G125-MV11005M1R

Overview

The Harwin G125-MV11005M1R is a Gecko-SL series male vertical through-board connector featuring a 1.25 mm pitch and 10 positions (5+5). It utilizes phosphor bronze contacts with gold plating for reliable signal transmission at 2 A per contact. The polyamide housing supports operation from -65°C to +150°C, offering high insulation resistance of 10 GOhms. Designed for pick-and-place assembly, it ensures secure board mounting via screw fixings with 5mm board mount studs.

Feature Summary

• High-reliability design supporting up to 1000 mating cycles
• Integrated screw-fixing mechanism with 5mm board mount studs for secure attachment
• Gold-plated phosphor bronze contacts optimized for signal integrity
• Automated pick-and-place compatible construction

Applications

• Industrial control systems requiring robust interconnects
• Power distribution modules needing secure board mounting
• Signal processing circuits demanding high reliability
• Automated manufacturing equipment interfaces

Procurement Notes

Verify the specific suffix 'M1R' confirms the tape-and-reel packaging format intended for automated surface-mount technology lines. Ensure the procurement specification explicitly includes the requirement for screw-fixing board mount studs, as this mechanical feature distinguishes the component from standard through-hole headers. Confirm compliance with RoHS directives before finalizing purchase orders.

Selection Notes

Select this component when a vertical through-board connector requires both high-density 1.25 mm spacing and mechanical stability provided by screw fixings. It is suitable for applications where automated assembly is preferred over manual insertion. Consider the 2 A current rating per contact for signal applications rather than high-power distribution. Verify that the PCB layout accommodates the necessary clearance for the integrated board mount studs.

Part Context

This part belongs to the Harwin Gecko-SL family, which specializes in high-reliability connectors for demanding environments. The series combines compact 1.25 mm pitch geometry with durable mechanical locking features. It serves as a bridge between standard through-hole connectivity and the need for enhanced physical security in vibration-prone industrial settings.
