Overview
The G125-MS11005M1R is a Gecko-SL series power-to-board connector from Harwin Inc. It features a 1.25 mm pitch, 2-row configuration with 10 positions (5+5). Designed for surface mount technology (SMT), it utilizes male pin contacts made of phosphor bronze with gold plating. The unit operates within a temperature range of -65°C to +150°C and supports current ratings up to 2 A at voltages of 250 V or 450 V. The housing is constructed from polyamide (PA) with UL 94 V-0 flammability rating.
Feature Summary
- Gecko-Latch locking mechanism ensures secure mating stability
- Surface mount design facilitates automated pick-and-place assembly
- Gold-plated phosphor bronze contacts provide reliable conductivity
Applications
- Power distribution in compact electronic modules
- Server and storage backplane interconnects
- Industrial control system board-to-board connections
Procurement Notes
Verify the specific suffix 'M1R' against official Harwin documentation to confirm tape and reel packaging specifications. Ensure compatibility with SMT reflow profiles and check for RoHS compliance status via the manufacturer's latest datasheet before finalizing procurement orders.
Selection Notes
Select this component when high-density power delivery is required in space-constrained designs. The 1.25 mm pitch allows for significant current capacity relative to footprint size. Consider the vertical orientation and latch feature for applications requiring robust mechanical retention during vibration.
Part Context
This part belongs to the Harwin Gecko-SL family, engineered for demanding power applications. The series combines small form factor with high reliability, utilizing a unique latching system. It serves as a male header solution for mating with corresponding female sockets in power-to-board architectures.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Cross-referencing requires matching pitch, row count, and mounting style with equivalent Gecko-series variants or other 1.25 mm SMT headers.
