G125-MV11005M1P

Overview

The Harwin G125-MV11005M1P is a Gecko-SL series vertical through-board connector featuring a 1.25 mm pitch and 10 positions in a dual-in-line configuration. It utilizes gold-plated phosphor bronze contacts housed in polyamide insulation, rated for 250 V and 2 A current. The component supports a temperature range of -65°C to +150°C and incorporates screw-fixing board mount studs for secure attachment.

Feature Summary

• Integrates jack-screw locking mechanism for reliable board mounting
• Features gold-plated phosphor bronze contacts for corrosion resistance
• Designed with polyamide housing for UL 94 V-0 flammability rating

Applications

• Industrial control systems requiring secure power connections
• Automotive electronics assemblies needing vibration resistance
• Consumer appliance mainboard interconnects

Procurement Notes

Verify the specific suffix 'M1P' against official Harwin documentation to confirm the presence of pick-and-place tape and reel packaging versus bulk packing. Ensure compatibility with mating sockets in the same Gecko-SL family. Confirm that the screw-fixing feature aligns with the target PCB mechanical design constraints before finalizing procurement orders.

Selection Notes

Select this part when a robust, vertically mounted header with integrated mechanical locking is required. The 1.25 mm pitch suits dense layouts while the screw-fixing option provides superior stability compared to standard press-fit headers. Consider the 2 A current rating for power distribution applications within the specified thermal limits.

Part Context

This component belongs to the Harwin Gecko-SL family, which emphasizes high-reliability interconnect solutions. The series combines standard rectangular connector functionality with unique mechanical locking features, distinguishing it from generic pin headers by offering enhanced retention forces suitable for harsh environments.

Replacement Considerations

Direct substitutes include other Harwin Gecko-SL variants with matching 1.25 mm pitch and 10-position count, such as G125-MV11005M2R, provided the packaging and locking mechanism requirements are identical. Cross-brand replacements require careful verification of pin spacing, housing dimensions, and locking interface geometry.
