G125-MS13405L3R

Overview

The Harwin G125-MS13405L3R is a Gecko-Latch series power-to-board connector designed for vertical surface-mount applications. It features a 1.25 mm pitch with 34 positions arranged in two rows. The component utilizes male pin contacts made of phosphor bronze with gold plating, housed in polyamide (PA). Rated for 2 A current and voltages up to 250 V or 450 V, it operates within a temperature range of -65 C to +150 C. The connector offers an insulation resistance of 10 GOhms and provides mated stacking heights of 7.35 mm, 7.45 mm, and 7.8 mm.

Feature Summary

• Vertical surface-mount design for compact board integration
• Gecko-Latch mechanism ensures secure mating retention
• High-reliability construction suitable for demanding environments

Applications

• Aviation systems requiring high reliability
• Space and defense electronics
• Motorsport data acquisition units

Procurement Notes

Verify the specific ordering suffix against official Harwin documentation to confirm contact configuration and packaging type. Ensure compatibility with mating female housings from the same Gecko-Latch family. Confirm that the vertical SMT footprint matches the target PCB layout constraints before finalizing procurement orders.

Selection Notes

Select this component when vertical mounting space is limited but high current capacity is required. The 1.25 mm pitch allows for dense pin counts while maintaining robust electrical ratings. Consider the available stacking heights to ensure proper clearance with adjacent components on the assembly.

Part Context

This part belongs to the Harwin Gecko G125 series, which focuses on high-reliability interconnects. The series is engineered for challenging environments where failure is not acceptable. The Gecko-Latch variant specifically adds mechanical locking features to prevent accidental disconnection during vibration or shock.

Replacement Considerations

Direct substitutes are not explicitly listed in public documentation. Verify cross-compatibility with other G125-MS variants sharing the same 1.25 mm pitch and 34-position count. Ensure mating housing part numbers align with the selected stack height requirements.
