Overview
The Harwin G125-FS12605F2R is a Gecko-SL series female receptacle connector designed for surface mount technology. It features a double-row, straight vertical configuration with 26 positions (13+13 contacts). The component utilizes a 1.25 mm pitch and incorporates internally threaded Screw-Lok locking mechanisms for secure mating. Constructed with gold-plated phosphor bronze contacts and a green polyamide housing, it supports through-hole or SMT board mounting styles depending on the specific variant configuration within the series.
Feature Summary
- Double-row vertical surface mount design for high-density applications
- Integrated Screw-Lok jackscrew locking system for secure connection retention
- Gold-plated contacts ensure reliable electrical performance in harsh environments
Applications
- Industrial control systems requiring robust board-to-board connections
- Automotive electronics demanding high vibration resistance
- Medical devices needing reliable signal transmission
Procurement Notes
Verify the exact suffix against the official datasheet to confirm orientation and packaging. Ensure compatibility with the mating male header from the same Gecko-SL family. Check RoHS compliance status via the manufacturer's documentation before integration into regulated products.
Selection Notes
Select this part for applications requiring vertical SMT mounting with secure mechanical locking. Confirm the 1.25 mm pitch matches the PCB footprint. Ensure the mating connector is a compatible male header with matching Screw-Lok features for proper engagement.
Part Context
This component belongs to the Harwin Gecko-SL family, known for its screw-locking mechanism that prevents accidental disconnection. The series offers various configurations including right-angle and different contact counts, all sharing the same 1.25 mm pitch and locking philosophy for system consistency.
Replacement Considerations
No direct public substitute part numbers are confirmed. Cross-reference only with other Harwin Gecko-SL female connectors of identical pitch and row count to maintain mechanical and electrical compatibility.
