G125-MH13405M3P

Overview

The Harwin G125-MH13405M3P is a Gecko-SL series power-to-board header designed for surface-mount technology. It features a dual-row configuration with 34 positions and a 1.25 mm pitch. The connector utilizes male pin contacts made of phosphor bronze with gold plating, rated for 2 A current. It employs a jackscrew locking mechanism for secure board attachment. The housing is constructed from green polyamide (PA) material, offering UL 94 V-0 flammability rating. Operating temperatures range from -65 °C to +150 °C.

Feature Summary

Features a jackscrew locking system for secure mechanical retention on the PCB.
Utilizes gold-plated phosphor bronze contacts for reliable electrical performance.
Designed with a low-profile shrouded housing for compact stacking applications.

Applications

High-density server backplanes
Industrial control systems
Telecommunications equipment

Procurement Notes

Verify the specific suffix against official Harwin documentation to confirm exact contact length and mounting style variations. Ensure compatibility with mating sockets within the same Gecko-SL family. Confirm RoHS compliance status through the manufacturer's latest declaration before integration into regulated environments.

Selection Notes

Select this component when a surface-mount solution with positive locking is required. The 1.25 mm pitch allows for high pin counts in limited space. Verify that the mating interface supports the jackscrew mechanism. Consider thermal requirements as the unit operates up to +150 °C. Ensure PCB layout accommodates the reverse fix mounting holes.

Part Context

This part belongs to the Harwin Gecko-SL family, known for robust interconnect solutions. The series emphasizes secure connections in vibration-prone environments. The G125 prefix indicates the 1.25 mm pitch standard. This specific model represents a male header variant suitable for vertical or angled board mounting depending on the full specification sheet.
