G125-MH11205L1R

Overview

The G125-MH11205L1R is a Gecko-Latch series header manufactured by Harwin Inc. It features a 1.25 mm pitch with 20 positions arranged in a dual-row configuration. The connector utilizes male pin contacts made of phosphor bronze with gold plating, rated for 2 A current and 250 V voltage. Designed for through-hole mounting at a right angle, it includes a latch lock mechanism for secure board retention. The housing is constructed from green nylon (PA) with a UL 94 V-0 flammability rating, supporting an operating temperature range of -65°C to +150°C.

Feature Summary

• Features a patented four-finger copper alloy contact design ensuring high reliability under extreme vibration conditions.
• Incorporates a mechanical latch lock system to secure the connector firmly to the printed circuit board.
• Provides a low-profile form factor that achieves significant space savings compared to larger high-performance connectors.

Applications

• Automotive electronics interconnects
• General industrial equipment connections
• Stacking applications requiring secure board-to-board or cable-to-board links

Procurement Notes

Verify the specific suffix codes against the official Harwin datasheet to confirm exact pin count, row configuration, and termination style. Ensure the selected variant matches the required mounting orientation and locking mechanism for the target PCB layout. Cross-reference the RoHS compliance status and material composition data prior to final procurement approval.

Selection Notes

Select this component when a robust latching mechanism is required for high-vibration environments. The 1.25 mm pitch allows for dense packing while maintaining 2 A per contact ratings. Consider the right-angle through-hole profile for vertical stacking or restricted height applications where standard headers are unsuitable.

Part Context

This part belongs to the Harwin Gecko-Latch family, designed for demanding applications requiring high reliability. The series is characterized by its miniature size, offering 35% space savings over competitors like Micro-D. It is engineered to withstand Z-axis vibrations up to 100g and operates across a wide thermal range.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Evaluate cross-compatibility based on matching 1.25 mm pitch, 20-position dual-row layout, and latching features if sourcing alternatives.
