Overview
The Harwin G125-MH116M3-04AD000P is a Gecko-MT series power-to-board header featuring 16+4 positions with a 1.25 mm pitch. It utilizes a horizontal orientation and Screw-Lok board mount mechanism for secure attachment. The connector supports a current rating of 2 A and operates within a temperature range of -65°C to +150°C. Constructed with phosphor bronze contacts, gold plating, and green polyamide housing, it meets UL 94 V-0 flammability standards.
Feature Summary
- Horizontal PCB backshell kit configuration designed for power and signal integration
- Screw-Lok board mount system provides robust mechanical fixation
- Jackscrew locking mechanism ensures reliable mating stability
Applications
- Power distribution modules requiring horizontal mounting
- Signal processing interfaces in compact electronic assemblies
- Industrial equipment needing secure board-mounted connections
Procurement Notes
Verify the specific Gecko-MT variant designation against official Harwin documentation to ensure compatibility with intended mating connectors. Confirm that the horizontal orientation and Screw-Lok mounting style align with the mechanical constraints of the target PCB layout. Check for any recent product change notifications regarding material specifications or packaging formats before finalizing procurement orders.
Selection Notes
Select this component when a horizontal power-to-board interface is required with high mechanical retention. The 1.25 mm pitch allows for dense pinout arrangements suitable for mixed power and signal applications. Ensure the design accommodates the specific height and footprint requirements of the Screw-Lok mounting hardware and the associated mating cable assembly.
Part Context
This part belongs to the Harwin Gecko-MT family, which specializes in power-to-board solutions. The series emphasizes secure mounting and high reliability for demanding environments. The Gecko-MT line differentiates itself through specialized mounting features like Screw-Lok, catering to applications where vibration resistance and stable electrical contact are critical priorities.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Direct replacement requires matching the exact Gecko-MT series specifications, including the 16+4 position count, 1.25 mm pitch, and horizontal Screw-Lok mounting configuration.
