G125-FV11605F3P

Overview

The Harwin G125-FV11605F3P is a 16-position female receptacle connector from the Gecko-SL series. It features a 1.25 mm pitch and two rows of contacts designed for through-hole mounting. The connector supports a voltage rating of 250 V and a current rating of 2 A. Contacts are made of beryllium copper with gold plating, housed in green nylon. It operates within a temperature range of -65°C to +150°C and includes Screw-Lok board mount fixings.

Feature Summary

• Incorporates Screw-Lok threaded jack screws for secure mechanical retention during mating.
• Features polarized keying to ensure correct alignment and prevent misinsertion.
• Utilizes spring-lock technology for reliable contact retention and vibration resistance.

Applications

• Industrial control systems requiring robust board-to-wire connections
• Automotive electronics applications with high vibration exposure
• Consumer appliances needing reliable power distribution

Procurement Notes

Verify that the specific order matches the Gecko-SL series designation and the F3P suffix indicating the through-hole variant with Screw-Lok fixings. Confirm the housing color is green and the contact material is beryllium copper with gold plating. Ensure the procurement documentation specifies the 1.25 mm pitch and 16-position configuration to avoid confusion with similar Gecko series components.

Selection Notes

Select this component when a secure, vibration-resistant connection is required for board-to-wire applications. The Screw-Lok feature provides superior retention compared to standard snap-fit connectors. Consider the 2 A current rating and 250 V voltage limit for circuit design compatibility. The through-hole mounting style suits PCBs where surface mount space is limited or higher mechanical strength is needed.

Part Context

This part belongs to the Harwin Gecko-SL family, which emphasizes high reliability in demanding environments. The series is characterized by its spring-lock mechanism and screw-fixing options. The G125 prefix denotes the 1.25 mm pitch, while the FV indicates a female socket configuration. This specific model is a straight, double-row receptacle designed for durable performance.

Replacement Considerations

Compatible mating headers include G125-MH11605M4R and other Gecko-SL male pins with matching 1.25 mm pitch. Ensure replacement parts maintain the same Screw-Lok fixing style if mechanical retention is critical. Verify that substitute components share the same current and voltage ratings to maintain circuit integrity.
