G125-MH13405M4R

Overview

The Harwin G125-MH13405M4R is a 34-position male header from the Gecko-SL series, featuring a 1.25 mm pitch and two rows. Designed for through-hole right-angle installation with solder pin termination, it utilizes phosphor bronze contacts with gold plating. The connector supports a current rating of 2 A per contact and operates within a temperature range of -65°C to +150°C. It includes a jackscrew locking mechanism and is housed in green polyamide (PA) material rated UL 94 V-0.

Feature Summary

• High-reliability four-finger patented copper alloy contact design ensures stable performance under extreme vibration conditions.
• Integrated jackscrew locking system provides secure mechanical retention between mating connectors.
• Compact low-profile form factor achieves significant space savings compared to larger high-performance connector families.

Applications

• Demanding electronic product designs requiring high reliability in miniature packages
• Applications subject to extreme vibration environments such as Z-axis 100g testing
• Systems operating within wide temperature ranges from -65°C to +150°C

Procurement Notes

Verify component status carefully as this specific part number is listed as obsolete or end-of-life by the manufacturer. Confirm availability of alternative stock or final time buys if immediate procurement is required. Ensure compatibility with mating sockets within the same Gecko-SL series before ordering replacement units.

Selection Notes

Select this component when a right-angle through-hole male header with jackscrew locking is required for dense board layouts. The 1.25 mm pitch allows for higher density connections while maintaining 2 A current capacity. Consider the specific housing material and temperature ratings to ensure suitability for the target operational environment.

Part Context

This component belongs to the Harwin Gecko-SL family, which focuses on high-reliability interconnects for harsh environments. The series is characterized by its small footprint and robust contact engineering, designed to replace larger connectors like Micro-D while offering superior performance in terms of space efficiency and durability.

Replacement Considerations

As the part is obsolete, identify compatible alternatives within the Gecko-SL series that match the 34-position count, 1.25 mm pitch, and right-angle through-hole configuration. Verify that any substitute maintains the jackscrew locking feature and similar electrical ratings.
