Overview
The Harwin G125-MS13405L2P is a Gecko-Latch series power-to-board header featuring a 1.25 mm pitch and 34 positions in a dual-row configuration. It utilizes male pin contacts with gold plating on phosphor bronze, rated for 2 A current. Designed for surface mount (SMD/SMT) installation at a straight angle, 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 mechanism ensures secure mating retention
- Surface mount termination facilitates automated assembly
- High-temperature polyamide housing supports thermal stability
Applications
- Industrial control systems requiring robust power distribution
- Automotive electronics modules demanding high reliability
- Consumer appliance mainboards needing secure connections
Procurement Notes
Verify the specific suffix L2P against official datasheets to confirm packaging details and reel specifications. Ensure compatibility with mating female connectors within the same Gecko-Latch family. Confirm RoHS compliance status through manufacturer documentation prior to integration into regulated environments.
Selection Notes
Select this component when surface mount technology is required for high-density power applications. The 1.25 mm pitch allows for compact board layouts while maintaining adequate spacing. Verify that the operating environment stays within the specified -65 C to +150 C range to ensure long-term performance and material integrity.
Part Context
This part belongs to the Harwin G125 Gecko-Latch family, designed for power-to-board interconnects. It complements other variants in the series by offering a specific position count and surface mount profile. The series is characterized by its latching feature and high-temperature capabilities, suitable for demanding electronic assemblies.
Replacement Considerations
Direct substitutes include other G125-MS series headers with matching 34-position counts and 1.25 mm pitch. Verify mechanical dimensions and latching force requirements before substitution. Cross-reference mating female parts to ensure proper engagement and retention characteristics.
