G125-MH23405L2R

Overview

The Harwin G125-MH23405L2R is a Gecko-Latch series header and wire housing designed for surface-mount technology. It features a 1.25 mm pitch with a 2x10 position configuration, totaling 20 contacts. The component utilizes male pin terminals with gold plating on phosphor bronze substrates. Rated for 2.8 A current and 250 V/450 V voltage, it operates within a temperature range of -65°C to +150°C. The housing is constructed from polyamide (PA) with UL 94 V-0 flammability rating. This reel-packaged connector ensures reliable board-to-board or cable connections in compact electronic assemblies.

Feature Summary

• Gecko-Latch mechanical locking system provides secure connection retention
• Surface-mount design facilitates automated pick-and-place assembly
• Gold-plated phosphor bronze contacts ensure stable signal transmission
• Polyamide housing offers high thermal stability and flame resistance

Applications

• Compact signal processing modules
• Board-to-board interconnects in dense PCB layouts
• Industrial control systems requiring secure latching
• Automotive electronics with space constraints

Procurement Notes

Verify the specific suffix 'L2R' confirms the reel packaging format suitable for automatic machine placement. Ensure compatibility with the corresponding Gecko-Latch mating socket. Confirm that the 2x10 position count matches the target circuit design requirements before finalizing procurement orders.

Selection Notes

Select this model when a low-profile, surface-mount solution with positive latching is required. The 1.25 mm pitch allows for high-density routing compared to standard headers. Consider the 2.8 A current rating for power distribution needs. Verify that the horizontal mounting style fits the available board real estate and clearance constraints.

Part Context

This component belongs to the Harwin Gecko-Latch family, which emphasizes secure mechanical engagement through a unique latch mechanism. The series is engineered for applications demanding high reliability and vibration resistance. The G125-MH23405L2R specifically addresses the need for robust, space-efficient interconnects in modern electronic manufacturing environments.

Replacement Considerations
