Overview
The G125-MS11205M3R is a Gecko-Latch series header connector manufactured by Harwin Inc. It features a 1.25 mm pitch with 12 positions arranged in a 2x6 configuration. Designed for surface mount installation, this male pin connector utilizes solder termination and phosphor bronze contacts with gold plating. The housing is constructed from black polyamide (PA4T) glass-filled material rated UL94 V-0. It supports a maximum current of 2 A and withstands voltages up to 450 VAC/DC across an operating temperature range of -65°C to +150°C.
Feature Summary
- Patented four-finger copper alloy contact design ensures high reliability under extreme vibration conditions.
- Low-profile geometry provides significant space savings compared to other high-performance connectors.
- Board lock feature secures the connector firmly to the printed circuit board during assembly.
Applications
- Demanding electronic product designs requiring high performance in miniature packages
- Applications subject to extreme vibration environments
- Systems operating within wide temperature ranges
Procurement Notes
Verify the specific suffix 'M3R' against official Harwin documentation to confirm reel packaging specifications and tape dimensions. Ensure compatibility with automated pick-and-place equipment requirements. Confirm RoHS compliance status through the manufacturer's latest environmental declarations before procurement.
Selection Notes
Select this component when a low-profile, high-reliability surface mount header is required. The 1.25 mm pitch allows for dense circuit layouts while maintaining 2 A per contact ratings. Consider the Gecko-Latch series benefits for applications needing robust mechanical retention and resistance to harsh environmental factors.
Part Context
This part belongs to the Harwin Gecko family, which includes various interconnect solutions like Datamate and Kona. The G125 series specifically targets applications where space constraints and high reliability are critical. It complements the broader portfolio of high-performance connectors designed for demanding industrial and electronic uses.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided data. Consult Harwin technical support for cross-reference information if alternative sourcing is necessary.
