Overview
The Harwin G125-MH13405L7R is a Gecko-SL series header and wire housing designed for surface-mount technology. It features a 1.25 mm pitch with 34 positions arranged in two rows. The connector utilizes right-angle through-hole solder pins for secure board attachment. Contact plating consists of gold over phosphor bronze, ensuring reliable conductivity. The unit operates within a temperature range of -65°C to +150°C and carries UL 94 V-0 flammability ratings.
Feature Summary
- Surface-mount design optimized for automated assembly processes
- Jackscrew locking mechanism provides secure mating retention
- High-density layout enables significant space savings on PCBs
Applications
- Automotive electronic control units
- Industrial instrumentation interfaces
- Telecommunications equipment backplanes
Procurement Notes
Verify the specific suffix L7R against official datasheets to confirm surface-mount compatibility and pin configuration. Confirm RoHS compliance status directly with the manufacturer or authorized distributors prior to procurement. Ensure storage conditions maintain integrity given the component's operational temperature specifications.
Selection Notes
Select this component when high-density interconnects are required alongside robust mechanical retention. The jack screw feature distinguishes it from standard headers by preventing accidental disengagement during vibration. Verify that the 1.25 mm pitch aligns with existing footprint designs and mating connector requirements.
Part Context
This part belongs to the Gecko-SL family, characterized by high-reliability performance in extreme environments. The series supports 2A per contact and withstands Z-axis vibration up to 100g. It offers a 35% space saving compared to Micro-D connectors while maintaining durable four-finger copper alloy contact technology.
Replacement Considerations
No public confirmed substitute part numbers are available for this specific model. Cross-reference with other Gecko-SL variants only if pin count and mounting style match exactly.
