Overview
The Harwin G125-MS13405L2R is a Gecko-Latch power-to-board header featuring a 1.25 mm pitch and 34 positions in a dual-row configuration. It utilizes male pin contacts made of phosphor bronze with gold plating, rated for 2 A current and up to 450 V voltage. Designed for surface mount (SMT) installation with solder termination, the connector operates within a temperature range of -65°C to +150°C. The housing is constructed from green polyamide (PA), providing an insulation resistance of 10 GOhms.
Feature Summary
- Gecko-Latch series design ensures secure mating retention
- Surface mount construction facilitates automated PCB assembly
- Gold-plated phosphor bronze contacts ensure reliable conductivity
Applications
- Industrial control systems requiring robust power distribution
- Automotive electronics operating in extreme temperatures
- Military equipment demanding high reliability
Procurement Notes
Verify the specific suffix 'L2R' against official Harwin documentation to confirm reel packaging and tape specifications. Ensure compatibility with mating sockets from the same Gecko-Latch family. Confirm RoHS compliance status through the manufacturer's latest environmental declarations before finalizing procurement orders.
Selection Notes
Select this component when a 1.25 mm pitch SMT male header is required for high-reliability power applications. The Gecko-Latch mechanism provides superior retention compared to standard headers. Verify that the 2 A per contact rating meets circuit requirements and that the -65°C to +150°C operational range suits the environmental conditions.
Part Context
This part belongs to the Harwin G125 Gecko-Latch family, designed for demanding environments. The series supports various configurations including different row counts and mounting styles. It is categorized under Power Connectors within the broader connector and interconnect device portfolio, emphasizing durability and performance.
Replacement Considerations
Consult Harwin's official cross-reference data for direct substitutes. Generic equivalents may not replicate the Gecko-Latch retention mechanism or the specific 1.25 mm pitch geometry. Verify stacking height compatibility if replacing in existing assemblies.
