G125-MH11605M4R

Overview

The Harwin G125-MH11605M4R is a Gecko-SL series male plug connector featuring 16 positions arranged in a dual in-line (8+8) configuration. It utilizes a 1.25 mm pitch and operates with right-angle through-hole mounting. The contacts are gold-plated phosphor bronze pins rated for 2 A current, housed in green polyamide insulation. Designed for board-to-board connections, it employs a jackscrew locking mechanism and functions within a temperature range of -65 °C to +150 °C.

Feature Summary

• Integrates a jackscrew locking system for secure mechanical retention during vibration
• Features right-angle through-hole termination for compact vertical board integration
• Utilizes gold-plated phosphor bronze contacts for reliable signal transmission

Applications

• Board-to-board interconnects in industrial control systems
• Signal routing in high-reliability aerospace electronics
• Power distribution modules requiring secure screw-lock retention

Procurement Notes

Verify the specific suffix M4R against official Harwin documentation to confirm the tape-and-reel packaging format and right-angle orientation. Ensure the jackscrew locking feature aligns with the mechanical constraints of the target assembly. Cross-reference the polyamide housing material and gold plating specifications with the approved datasheet to guarantee compliance with environmental and electrical requirements.

Selection Notes

Select this component when a secure, non-vibrating connection is required for 16-position signal lines. The right-angle form factor suits space-constrained vertical layouts. The jackscrew mechanism provides superior retention compared to standard snap-fit headers. Verify that the 1.25 mm pitch matches the mating connector footprint and that the through-hole soldering process accommodates the specified pin length.

Part Context

This part belongs to the Harwin Gecko-SL family, designed for high-reliability applications. The series emphasizes robust mechanical locking and stable electrical performance in demanding environments. The G125-MH11605M4R specifically addresses needs for secure, angled connections in dense electronic assemblies where vibration resistance is critical.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Consult Harwin's official cross-reference tools or authorized distributors for verified alternatives matching the 1.25 mm pitch, 16-position count, and jackscrew locking mechanism.
