G125-MH12605M3P

Overview

The Harwin G125-MH12605M3P is a Gecko-SL series male plug header featuring a 26-position, 2-row 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 1 GOhm insulation resistance. The connector employs a hex socket Screw-Lok reverse fix locking mechanism and operates within a temperature range of -65°C to +150°C. Constructed from green polyamide (PA) housing with UL 94 V-0 flammability rating, this shrouded component ensures secure board-to-board or wire-to-board interconnections in demanding electronic applications.

Feature Summary

• Hex socket Screw-Lok reverse fix locking mechanism for secure retention
• Gold-plated phosphor bronze contacts ensuring reliable signal transmission
• Shrouded design providing protection against misalignment during mating

Applications

• Industrial control systems requiring robust mechanical retention
• Consumer electronics with high-density connection needs
• Automotive embedded modules operating in extreme temperatures

Procurement Notes

Verify the specific suffix M3P corresponds to the Screw-Lok reverse fix variant rather than standard board mount versions. Confirm RoHS compliance status via the manufacturer's declaration before integration. Ensure PCB footprint matches the 1.25 mm pitch and right-angle THT specifications to avoid assembly errors. Cross-reference the official datasheet for precise mechanical dimensions and locking torque requirements.

Selection Notes

Select this model when high-vibration environments necessitate the Screw-Lok locking feature over standard headers. The 26-position capacity suits applications requiring moderate density without excessive board space usage. Consider the right-angle orientation for space-constrained layouts where vertical clearance is limited. Verify that the 2 A current rating aligns with the circuit's electrical load requirements.

Part Context

This component belongs to the Harwin Gecko-SL family, known for compact form factors and versatile locking options. It complements female counterparts like the G125-FV series to create complete interconnect solutions. The series supports various mounting styles and contact counts, offering engineers flexibility in designing dense, reliable electronic assemblies across multiple industries.

Replacement Considerations

No direct public substitute part numbers are confirmed for this specific Screw-Lok variant. Generic 1.25 mm 2x13 pin headers lack the integrated locking mechanism and may not provide equivalent mechanical security. Evaluate compatible Gecko-SL female connectors for mating pairs rather than seeking alternative male headers.
