G125-MH10605L5R

Overview

The G125-MH10605L5R is a male header connector from the Harwin Gecko-SL series, designed for through-hole mounting. It features a 6-position configuration with a 1.25 mm (0.049 inch) pitch and two rows. The contacts are gold-plated phosphor bronze pins rated for 2 A at 450 V. The housing is green polyamide (PA4T), offering a UL 94 V-0 flammability rating and an operating temperature range of -65°C to +150°C. This specific variant is supplied in tape and reel packaging.

Feature Summary

• Jackscrew locking mechanism provides secure board-to-board or cable connections.
• Reverse fix design allows for flexible orientation during assembly.
• Polarized keying prevents incorrect mating between components.

Applications

• Industrial control systems requiring reliable signal transmission
• Automotive electronics modules
• Consumer appliance internal wiring

Procurement Notes

Verify the exact suffix 'L5R' confirms the tape and reel packaging format, as standard bulk versions may differ. Ensure compatibility with the corresponding female socket series, such as the G125-FV or G125-FS counterparts, to maintain proper stacking height and mechanical alignment. Confirm RoHS compliance status for your specific region before finalizing procurement orders.

Selection Notes

Select this component when a right-angle or horizontal male header with jackscrew retention is required for space-constrained designs. The 1.25 mm pitch supports high-density layouts while maintaining robust electrical performance. Consider the reverse fix feature if assembly flexibility is needed. Verify that the 2 A current rating meets the circuit requirements and that the through-hole termination suits the PCB manufacturing capabilities.

Part Context

This part belongs to the Harwin Gecko-SL family, known for micro-miniature connectors with high reliability. The G125 series utilizes a unique jackscrew system for secure mating. As a male pin header, it serves as the stationary counterpart to female sockets in board-to-board or cable assemblies within the broader interconnect ecosystem.

Replacement Considerations

No direct public substitute part numbers are confirmed for this specific model. Generic 1.25 mm pitch headers lack the proprietary jackscrew locking mechanism and reverse fix geometry, potentially compromising mechanical security and assembly flexibility.

FAQ

What is the locking mechanism used in this connector?

The G125-MH10605L5R utilizes a jackscrew (screw-lock) system to secure the connection between the male header and female socket.

Is this connector polarized?

Yes, the connector includes polarized keying features to prevent incorrect mating orientations.
