Overview
The Harwin G125-MV11205M2P is a Gecko-SL series power-to-board header featuring 12 positions in a two-row configuration. It utilizes male pin contacts with a 1.25 mm pitch and through-hole solder termination. Rated for 2 A current and 250 V voltage, the connector operates within a temperature range of -65°C to +150°C. The housing is constructed from green nylon, while beryllium copper contacts are gold-plated. This straight-mount component provides reliable electrical interconnection for compact electronic assemblies.
Feature Summary
- Gecko-SL series design optimized for high-density power distribution applications
- Gold-plated beryllium copper contacts ensure stable signal integrity and corrosion resistance
- Nylon housing provides thermal stability and mechanical durability up to 150°C
Applications
- Power distribution in compact electronic assemblies
- Board-to-board interconnections requiring high density
- Industrial control systems with space constraints
Procurement Notes
Verify that the specific part number matches the required 12-position, two-row configuration and through-hole mounting style. Confirm that the 250 V rating and 2 A current capacity align with the system's electrical requirements. Ensure compatibility with the corresponding female socket connectors within the Gecko-SL family for proper mating.
Selection Notes
Select this component when a vertical, through-hole power header is required for dense layouts. The 1.25 mm pitch allows for significant pin count in a small footprint. Consider the beryllium copper contact material for superior spring properties compared to phosphor bronze alternatives in similar form factors.
Part Context
This connector belongs to the Harwin Gecko-SL product line, which focuses on slim-profile solutions for modern electronics. The G125 prefix indicates the 1.25 mm pitch standard. As a male header, it is designed to mate with compatible female sockets or cable assemblies within the same series ecosystem.
Replacement Considerations
Compatible substitutes include other Harwin Gecko-SL headers with identical 12-position, two-row, through-hole specifications. Verify that any alternative maintains the 1.25 mm pitch and matching housing dimensions for interchangeability.
