G125-MH11205L7R

Overview

The G125-MH11205L7R is a male header from the Harwin Gecko-SL series, featuring a 1.25 mm pitch and 20 positions in a dual-row configuration. It utilizes right-angle through-hole solder pin termination for board mounting. The connector employs gold-plated phosphor bronze contacts rated for 2 A current and includes jackscrew locking mechanisms. Designed for high reliability, it operates within a temperature range of -65 °C to +150 °C and meets UL 94 V-0 flammability standards.

Feature Summary

• Patented four-finger copper alloy contact design ensures high performance under extreme vibration conditions.
• Jackscrew locking mechanism provides secure mating retention between header and housing.
• Low-profile miniature package offers significant space savings compared to standard high-performance connectors.

Applications

• High-reliability electronic product designs requiring robust interconnects
• Applications subject to extreme vibration environments
• Space-constrained systems demanding high-density connections

Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number with official datasheets. Confirm that the specific ordering suffix matches the required termination style and packaging format. Ensure compliance with RoHS directives and check for any relevant REACH SVHC declarations prior to integration into production assemblies.

Selection Notes

Select this component when a shrouded male header with right-angle through-hole termination is required. The 1.25 mm pitch supports high-density layouts while maintaining a 2 A current rating per contact. Verify that the jack-screw locking feature aligns with the mechanical constraints of the target application environment.

Part Context

This component belongs to the Harwin Gecko-SL family, engineered for demanding industrial and commercial applications.
