Overview
The G125-MH12005L5R is a Gecko-Latch male header manufactured by Harwin Inc. It features a 1.25 mm pitch and a dual-row configuration with 20 positions. Designed for right-angle through-hole mounting, the connector utilizes solder pin termination. The contacts are gold-plated phosphor bronze pins housed in green nylon insulation. It supports a current rating of 2 A and operates within a temperature range of -65°C to +150°C. The unit includes board lock retention and is supplied in tape-and-reel packaging.
Feature Summary
- Gecko-Latch locking mechanism provides secure horizontal connection
- Right-angle through-hole design facilitates compact PCB layout
- Gold-plated phosphor bronze contacts ensure reliable signal transmission
- Board lock feature secures the connector firmly to the substrate
Applications
- Wire-to-board interconnections
- High-density electronic assemblies
- Industrial control systems
- Automotive electronics modules
Procurement Notes
Verify the specific suffix 'L5R' against official Harwin documentation to confirm right-angle through-hole orientation and tape-and-reel packaging format. Ensure compatibility with mating sockets from the same Gecko-Latch series. Confirm RoHS compliance status and material composition details prior to final procurement decisions.
Selection Notes
Select this component when a low-profile, high-density connection is required on a printed circuit board. The right-angle form factor optimizes space utilization in constrained enclosures. Verify that the mating interface requires the specific Gecko-Latch horizontal locking style rather than vertical or screw-lock variants.
Part Context
This part belongs to the Harwin Gecko-Latch family, which specializes in micro-miniature connectors. The series is engineered for applications demanding high reliability and robust mechanical retention. The Gecko-Latch variant specifically addresses needs for secure horizontal mating without additional fasteners.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Cross-reference with other Harwin Gecko-Latch headers only if pin count, pitch, and locking mechanism match exactly.
