Overview
The Harwin G125-MH12005L1R is a Gecko-Latch series male header connector designed for wire-to-board applications. It features a 1.25 mm pitch with 20 positions arranged in a dual row configuration. The component utilizes right-angle through-hole solder pin termination and includes a latch lock mechanism for secure mating. Constructed with phosphor bronze contacts plated with gold, it supports a current rating of 2 A and operates within a temperature range of -65°C to +150°C. The housing is made of green nylon rated UL 94 V-0.
Feature Summary
- Integrated latch lock mechanism ensures secure connection stability
- Right-angle through-hole mounting facilitates PCB layout flexibility
- Gold-plated phosphor bronze contacts provide reliable conductivity
Applications
- Wire-to-board interconnections
- Signal transmission in electronic assemblies
- Industrial control system interfaces
Procurement Notes
Verify the specific suffix 'R' indicates tape and reel packaging when ordering. Confirm RoHS compliance status via official documentation prior to integration. Ensure compatibility with mating sockets from the same Gecko-Latch family. Check for any recent engineering change notices affecting dimensions or materials.
Selection Notes
Select this part for applications requiring high-density connections with secure latching. The right-angle design suits space-constrained boards where vertical headers are impractical. Verify that the 2 A current rating meets circuit requirements. Consider the 3.3 mm contact length for appropriate cable strain relief needs.
Part Context
This component belongs to Harwin's Gecko-Latch series, known for micro-miniature signal connectors. The G125-MH12005L1R specifically addresses the need for robust, latched connections in compact electronics. It complements other variants in the series offering different pin counts and mounting styles.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided data. Direct replacement requires identical mechanical and electrical specifications from the Gecko-Latch family.
