Overview
The G125-MS11605M2R is a Gecko SL series male header connector designed for surface mount technology. It features a 1.25 mm pitch with 16 positions arranged in a dual-row configuration. The contacts are constructed from phosphor bronze and gold-plated, supporting a current rating of 2 A and voltage ratings up to 450 V. The housing utilizes green polyamide (PA4T) material, offering UL94 V-0 flammability. Operating temperatures range from -65°C to +150°C, with an insulation resistance of 1 GOhms.
Feature Summary
- Surface mount design with integrated mounting flanges for secure PCB attachment
- Polarization keys prevent incorrect mating alignment between components
- Gold-plated phosphor bronze contacts ensure reliable electrical conductivity
- High-temperature resistant polyamide housing suitable for harsh environments
Applications
- Board-to-board interconnections in compact electronic assemblies
- Power distribution modules requiring high current density
- Industrial control systems operating within extended temperature ranges
- Telecommunications infrastructure equipment
Procurement Notes
Verify the specific suffix 'M2R' against official Harwin documentation to confirm reel packaging and pin configuration. Ensure compatibility with mating sockets regarding polarization keys and stacking height. Confirm RoHS compliance status through the manufacturer's latest environmental declarations before final procurement decisions.
Selection Notes
Select this component when space constraints require a low-profile 1.25 mm pitch connector with surface mount capabilities. The dual-row layout maximizes connection density while maintaining 2 A current capacity per contact. Consider the 450 V rating for applications exceeding standard low-voltage thresholds.
Part Context
This part belongs to the Harwin Gecko SL family, engineered for high-density power and signal transmission. The series emphasizes robust mechanical retention and precise alignment through unique keying features. It serves as a critical interface solution in modern electronics where reliability and miniaturization are paramount.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify cross-compatibility with existing mating connectors based on pitch, row count, and polarization key placement before considering alternatives.
