Overview
The Harwin G125-MH22005L3R is a Gecko-Latch series header and wire housing designed for surface mount technology. It features a 1.25 mm pitch with a 2x10 position configuration, totaling 20 contacts. The component utilizes male pin contacts and is rated for 2A per contact. It operates within a temperature range of -65°C to +150°C. The unit weighs approximately 829 mg and is supplied in a reel package.
Feature Summary
- Surface mount design for automated assembly processes
- Patented four-finger copper alloy contact structure for high reliability
- Gecko-Latch mechanism ensures secure mating retention
Applications
- Extreme vibration environments requiring high-reliability connections
- Miniature electronic packages demanding space efficiency
- Applications operating within wide temperature ranges (-65°C to +150°C)
Procurement Notes
Verify the specific suffix 'R' indicates reel packaging versus 'P' for tape-and-reel or other variants. Confirm RoHS compliance status through official documentation. Ensure the 2x10 position count matches the required circuit density. Validate that the surface mount footprint aligns with the PCB design specifications before ordering.
Selection Notes
Select this component when surface mount assembly is required for the Gecko-Latch family. The 1.25 mm pitch offers significant space savings compared to larger connectors. Verify that the 2A current rating and 240V voltage limit meet the application's electrical requirements. Consider the horizontal installation style for board layout constraints.
Part Context
This part belongs to the Harwin G125 Gecko-Latch family, characterized by a 1.25 mm pin spacing. The series provides a 35% space saving over comparable high-performance connectors like Micro-D. It is engineered for durability under extreme conditions, including Z-axis vibration testing at 100g.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Cross-reference with other Harwin G125 series headers if mechanical compatibility is required.
