G125-MH22005L2R

Overview

The G125-MH22005L2R is a male pin header from the Harwin Gecko-Latch series, designed for board-to-board or cable connections. It features a 1.25 mm pitch and a 2x10 position configuration (20 positions total). The connector utilizes a shrouded design with right-angle through-hole mounting and solder pin termination. Contacts are made of phosphor bronze with gold plating, rated for 2 A current. The housing is constructed from green polyamide (PA) material, offering UL 94 V-0 flammability rating. Operating temperature ranges from -65°C to +150°C.

Feature Summary

• Gecko-Latch mechanical locking system ensures secure mating
• Shrouded housing design provides alignment and protection
• Right-angle through-hole mounting facilitates compact PCB layouts
• Gold-plated phosphor bronze contacts ensure reliable conductivity

Applications

• Board-to-board interconnects in industrial equipment
• Cable-to-board connections in automotive systems
• High-reliability applications requiring vibration resistance
• Compact electronic devices needing space-saving connectors

Procurement Notes

Verify the specific suffix 'L2R' against the official Harwin datasheet to confirm it denotes the correct right-angle through-hole variant within the Gecko-Latch family. Ensure compatibility with mating sockets from the same series. Check RoHS compliance status on the manufacturer's website prior to ordering, as regulatory updates may occur.

Selection Notes

Select this component when a right-angle male header with a 1.25 mm pitch is required for high-density applications. The Gecko-Latch mechanism offers superior retention compared to standard headers. Verify that the PCB footprint matches the 2x10 configuration and that the right-angle orientation aligns with the assembly constraints. Confirm thermal requirements fall within the -65°C to +150°C range.

Part Context

This part belongs to the Harwin G125 Gecko series, known for its high reliability in extreme environments. The series supports various configurations including vertical and right-angle options. The Gecko-Latch variant specifically incorporates a patented four-finger contact design and mechanical latching for enhanced performance under vibration and shock conditions.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Cross-referencing requires matching pitch, row count, and locking mechanism specifications.
