Overview
The Harwin G125-MS12605M1R is a Power to the Board connector from the Gecko-SL series. It features a male pin header configuration with a 1.25 mm pitch and 26 positions arranged in two rows. Designed for surface mount (SMD/SMT) installation, it utilizes solder termination. The contacts are made of phosphor bronze with gold plating, housed in green polyamide (PA). Rated for 2 A current and 250 V/450 V voltage, it operates between -65°C and +150°C with an insulation resistance of 10 GOhms.
Feature Summary
- Patented four-finger contact design ensures reliable electrical connection under high vibration and shock conditions.
- Vertical surface mount construction facilitates automated pick-and-place assembly processes.
- High-temperature polyamide housing supports operation up to +150°C.
Applications
- Industrial control systems requiring high-reliability interconnects
- Automotive electronics subject to mechanical stress
- Consumer devices needing compact power distribution
Procurement Notes
Verify the specific ordering suffix against the official datasheet to confirm pin count and mounting style. Ensure compatibility with standard SMT reflow profiles. Confirm RoHS compliance status through manufacturer documentation prior to integration.
Selection Notes
Select this component for applications demanding robust performance in harsh environments. The 1.25 mm pitch allows for dense board layouts. Verify that the 2 A per contact rating meets circuit requirements. Consider the straight vertical profile for board-to-board or cable-to-board connections.
Part Context
This part belongs to the Harwin Gecko-SL family, designed for high-reliability power and signal transmission. The series is characterized by its patented contact technology and compact form factor, suitable for space-constrained electronic assemblies requiring durable connections.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Cross-reference with other Harwin Gecko-SL variants if pin count or orientation differs.
