G125-FS11205F2R

Overview

The Harwin G125-FS11205F2R is a high-reliability surface mount receptacle from the Gecko series. It features 12 positions arranged in two rows with a 1.25mm (0.049 inch) mating pitch. The connector utilizes gold-plated contacts and a green polyamide insulation body rated UL94 V-0. Designed for board-to-board or cable applications, it supports pick-and-place assembly via tape and reel packaging. The unit operates within a temperature range of -65°C to 150°C and includes polarizing keying features.

Feature Summary

• Patented four-finger contact design ensures stable electrical connection under high vibration and shock conditions
• Integrated latching mechanism provides secure mechanical retention during operation
• Polarized keying prevents incorrect mating orientation between components

Applications

• Automotive electronics systems
• General industrial equipment
• High-reliability signal interconnects

Procurement Notes

Verify the specific suffix 'F2' confirms the intended contact configuration and plating thickness against official datasheets. Ensure the 'R' suffix matches required tape and reel specifications for automated assembly lines. Cross-reference the full part number with manufacturer documentation to confirm current availability status and lead times before finalizing procurement plans.

Selection Notes

Select this component when high vibration resistance is critical for signal integrity. The surface mount profile suits compact PCB layouts requiring robust mechanical locking. Verify that the 1.25mm pitch aligns with mating header dimensions and that the operating temperature range meets environmental requirements for the target application zone.
