Overview
The G125-MV12605L0P is a Gecko-Latch series power-to-board header manufactured by Harwin. It features a male pin configuration with 26 positions arranged in a dual-row layout. The connector utilizes a 1.25 mm pitch and is designed for vertical through-hole solder termination. Key electrical ratings include a current capacity of 2 A and voltage ratings of 250 V or 450 V. The housing is constructed from thermoplastic material, while contacts are made of phosphor bronze with gold plating. It operates within a temperature range of -65°C to +150°C.
Feature Summary
- Vertical through-hole mounting design for direct board integration
- Gold-plated phosphor bronze contacts ensuring reliable conductivity
- Thermoplastic housing providing structural stability and insulation
Applications
- Power distribution in industrial control systems
- Signal interconnection in automotive electronics
- Board-to-board connectivity in consumer appliances
Procurement Notes
Verify the specific datasheet version for the G125-MV12605L0P to confirm exact voltage ratings (250 V vs 450 V) as listed in official Harwin documentation. Ensure compatibility with mating sockets from the same Gecko-Latch family. Check for RoHS compliance status and REACH SVHC declarations prior to final procurement approval.
Selection Notes
Select this component when a vertical, high-density power connection is required. The 1.25 mm pitch allows for compact layouts compared to larger pitch alternatives. Verify that the 2 A current rating meets the circuit requirements. Ensure the through-hole footprint matches the PCB design constraints and that the operating temperature range suits the application environment.
Part Context
This part belongs to the Harwin Gecko-Latch series, which focuses on secure, high-reliability connections. The G125 prefix indicates the 1.25 mm pitch family. As a male header, it is designed to mate with corresponding female sockets, forming a complete power or signal interface solution within the broader Gecko ecosystem.
Replacement Considerations
Direct substitutes must maintain the 1.25 mm pitch, 26-position count, and vertical through-hole form factor. Cross-reference with other Harwin G125 series headers if availability is an issue. Ensure any alternative matches the contact material and plating specifications for equivalent performance.
FAQ
What is the contact material for this connector?
