G125-MH25005L7R

Overview

The Harwin G125-MH25005L7R is a Gecko-Latch series header and wire housing component designed for board-to-board or wire-to-board applications. It features a 1.25 mm pitch with 50 positions arranged in a dual row configuration. The connector utilizes gold-plated phosphor bronze male pins and a green polyamide (PA) shrouded housing rated UL 94 V-0. It employs surface mount installation with a right-angle orientation and includes an unlatched locking mechanism. The unit supports a current rating of 2 A, operates within a temperature range of -65°C to +150°C, and offers an insulation resistance of 1 GOhms.

Feature Summary

• Integrates a Gecko-Latch system for secure mechanical retention without requiring latching mechanisms.
• Features a shrouded design to ensure precise alignment and protection during mating cycles.
• Utilizes gold-plated contacts on phosphor bronze bases to maintain reliable signal integrity.
• Supports automated assembly processes through its specific surface mount footprint.

Applications

• High-density electronic module interconnections
• Wire-to-board harness connections
• Industrial control system backplanes
• Automotive electronics sub-assemblies

Procurement Notes

Verify the exact suffix designation against the manufacturer's official documentation to confirm the specific surface mount termination style and pin length specifications. Ensure that the selected variant matches the required PCB layout dimensions and thermal profile capabilities for reflow soldering processes. Cross-reference the RoHS compliance status with the latest product release notes to guarantee adherence to current environmental regulations and material restrictions.

Selection Notes

Select this component when a low-profile, high-reliability connection is required for dense circuit layouts. The 1.25 mm pitch allows for significant I/O density within constrained spatial boundaries. Consider the right-angle orientation for vertical stacking or space-saving configurations. Validate that the 2 A current rating and 250V voltage limits align with the specific electrical requirements of the target application environment.

Part Context

This part belongs to the Harwin Gecko-Latch family, which specializes in robust, high-mating cycle connectors. The series is engineered for demanding environments where vibration resistance and secure locking are critical. The Gecko-Latch line typically combines standard connector geometries with proprietary locking features to enhance mechanical stability in industrial and transportation sectors.
