G125-MH13405L3R

Overview

The G125-MH13405L3R is a high-reliability header connector from the Harwin Gecko-Latch series, designed for demanding electronic applications. It features a 1.25 mm pitch and a 34-position configuration arranged in two rows (17+17). The component utilizes male pin contacts made of phosphor bronze with gold plating, housed in a green polyamide (PA) shell rated UL 94 V-0. Designed for through-hole mounting at a right angle, it incorporates a latching mechanism for secure board attachment. The connector supports a current rating of 2 A per contact and operates within a temperature range of -65°C to +150°C.

Feature Summary

• Integrated mechanical latching system ensures secure connection between mating components.
• Patented four-finger copper alloy contact design provides high reliability under extreme vibration conditions.
• Low-profile miniature package achieves significant space savings compared to standard high-performance connectors.

Applications

• High-reliability industrial electronics requiring robust mechanical retention
• Automotive systems operating under extreme vibration and wide temperature ranges
• Aerospace and defense equipment demanding compact, high-density interconnects
• Medical devices requiring verified biocompatibility and safety standards

Procurement Notes

Verify the specific suffix L3R against official datasheets to confirm the presence of the latching mechanism, as suffix variations define functional differences. Confirm RoHS compliance status via the manufacturer's declaration. Check lead times and availability directly with authorized distributors, as this component may have limited stock or discontinuation risks. Ensure PCB footprint matches the right-angle through-hole specification.

Selection Notes

Select this model when a secure mechanical lock is required for 34-position connections in space-constrained environments. The Gecko-Latch series offers superior vibration resistance compared to standard headers. Verify that the 2 A current rating and 150°C maximum temperature align with the application's thermal profile. Ensure the right-angle orientation fits the enclosure constraints.

Part Context

This part belongs to the Harwin Gecko-SL/Latch family, which uses a 1.25 mm pitch to minimize board space while maintaining high performance. The series is engineered for extreme environments, offering operation from -65°C to +150°C and resistance to Z-axis vibration up to 100g. The Gecko platform is widely used in industries requiring high-density, reliable connectivity in compact form factors.

Replacement Considerations

No direct public substitute part numbers are confirmed for this specific latched variant. Generic 1.25 mm pitch headers lack the integrated latching feature. Cross-reference with Harwin's Gecko-SL catalog for non-latched alternatives if locking is not critical, but verify mechanical compatibility carefully.
