G125-MH11605L7P

Overview

The Harwin G125-MH11605L7P is a male pin header from the Gecko-Latch series, featuring a 1.25 mm pitch and 16 contacts arranged in a dual-row configuration. It utilizes right-angle through-hole mounting with gold-plated phosphor bronze contacts. The connector supports a current rating of 2 A and a voltage rating of 250 V, operating within a temperature range of -65°C to +150°C. Constructed with green polyamide insulation rated UL 94 V-0, it incorporates a jackscrew locking mechanism for secure board-to-board or wire-to-board interconnections.

Feature Summary

• Incorporates a jackscrew locking mechanism for secure mechanical retention
• Provides low-profile dual-row interconnect solution
• Features gold-plated phosphor bronze contacts for reliable conductivity
• Utilizes UL 94 V-0 rated green polyamide insulation

Applications

• Board-to-board interconnections requiring secure latching
• Wire-to-board connections in compact electronic assemblies
• Industrial control systems needing vibration-resistant connectors
• Consumer electronics with space-constrained layouts

Procurement Notes

Verify the specific suffix L7P confirms the right-angle through-hole variant with jackscrew locking. Ensure compatibility with mating sockets from the same Gecko-Latch family. Confirm that the 3.3 mm tail length meets PCB thickness requirements. Check for RoHS compliance documentation if required by project specifications. Validate that the 2 A current rating suffices for the intended circuit load.

Selection Notes

Select this component when a secure, latching connection is critical for dual-row applications. The right-angle design facilitates horizontal cabling or board stacking. The jackscrew feature distinguishes it from standard push-pull connectors, offering enhanced retention. Consider the 1.25 mm pitch for dense pin counts in limited spaces. Ensure the through-hole mounting style aligns with the target PCB manufacturing capabilities.

Part Context

This part belongs to Harwin's Gecko-Latch series, designed for high-reliability interconnects. The series emphasizes secure locking mechanisms to prevent accidental disconnection. The G125 prefix indicates the 1.25 mm pitch family. The MH suffix typically denotes male headers, while L7P specifies the right-angle through-hole configuration with locking features.

Replacement Considerations

• G125-MH11605M4R (Right-angle THT, but lacks jackscrew locking)
• G125-MS11605L3P (Straight SMT variant, different mounting style)

FAQ
