G125-FV11605F2P

Overview

The G125-FV11605F2P is a 16-position, dual-row female PCB receptacle from the Harwin Gecko-SL series. It features a 1.25 mm (0.049 inch) contact pitch and utilizes gold-plated beryllium copper contacts for reliable signal transmission. Designed for through-hole mounting with a reverse fix mechanism, the connector supports a rated current of 2 A per contact and withstands voltages up to 450 V. The housing is constructed from green polyamide (PA4T) with UL 94 V-0 flammability rating. Operating temperatures range from -65°C to +150°C, ensuring stability in demanding environments.

Feature Summary

• Reverse Fix mechanical locking system ensures secure board attachment
• Gold-plated contacts provide high reliability and corrosion resistance
• Low profile dual-row design facilitates stacking and cable mating

Applications

• High-reliability signal interconnects in industrial equipment
• Stacked circuit board assemblies requiring secure retention
• Cable-to-board connections in compact electronic modules

Procurement Notes

Verify that the specific suffix '2P' corresponds to the Reverse Fix variant rather than standard vertical or right-angle configurations. Confirm the insulation material is PA4T if halogen-free requirements are strict. Ensure the procurement documentation explicitly states the 450 V rating, as some generic listings may cite lower values. Cross-reference the RoHS status with the latest manufacturer declaration to ensure compliance with current environmental regulations.

Selection Notes

Select this component when a secure, non-vibrating connection is required without additional screws. The 1.25 mm pitch offers a balance between density and ease of assembly compared to finer pitches. Consider the 2 A current rating for signal lines; do not use for high-power applications exceeding this limit unless derating is applied. The reverse fix feature distinguishes it from standard G125 headers, making it suitable for applications where accidental disconnection must be prevented.

Part Context

This part belongs to the Harwin Gecko-SL (Screw-Lok) family, which emphasizes mechanical security in micro-miniature connectors. Unlike standard Gecko headers, the SL series incorporates a unique reverse-fix housing design that locks into the PCB. This series is engineered for harsh environments, offering durability and consistent performance across a wide temperature range, serving as a robust alternative to traditional screw-lock connectors in space-constrained designs.

Replacement Considerations

Direct substitutes within the same series include G125-FV11605F1P for standard vertical orientation without reverse fix. For different pin counts, refer to G125-FV1XX05F2P variants. No cross-brand direct replacements exist due to the proprietary reverse-fix mechanism; alternative solutions require redesigning the PCB footprint and mechanical constraints.
