G125-MV11205M1P

Overview

The Harwin G125-MV11205M1P is a Gecko-SL series power-to-board header featuring a 1.25 mm pitch and 12 positions in a dual-row configuration. It utilizes male pin contacts with gold plating on beryllium copper, rated for 2 A current. Designed for through-hole mounting at a straight angle, the connector employs a reverse fix mechanism for secure PCB attachment. The housing is constructed from green nylon, supporting an operating temperature range of -65°C to +150°C.

Feature Summary

• Reverse fix mechanism ensures secure mechanical retention within the printed circuit board assembly.
• Gold-plated beryllium copper contacts provide reliable electrical conductivity and corrosion resistance.
• Shrouded design protects mating connections and prevents misalignment during stacking or cable insertion.

Applications

• Power distribution in compact electronic modules
• Stacked board interconnects in dense assemblies
• Cable mating interfaces requiring secure retention

Procurement Notes

Verify that the specific Gecko-SL variant matches the required reverse fix orientation and vertical profile. Confirm that the 1.25 mm pitch and 2x6 layout align with the target PCB footprint. Ensure compatibility with the intended mating socket or cable assembly before finalizing procurement orders.

Selection Notes

Select this component when a low-profile, high-reliability power connection is needed in space-constrained environments. The reverse fix feature distinguishes it from standard headers by offering enhanced mechanical stability. Consider the 2 A rating and thermal limits when designing for continuous load conditions.

Part Context

This part belongs to the Harwin Gecko-SL family, which specializes in screw-lock style connectors for robust industrial applications. The series offers various configurations including cable assemblies and housings, all sharing the consistent 1.25 mm pitch and durable construction standards typical of the brand's power-to-board solutions.

Replacement Considerations

No direct substitute part numbers are publicly confirmed for this specific reverse-fix configuration. Alternative selection requires matching the 1.25 mm pitch, 12-position dual-row layout, and through-hole mounting style while verifying mechanical retention methods.
