G125-MH10805M4-1AD1ADP

Overview

The Harwin G125-MH10805M4-1AD1ADP is a Gecko-SL series male pin header designed for wire-to-board connections. It features a 1.25 mm pitch with 10 positions arranged in two rows. The connector utilizes right-angle through-hole solder termination and includes a jackscrew locking mechanism for secure mating. Constructed with phosphor bronze contacts gold-plated for conductivity, the housing is green polyamide rated UL 94 V-0. It supports a current rating of 2 A per contact and operates within a temperature range of -65°C to +150°C.

Feature Summary

• Features a patented four-finger copper alloy contact design for high reliability under extreme vibration conditions.
• Incorporates a jackscrew board mount system to ensure secure mechanical retention during operation.
• Offers a compact low-profile form factor that provides significant space savings compared to larger pitch connectors.

Applications

• High-reliability electronic product designs requiring miniature packaging
• Applications subject to extreme vibration environments
• Wire-to-board interconnections in demanding industrial settings

Procurement Notes

Verify the specific ordering suffix to confirm the exact configuration, including pin count, row arrangement, and locking mechanism type. Ensure compatibility with mating sockets from the same Gecko-SL family. Confirm RoHS compliance status and flammability ratings against project requirements before finalizing procurement decisions.

Selection Notes

Select this component when a right-angle through-hole male header is required for dense PCB layouts. The 1.25 mm pitch allows for higher density than standard headers. Consider the jackscrew feature if vibration resistance is critical. Verify that the 2 A current rating meets the electrical load requirements of the target circuit application.

Part Context

This part belongs to the Harwin Gecko-SL family, which focuses on high-performance connectivity in small spaces. The G125 series is engineered for durability in harsh environments, utilizing specialized contact materials and robust housing compounds. It serves as a reliable solution for modern electronics where size constraints and operational stability are paramount.

Replacement Considerations

Direct substitutes must match the 1.25 mm pitch, 10-position dual-row configuration, and right-angle through-hole mounting style. Verify that alternative components support the same 2 A current rating and -65°C to +150°C operating temperature range. Ensure compatible locking mechanisms are present if vibration resistance is required.
