Overview
The G125-MV11205M3R is a Gecko-SL series header connector manufactured by Harwin Inc. It features a 12-position, 2-row male pin configuration with a 1.25 mm pitch. Designed for through-hole mounting at a right angle, it utilizes gold-plated phosphor bronze contacts rated for 2 A current. The housing is constructed from green polyamide material, offering a UL 94 V-0 flammability rating and an operating temperature range of -65°C to +150°C.
Feature Summary
- Right-angle through-hole mounting design for space-efficient board integration
- Gold-plated phosphor bronze contacts ensure reliable signal transmission
- Green polyamide housing provides high thermal stability and flame resistance
Applications
- Wire-to-board interconnections in industrial equipment
- Signal routing in automotive electronic control units
- General-purpose circuit board assembly requiring robust headers
Procurement Notes
Verify the specific suffix 'M3R' against official Harwin documentation to confirm tape-and-reel packaging specifications. Ensure compatibility with mating sockets within the Gecko-SL family. Confirm RoHS compliance status via the latest datasheet before finalizing procurement orders.
Selection Notes
Select this component when a right-angle, through-hole male header is required for 1.25 mm pitch applications. The 12-position count suits moderate-density connections. Verify that the 2 A current rating and -65°C to +150°C temperature range meet the system's electrical and environmental requirements.
Part Context
This part belongs to the Harwin Gecko-SL series, known for high-reliability signal connectors. The G125-MV11205M3R specifically addresses needs for vertical or angled board-to-board connections where space constraints necessitate a right-angle profile while maintaining standard 1.25 mm spacing.
Replacement Considerations
Compatible substitutes include other 12-position, 2-row, right-angle Gecko-SL headers from Harwin, such as G125-MV11205M1R or G125-MV11205M2P, provided the packaging and exact contact plating specifications match the design requirements.
