Overview
The Harwin G125-FS12005F2R is a Gecko-SL series power-to-board connector featuring a 1.25 mm pitch. It is a double-row, vertical surface-mount receptacle with 20 positions (2x10). The component utilizes female contacts and incorporates internally threaded Screw-Lok reverse fixings for secure board attachment. Designed for high-reliability applications, it supports automated assembly via tape and reel packaging.
Feature Summary
- Incorporates internally threaded Screw-Lok reverse fixings for enhanced mechanical retention
- Features a double-row vertical surface-mount design for compact integration
- Utilizes female socket contacts within a robust housing structure
Applications
- High-reliability industrial equipment interconnects
- Automotive electronic control unit power distribution
- Telecommunications infrastructure power modules
- Medical device internal power connections
Procurement Notes
Verify the specific suffix 'F2R' against current manufacturer documentation to confirm availability status, as this part may be classified as obsolete or restricted in certain regions. Ensure compatibility with existing PCB footprint designs and reflow soldering profiles before finalizing procurement orders.
Selection Notes
Select this component when a vertical, double-row SMT power connector with integrated screw-locking mechanisms is required. The 1.25 mm pitch allows for dense pin configurations suitable for space-constrained power delivery systems requiring high mechanical stability during operation.
Part Context
This connector belongs to the Harwin Gecko-SL family, engineered for demanding environments. The series emphasizes high performance and reliability through its unique Screw-Lok technology, which provides superior vibration resistance compared to standard surface-mount connectors without external hardware.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify if the variant G125-FS12005F2P serves as an alternative packaging option or if other Gecko-SL receptacles meet the specific mechanical and electrical requirements.
