Overview
The G125-FV116F1-04AB000P is a Gecko-MT series PCB receptacle connector manufactured by Harwin Inc. It features a 1.25 mm pitch and contains 20 positions arranged as 16 signal contacts and 4 power contacts. The connector utilizes a screw lock rear fix mechanism for secure mating. It is designed for through-hole vertical mounting on printed circuit boards. The contact surfaces are finished with gold plating to ensure reliable electrical performance.
Feature Summary
- Screw lock rear fix mechanism ensures secure connection stability
- Gold-plated contacts provide durable electrical conductivity
- Vertical through-hole termination supports direct PCB integration
Applications
- Power distribution in industrial control systems
- Signal transmission in embedded electronics
- Board-to-board interconnects in telecommunications equipment
Procurement Notes
Verify the complete part number including suffixes against official Harwin documentation to confirm specific packaging and termination details. Ensure compatibility with mating header connectors within the Gecko-MT series. Confirm that the through-hole footprint matches the target PCB design specifications before finalizing procurement orders.
Selection Notes
Select this component when a 1.25 mm pitch connector with mixed signal and power capacity is required. The 16+4 contact arrangement suits applications needing dedicated power lines alongside data signals. Consider the screw lock feature if vibration resistance is critical for the installation environment.
Part Context
This part belongs to the Gecko-MT series, which offers high-density interconnect solutions. The series is characterized by its compact form factor and robust mechanical locking systems. It serves as a standard interface for connecting peripheral modules to main processing boards in various electronic assemblies.
Replacement Considerations
Direct substitutes must match the 1.25 mm pitch, 20-position layout, and screw lock mechanism. Verify pinout configurations and current ratings of alternative parts. Cross-reference with Harwin's official replacement guides to ensure functional equivalence.
