Overview
The Harwin G125-MH11205L7P is a Gecko-Latch male header connector featuring a 1.25mm (0.049 inch) pitch and two rows of six positions each, totaling twelve contacts. Designed for surface mount technology, it utilizes phosphor bronze pins with gold plating to ensure reliable signal transmission. The component supports a rated current of 2A and withstands voltages up to 450V AC/DC. Constructed from black polyamide insulation rated UL94 V-0, it operates within a temperature range of -65°C to +150°C.
Feature Summary
- Features a shrouded four-wall design to prevent pin misalignment during mating
- Incorporates a latch mechanism for secure board-to-board or wire-to-board connections
- Utilizes surface mount termination for automated PCB assembly processes
Applications
- Wire-to-board interconnections in compact electronic modules
- Board-to-board stacking in dense circuit architectures
- Signal routing in industrial control systems requiring secure locking
Procurement Notes
Verify the specific suffix 'L7P' against official Harwin documentation to confirm the exact reel configuration and tape-and-reel specifications. Ensure that the surface mount footprint matches the CAD model provided in the datasheet. Confirm RoHS compliance status through the manufacturer's latest environmental declaration before finalizing procurement orders.
Selection Notes
Select this component when a low-profile, latching solution is required for high-density applications. The 1.25mm pitch allows for significant I/O density within limited board areas. Consider the Gecko-Latch feature if vibration resistance and positive connection retention are critical operational requirements for the target environment.
Part Context
This part belongs to the Harwin Gecko family, known for micro-miniature connectivity solutions. The G125 series specifically targets space-constrained designs where reliability and ease of assembly are paramount. It complements other Gecko variants by offering specialized mounting styles and locking mechanisms tailored for diverse industrial and consumer electronics applications.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Direct replacement requires matching the 1.25mm pitch, 12-position count, dual-row configuration, and SMT mounting style.
