Overview
The Harwin G125-MS11605L3P is a male dual in-line vertical surface mount connector from the Gecko series. It features a 1.25 mm pitch with 16 contacts arranged in two rows. The connector supports 250 V voltage and 2.8 A current ratings. Constructed with phosphor bronze contacts gold-plated for conductivity, it utilizes a nylon housing. Operating temperatures range from -65°C to 150°C. The design includes a 3 mm tail pin length for secure soldering.
Feature Summary
- Provides a low-profile interconnect solution suitable for board-to-board and wire-to-board applications.
- Features a latching mechanism designed for secure connection stability.
- Vertical surface mount orientation facilitates compact PCB integration.
Applications
- Power to the Board interconnects
- Board-to-board signal transmission
- Wire-to-board connections
Procurement Notes
Verify the specific part number against official Harwin documentation to confirm contact count, pitch, and mounting style. Ensure compatibility with mating connectors within the Gecko series. Check for any legislative compliance documents available on the manufacturer's website. Confirm surface mount requirements and soldering parameters prior to implementation.
Selection Notes
Select this component when a low-profile, high-density connection is required for power or signal lines. The 1.25 mm pitch allows for significant I/O density in limited space. Consider the vertical orientation and surface mount technology for automated assembly processes. Verify that the 2.8 A current rating meets the circuit requirements.
Part Context
This component belongs to the Harwin Gecko series, which specializes in latching connectors. The G125 designation indicates the 1.25 mm pitch variant. The MS suffix typically denotes male surface mount configuration. This series is engineered for robust performance in demanding electronic environments.
Replacement Considerations
Consult official Harwin documentation for verified substitute part numbers within the Gecko family. Ensure any replacement maintains the 1.25 mm pitch, dual-row layout, and vertical SMT form factor. Cross-reference electrical ratings and mechanical dimensions before substitution.
