G125-MH13405M4P

Overview

The G125-MH13405M4P is a Gecko-SL series header connector manufactured by Harwin Inc. It features a 34-position, two-row male pin configuration with a 1.25 mm pitch. Designed for right-angle through-hole mounting, it utilizes gold-plated phosphor bronze contacts rated for 2 A current and 450 V voltage. The housing is constructed from green polyamide (PA4T) with UL 94 V-0 flammability rating. Operating temperatures range from -65°C to +150°C. Key mechanical specifications include a 3.3 mm solder tail length and a jackscrew locking mechanism for secure board attachment.

Feature Summary

• Integrated jackscrew locking system provides secure mechanical fixation between the connector and the printed circuit board.
• Right-angle through-hole design facilitates horizontal board mounting while maintaining vertical wire access.
• Gold-plated phosphor bronze contacts ensure reliable electrical performance and corrosion resistance.

Applications

• Industrial control systems requiring robust board-to-wire connections
• Automotive electronics assemblies demanding high vibration resistance
• Consumer appliance mainboards utilizing screw-lock retention

Procurement Notes

Verify component authenticity against official Harwin documentation before integration. Confirm that the specific ordering suffix matches the required 34-position configuration and right-angle orientation. Ensure compatibility with existing PCB footprint designs and mating cable assemblies within the Gecko-SL ecosystem.

Selection Notes

Select this model when a secure, screw-locked connection is mandatory for high-vibration environments. The right-angle form factor suits space-constrained layouts where vertical headers are impractical. Verify that the 1.25 mm pitch aligns with mating connector standards and that the 2 A rating meets circuit load requirements.

Part Context

This component belongs to the Harwin Gecko-SL family, characterized by its distinctive jackscrew locking feature. The series offers various row counts and mounting styles, but this specific part number denotes a 34-position, right-angle, through-hole variant. It complements other Gecko connectors by providing enhanced mechanical stability compared to standard snap-fit designs.

Replacement Considerations

G125-MH13405M4R serves as a tape-and-reel alternative to the bulk-packaged M4P variant. Both share identical electrical and mechanical specifications, differing only in packaging format. No functional substitutes exist outside the Gecko-SL series due to the unique jackscrew interface geometry.

FAQ

What is the purpose of the jackscrew feature on this connector?

The jackscrew allows for threaded fixation directly into the PCB, preventing accidental disconnection caused by vibration or thermal cycling.

Is this connector compatible with standard Gecko mating cables?

Yes, it is designed to mate with standard Gecko-SL series female connectors and corresponding wire harnesses.
