Overview
The G125-FV104F3-04AB000P is an 8-position (4+4 power) PCB receptacle from Harwin’s Gecko-MT series. It features a 1.25 mm pitch and utilizes a through-hole straight mounting configuration. The connector employs a screw-lock mechanism for secure cable attachment and includes a mating flange with polarizing keys to ensure correct alignment. Constructed with polyamide insulation, it supports a current rating of 2A per signal contact and 10A per power contact.
Feature Summary
- Screw-lock rear panel mount design for secure cable retention
- Integrated polarizing keys prevent incorrect mating orientation
- Through-hole straight termination ensures stable PCB connection
Applications
- Industrial control system interconnections
- Power distribution modules requiring high current capacity
- Board-to-cable connections in compact electronic enclosures
Procurement Notes
Verify the specific ordering suffix against the official Harwin datasheet to confirm pinout, plating, and mechanical variations. Ensure the selected variant matches the required current rating and insulation material specifications for the intended operating environment. Cross-reference the part number with authorized distributors to confirm availability and authenticity before procurement.
Selection Notes
Select this component when a robust, high-current board-to-cable interface is required within a limited footprint. The 1.25 mm pitch allows for dense packing while maintaining adequate spacing for power lines. Consider the screw-lock feature if vibration resistance is critical. Verify that the through-hole mounting style aligns with the PCB manufacturing capabilities and thermal requirements.
Part Context
This receptacle belongs to the Gecko-MT series, designed for applications demanding reliable power transmission in space-constrained environments. The series emphasizes durability and ease of assembly through its screw-lock mechanism. This specific model integrates both signal and power contacts, offering a consolidated solution for mixed-signal applications without requiring multiple connector types.
Replacement Considerations
No public confirmed substitute part numbers are available for this specific configuration. Direct replacement requires matching the 1.25 mm pitch, 8-position layout, and screw-lock mechanical interface. Verify compatibility with existing mating cables and PCB footprints before considering alternative connectors.
