Overview
The Harwin G125-MH11605M4P is a Gecko-SL series male plug connector featuring a 1.25 mm pitch and 16 positions arranged in two rows. It utilizes right-angle through-hole solder pin termination with gold-plated phosphor bronze contacts rated for 2 A. The polyamide housing provides UL 94 V-0 flammability rating, operating between -65°C and +150°C. This component incorporates Jackscrew board mount locking mechanisms and is supplied in tape-and-reel packaging.
Feature Summary
- Jackscrew locking mechanism for secure board mounting
- Right-angle through-hole solder termination
- Gold-plated phosphor bronze contacts
- Polyamide insulation with UL 94 V-0 rating
Applications
- High-density power distribution on PCBs
- Industrial control system interconnects
- Automotive electronics modules
- Telecommunications equipment backplanes
Procurement Notes
Verify the specific ordering suffix against the official Harwin datasheet to confirm exact contact plating thickness, housing color, and reel quantity specifications. Ensure compatibility with mating female sockets within the same Gecko-SL family. Confirm RoHS compliance status and lead times directly with authorized distributors prior to procurement planning.
Selection Notes
Select this part for applications requiring robust mechanical retention via jackscrews rather than standard latches. The right-angle form factor aids in space-constrained layouts. Verify that the 2 A current rating per contact aligns with circuit requirements. Ensure the 1.25 mm row spacing matches the target PCB footprint design rules.
Part Context
This component belongs to the Harwin Gecko-SL product line, designed for high-reliability interconnect solutions. The series emphasizes secure locking mechanisms and compact density. It serves as a male header counterpart to various female socket options within the broader Gecko ecosystem, facilitating standardized board-to-board connections.
Replacement Considerations
Direct substitutes include other Harwin Gecko-SL male headers with identical 1.25 mm pitch, 16-position count, and right-angle through-hole configuration. Verify matching jackscrew locking features and contact material specifications before substitution.
