Overview
The G125-FV11205F3P is a 12-position female socket connector from the Gecko SL Reverse Fix series by Harwin Inc. It features a 1.25mm (0.049 inch) pitch and is designed for through-hole mounting with solder termination. The connector utilizes gold-plated phosphor bronze contacts housed in green polyamide insulation rated UL94 V-0. It supports a current rating of 2A and voltage up to 450VAC/DC, operating within a temperature range of -65°C to +150°C.
Feature Summary
- Reverse fix design with jackscrew locking mechanism for secure board attachment
- Gold-plated contacts ensure reliable signal transmission
- High-temperature resistant polyamide insulation material
Applications
- Board-to-board interconnections requiring reverse fixation
- Signal processing modules in industrial equipment
- Consumer electronics assemblies needing compact high-density connections
Procurement Notes
Verify the specific ordering suffix to confirm pin count, orientation, and packaging details against the official Harwin datasheet. Ensure compatibility with mating connectors in the same Gecko SL series. Confirm RoHS compliance status if required for your application standards before finalizing procurement orders.
Selection Notes
Select this component when a 12-position through-hole female connector with reverse fix capability is needed. Consider the 1.25mm pitch constraint and the requirement for jackscrew locking. Evaluate thermal requirements against the 150°C maximum operating limit and ensure PCB layout accommodates the specific stacking heights associated with this reverse fix configuration.
Part Context
This part belongs to the Harwin Gecko SL family, which specializes in micro-miniature connectors with a 1.25mm pitch. The 'FV' designation indicates a female socket with reverse fix features, distinguishing it from standard headers or cable assemblies within the broader G125 product line. It is engineered for high-reliability applications in space-constrained environments.
Replacement Considerations
Direct substitutes include other 12-position 1.25mm pitch female connectors with reverse fix mechanisms from compatible manufacturers. Verify mechanical dimensions, locking method, and electrical ratings match exactly. Cross-reference with Harwin's own variants like G125-FV11205F2P for packaging differences.
