Overview
The G125-MH11205L3P is a Gecko-Latch series header connector manufactured by Harwin. It features a 1.25 mm pitch and a 2x6 position configuration, totaling 12 contacts. The component utilizes male pin contacts with gold plating for reliable signal transmission. Designed for through-hole mounting, it offers a right-angle orientation for efficient PCB layout. The housing is constructed from green polyamide material rated UL94 V-0 for flammability. Electrical specifications include a voltage rating of 250V and a current rating of 2A. The operating temperature range spans from -65°C to 150°C.
Feature Summary
- Right-angle through-hole mounting design for space-efficient board integration
- Gold-plated male pin contacts ensuring durable electrical connectivity
- UL94 V-0 rated polyamide insulation for enhanced fire safety
Applications
- Industrial control systems requiring high-reliability interconnects
- Consumer electronics with compact form factor constraints
- Automotive electronic modules needing robust thermal performance
Procurement Notes
Verify the specific suffix codes against official Harwin documentation to confirm exact contact count and orientation. Ensure compatibility with mating sockets within the Gecko-Latch family. Confirm RoHS compliance status via the manufacturer's latest datasheet before finalizing procurement orders.
Selection Notes
Select this part when a right-angle, 12-position header is required for through-hole assembly. The 1.25 mm pitch suits dense circuit designs. Verify that the 2A current rating meets system requirements. Consider the right-angle profile for vertical clearance limitations on the printed circuit board.
Part Context
This component belongs to the Harwin Gecko-Latch series, known for high-reliability connections in demanding environments. The G125 series provides various pitch options and configurations. This specific model represents a standard right-angle plug variant within the broader connector ecosystem.
Replacement Considerations
Direct substitutes are limited due to unique latch mechanisms. Compatible alternatives must match the 1.25 mm pitch, 2x6 layout, and right-angle THT style. Verify mechanical locking features and mating interface dimensions before substitution.
