G125-FS11005F1R

Overview

The Harwin G125-FS11005F1R is a Gecko-SL series power-to-board connector designed for vertical surface-mount technology (SMT) applications. It features a dual-row configuration with five positions per row, totaling ten contact points. The component utilizes a 1.25 mm pitch and incorporates a jackscrew locking mechanism to ensure secure mating stability. Rated for 2 A current and up to 450 V voltage, it operates within a temperature range of -65°C to +150°C. The housing is constructed from polyamide (PA), while contacts are gold-plated copper alloy.

Feature Summary

• Vertical SMT mounting style optimized for automated pick-and-place assembly processes.
• Integrated jackscrew locking system provides positive mechanical retention during operation.
• Dual-row socket design facilitates high-density power distribution on PCBs.

Applications

• Industrial control systems requiring robust board-to-board connections
• Telecommunications infrastructure equipment
• Automotive electronics modules

Procurement Notes

Verify the specific ordering suffix against official Harwin documentation to confirm the presence of the jackscrew locking feature and surface-mount termination type. Ensure compatibility with standard reflow soldering profiles and check for RoHS compliance status prior to integration into production lines.

Selection Notes

Select this component when vertical orientation and secure mechanical locking are required for power delivery. The 1.25 mm pitch allows for compact layouts compared to larger connectors. Confirm that the PCB footprint matches the specified SMT pad dimensions and that the jackscrew clearance does not interfere with adjacent components.

Part Context

This part belongs to the Gecko-SL family, which emphasizes secure locking mechanisms for vibration-prone environments. The FS designation indicates a female socket variant intended for vertical surface-mount installation. It complements male headers and cable assemblies within the same 1.25 mm pitch ecosystem.

Replacement Considerations

Direct substitutes include other Harwin Gecko-SL vertical SMT female connectors with identical 10-position configurations and jackscrew locking features. Cross-referencing datasheets is essential to verify matching pitch, current ratings, and mechanical locking types before substitution.

FAQ

What type of locking mechanism does the G125-FS11005F1R use?

It utilizes a jackscrew locking mechanism to ensure secure mating between the header and socket.

Is this connector suitable for high-temperature environments?

Yes, it is rated for operation up to +150°C, making it suitable for demanding thermal conditions.
