Overview
The G125-MV15005M1R is a Gecko-SL series male plug connector manufactured by Harwin Inc. It features a 1.25mm (0.049 inch) pitch with 50 positions arranged in a double row (2x25). Designed for vertical through-board mounting, it utilizes screw-locking mechanisms for secure attachment. The contacts are gold-plated beryllium copper, rated for 2A current and 450V voltage. Operating temperature ranges from -65°C to +150°C.
Feature Summary
- Screw-Lok locking mechanism ensures reliable connection stability
- Gold-plated contacts provide corrosion resistance and low contact resistance
- Vertical through-board termination supports automated assembly processes
Applications
- Industrial control systems requiring high-reliability interconnects
- Power distribution boards in automotive applications
- Test and measurement equipment interfaces
Procurement Notes
Verify the specific ordering suffix matches the required pin count and termination style. Confirm that the Screw-Lok feature is necessary for the mechanical design. Ensure compatibility with mating female connectors within the same Gecko-SL family. Check RoHS compliance status if required by project specifications.
Selection Notes
Select this component when vertical orientation and screw-locking security are critical. The 1.25mm pitch allows for dense circuit board layouts. Gold plating is suitable for environments requiring long-term reliability. Consider the 3mm PCB termination length for board thickness constraints.
Part Context
This part belongs to the Harwin Gecko-SL family, designed for demanding industrial and automotive environments. The series offers various configurations including headers, receptacles, and cable assemblies. The G125-MV15005M1R specifically addresses needs for robust power-to-board connections with secure locking.
Replacement Considerations
Direct substitutes include other Harwin Gecko-SL male plugs with identical 50-position, 1.25mm pitch, and Screw-Lok features. Verify mechanical dimensions and electrical ratings before substitution. Cross-model generic features do not guarantee interchangeability.
