G125-MH12605L3R

Overview

The Harwin G125-MH12605L3R is a Gecko-Latch series header connector featuring a 1.25 mm pitch and 26 positions arranged in a dual-row configuration. Designed for through-hole mounting, it utilizes gold-plated phosphor bronze contacts with a 2 A current rating. The shrouded housing is constructed from green polyamide (PA4T) material, offering UL 94 V-0 flammability resistance. It operates within a temperature range of -65°C to +150°C and includes a latch lock mechanism for secure mating.

Feature Summary

• Integrates a mechanical latch lock system to ensure secure connection retention during operation.
• Features a shrouded design that protects contacts and guides mating connectors for precise alignment.
• Utilizes gold-plated phosphor bronze contacts to provide reliable electrical conductivity and corrosion resistance.

Applications

• Wire-to-board interconnections
• Board-to-board connections
• General electronic equipment requiring secure locking headers

Procurement Notes

Verify the specific suffix 'L3R' against the manufacturer's official datasheet to confirm the exact pin length, reel packaging type, and RoHS compliance status. Ensure the procurement documentation matches the Gecko-Latch series specifications rather than generic Gecko-SL variants. Cross-reference the part number with authorized distributors to confirm availability and authenticity before finalizing orders.

Selection Notes

Select this component when a secure locking mechanism is required for 1.25 mm pitch applications. It is suitable for environments demanding high vibration resistance due to the latch feature. Consider the through-hole mounting style and right-angle orientation for PCB layout constraints. Verify that the 2 A current rating and operating temperature range meet the specific circuit requirements.

Part Context

This part belongs to the Harwin Gecko-Latch family, which emphasizes secure connectivity solutions. The Gecko series is widely recognized for its compact form factor and robust mechanical features. This specific model represents a dual-row header variant designed for higher density connections while maintaining the series' standard reliability and performance characteristics.

Replacement Considerations

Direct substitutes within the same series include G125-MH12605M4R, which features a Jackscrew board mount instead of a latch lock. Other compatible options may exist within the broader Gecko series, but mechanical locking methods and mounting styles must be verified for interchangeability.
