contacts ensuring reliable electrical performance
- Compatible with automated pick-and-place manufacturing processes
Applications
- Industrial control systems requiring robust power connections
- Automotive electronics applications
- High-reliability server infrastructure hardware
Procurement Notes
Verify the specific suffix 'R' confirms tape and reel packaging suitable for automated surface mount technology lines. Ensure compatibility with mating female sockets within the same Gecko-SL family. Confirm that the 5mm board mount stud length meets the mechanical clearance requirements of the target enclosure design before finalizing procurement orders.
Selection Notes
Select this variant when vertical orientation and high mechanical stability are required. The screw-fixing mechanism provides superior retention compared to standard press-fit connectors. Consider the 1.25 mm pitch density for space-constrained layouts while maintaining the 2 A current carrying capacity per contact.
Part Context
This part belongs to the Harwin Gecko-SL family, known for high reliability in harsh environments. It complements other Gecko-SL headers and cable assemblies, forming a complete interconnect solution. The series is widely used in demanding sectors where vibration resistance and long-term durability are critical specifications.
Replacement Considerations
Direct substitutes include other Harwin Gecko-SL vertical headers with identical 26-position counts and 1.25 mm pitch. Verify that any alternative maintains the same screw-fixing mounting style and gold plating specification to ensure mechanical and electrical interchangeability.
