Overview
The Harwin G125-FV12605F2R is a Gecko-SL series power-to-board connector designed for vertical through-hole mounting. It features a female socket configuration with 26 positions arranged in two rows, utilizing a 1.25 mm pitch. The component is rated for 2 A current and supports voltage ratings of 250 V and 450 V. Constructed with copper alloy contacts featuring gold plating, it ensures reliable conductivity. The housing is made from green nylon (PA4T), offering halogen-free insulation. It operates within a temperature range of -65°C to +150°C and includes reverse fixing tape packaging for automated assembly.
Feature Summary
- Patented four-finger contact design maintains electrical connection under high vibration and shock conditions
- Vertical through-hole solder pin termination facilitates direct board integration
- Reverse fixing tape packaging enables efficient pick-and-place automated manufacturing
Applications
- Industrial control systems requiring high reliability
- Automotive electronics subject to mechanical stress
- Power distribution modules in compact enclosures
Procurement Notes
Verify the specific suffix 'F2R' against official datasheets to confirm the inclusion of reverse fixing tape packaging, as this affects handling procedures. Ensure compatibility with mating male headers from the same Gecko-SL family. Confirm RoHS and REACH compliance status via the manufacturer's latest documentation before finalizing procurement orders.
Selection Notes
Select this component when vertical orientation and robust vibration resistance are critical. The 1.25 mm pitch allows for dense power routing in limited spaces. Verify that the mating connector supports the required 2 A current rating per contact. Consider the operating temperature range up to +150°C for high-heat environments.
Part Context
This part belongs to the Harwin Gecko-SL G125 family, known for high-reliability interconnects. The series utilizes a unique locking mechanism and patented contact technology. It is distinct from standard connectors by its ability to withstand harsh mechanical environments while maintaining low contact resistance.
Replacement Considerations
No public confirmed substitute part numbers are available. Direct replacement requires identical specifications regarding pitch, contact count, and mounting style.
FAQ
What is the purpose of the reverse fixing tape?
The reverse fixing tape secures the components during shipping and enables automated pick-and-place assembly processes.
How does the contact design handle vibration?
The patented four-finger contact design maintains electrical continuity even under high vibration and shock conditions.
