Overview
The G125-MH15005M3R is a Gecko-SL male header connector manufactured by Harwin Inc. It features a 1.25 mm pitch and a 2-row, 50-position configuration. Designed for right-angle through-hole mounting, the unit utilizes solder pin termination with gold-plated phosphor bronze contacts rated for 2 A current. The housing is constructed from green polyamide (PA) plastic with UL 94 V-0 flammability rating. Operating temperatures range from -65 °C to +150 °C. This specific variant is supplied in tape-and-reel packaging.
Feature Summary
- Patented four-finger copper alloy contact design ensures high reliability under extreme vibration conditions.
- Compact low-profile form factor provides significant space savings compared to Micro-D connectors.
- Jackscrew locking mechanism secures mating connections for robust signal integrity.
Applications
- High-density electronic product designs requiring miniature packages
- Applications demanding performance in extreme temperature environments
- Systems subject to severe vibration and shock loads
Procurement Notes
Verify that the ordering suffix 'R' confirms tape-and-reel packaging rather than bulk or tray formats. Confirm the specific reel quantity matches production requirements. Ensure the right-angle orientation aligns with PCB layout constraints. Validate RoHS compliance status prior to integration into regulated assemblies.
Selection Notes
Select this component when high-density interconnects are required within strict spatial limits. The 1.25 mm pitch allows for increased pin counts without increasing footprint. Choose the right-angle version for board-to-board stacking or edge-mounting scenarios where vertical clearance is restricted.
Part Context
This part belongs to the Harwin Gecko-SL family of micro-miniature connectors. The series is engineered for demanding applications, offering a 35% space saving over traditional high-performance alternatives. The family supports various configurations including headers, housings, and cable assemblies.
Replacement Considerations
No public confirmed substitute part numbers are available for this specific model. Evaluate other Gecko-SL variants for similar pitch and position counts if direct replacement is necessary.
