Overview
The Harwin G125-MS12605L3P is a Gecko-Latch series PCB header featuring 26 positions (2x13) with a 1.25 mm pitch. It utilizes phosphor bronze contacts gold-plated for conductivity, housed in polyamide insulation rated for 250 V and 2 A current. Designed for surface mount technology, the connector operates within a temperature range of -65°C to +150°C. The straight male pin configuration includes solder retention features and pick-and-place compatibility for automated assembly processes.
Feature Summary
- Integrated latch mechanism utilizing surface mount hold-down areas to provide additional strain relief during board-to-board connections.
- Designed for automated manufacturing with specific pick-and-place capabilities and solder retention properties.
- Constructed from halogen-free glass-filled polyamide insulation to support high-temperature reliability.
Applications
- Board-to-board interconnections requiring secure mechanical latching
- High-density power distribution modules
- Automated SMT assembly lines
Procurement Notes
Verify the exact contact count and latch configuration against the official datasheet before integration. Confirm that the surface mount footprint matches the target PCB design. Ensure the operating environment remains within the specified thermal limits to maintain connection integrity and electrical performance standards.
Selection Notes
Select this component when a secure, latched surface mount solution is required for high-density applications. The 1.25 mm pitch allows for compact layouts while maintaining adequate spacing. Consider the gold plating for corrosion resistance and the halogen-free material for compliance with environmental regulations.
Part Context
This part belongs to the Gecko-Latch family, which emphasizes secure mechanical retention for surface mount headers. The series supports various pin counts and configurations, offering a robust alternative to standard non-latching connectors in vibration-prone or high-reliability environments.
Replacement Considerations
Compatible counterparts include other Gecko-Latch variants such as G125-MS12005L3P for different pin counts. Verify that substitute parts maintain the same 1.25 mm pitch, surface mount orientation, and latching mechanism specifications.
