G125-MH11605L5P

Overview

The G125-MH11605L5P is a male header connector from the Harwin Gecko-Latch series, featuring 16 positions arranged in a dual-row configuration. It utilizes a 1.25 mm pitch and is designed for right-angle through-hole termination on printed circuit boards. The connector supports a rated current of 2 A and operates within a temperature range of -65°C to +150°C. Constructed with beryllium copper contacts gold-plated for reliability, it employs a nylon housing. This component requires specialized tooling for mating and disengagement, ensuring secure board-to-board or cable-to-board connections.

Feature Summary

• Gecko-Latch mechanism requiring special tooling for engagement
• Right-angle horizontal orientation for space-efficient mounting
• Gold-plated beryllium copper contacts for signal integrity
• High-temperature resistant nylon housing material

Applications

• Board-to-board interconnects in compact electronic assemblies
• Cable-to-board connections in industrial control systems
• High-density signal routing in telecommunications equipment
• Automotive electronics modules requiring secure latching

Procurement Notes

Verify that the specific part number includes the L5P suffix, which denotes the tape and reel packaging format. Confirm compatibility with the required Harwin Gecko mating tools, as standard insertion methods are not applicable due to the latch design. Ensure the receiving facility has appropriate handling procedures for the right-angle orientation and through-hole soldering requirements specified in the datasheet.

Selection Notes

Select this component when a low-profile, high-reliability connection is needed in constrained spaces. The right-angle design facilitates efficient PCB layout compared to vertical headers. Consider the necessity of the Gecko latch system for vibration resistance and the requirement for dedicated assembly tooling. Verify that the 1.25 mm pitch aligns with the mating connector specifications and that the 2 A current rating meets the circuit load requirements.

Part Context

This connector belongs to the Harwin Gecko family, known for its robust latching mechanism and compact form factor. The G125 series specifically targets applications demanding high density and reliable performance in harsh environments. The male pin configuration allows for versatile integration into various electronic systems where secure, tool-assisted connections are prioritized over manual plug-and-play convenience.

Replacement Considerations

Direct substitutes must match the 16-position count, 1.25 mm pitch, right-angle orientation, and Gecko-Latch mechanism. Generic 1.25 mm headers without the latching feature are not suitable replacements due to differing mechanical retention properties. Verify that any alternative maintains the same electrical ratings and thermal characteristics.
