Overview
The G125-MV13405M3P is a Gecko-SL series power-to-board header manufactured by Harwin. It features a 1.25 mm pitch, 2-row configuration with 34 positions (2x17). Rated for 2 A current and 450 V voltage, it utilizes gold-plated beryllium copper pins in a green nylon housing. Designed for through-hole mounting at a straight angle, it operates within a temperature range of -65°C to +150°C.
Feature Summary
- Reverse fixing mechanism ensures secure board attachment
- High-reliability construction suitable for demanding environments
- Gold-plated contacts provide stable electrical performance
Applications
- Industrial control systems requiring high reliability
- Automotive electronics applications
- Power distribution boards
Procurement Notes
Verify the specific suffix M3P against official datasheets to confirm reverse fix functionality and pin configuration. Ensure compatibility with mating connectors within the Gecko-SL family. Confirm RoHS compliance status via manufacturer documentation before integration into regulated assemblies.
Selection Notes
Select this component for applications requiring compact 1.25 mm spacing with robust mechanical retention. The reverse fix design offers enhanced stability compared to standard headers. Verify that the 2 A current rating and 450 V insulation withstand voltage meet system requirements.
Part Context
This part belongs to the Harwin Gecko-SL series, designed for high-reliability interconnects. The series emphasizes durability and consistent performance in harsh conditions. The 1.25 mm pitch allows for dense circuit layouts while maintaining adequate clearance for power applications.
Replacement Considerations
Compatible mates include other Gecko-SL female connectors with matching 1.25 mm pitch. Verify row count and position alignment when substituting. Standard G125 series parts may differ in locking mechanisms.
