Overview
The G125-MV11205L0R is a Gecko-Latch series power-to-board connector manufactured by Harwin. It features a vertical surface mount design with a 1.25 mm pitch and 12 positions arranged in a 2x6 configuration. The component utilizes phosphor bronze contacts with gold plating for reliable conductivity. Rated for 2 A current and 250 V/450 V voltage, it operates within a temperature range of -65 °C to +150 °C. The housing is constructed from polyamide (PA), providing high insulation resistance of 10 GOhms. This header is designed for direct soldering to printed circuit boards.
Feature Summary
- Vertical surface mount mounting style for compact board integration
- Gecko-Latch mechanism ensures secure mating retention
- Gold-plated phosphor bronze contacts for corrosion resistance
- Polyamide housing material supports high-temperature operation
Applications
- Industrial control systems requiring robust power connections
- Automotive electronics modules
- Consumer appliance mainboards
- Telecommunications infrastructure equipment
Procurement Notes
Verify the specific ordering suffix against the official Harwin datasheet to confirm orientation and packaging details. Ensure compatibility with the corresponding female counterpart from the same Gecko-Latch family. Confirm RoHS compliance status through the manufacturer's latest documentation before finalizing procurement orders.
Selection Notes
Select this component when a vertical, low-profile power connection is required on dense PCB layouts. The 1.25 mm pitch allows for higher density compared to standard headers. Consider the thermal rating of the polyamide housing if operating near the upper temperature limit. Ensure the mating connector matches the latch mechanism type for proper mechanical engagement.
Part Context
This part belongs to the Harwin Gecko-Latch series, designed for high-reliability power applications. The series offers various configurations including vertical and right-angle options. The G125 prefix indicates the 1.25 mm pitch family. This specific model provides a male header solution for connecting power sources to board-level circuits securely.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Direct replacement requires matching the 1.25 mm pitch, 12-position count, vertical orientation, and Gecko-Latch interface specifications exactly.
