Overview
The Harwin G125-MH22605L2R is a male dual in-line horizontal through-board connector from the Gecko-Latch series. It features a 1.25 mm pitch and 26 positions arranged in two rows. The contacts are made of phosphor bronze with gold plating, rated for 2 A current and up to 450 VAC/DC voltage. The housing is constructed from polyamide (PA) with UL 94 V-0 flammability rating. Operating temperature ranges from -65°C to +150°C. Insulation resistance is specified at 10 GOhms. Termination is via solder pins.
Feature Summary
- Horizontal dual in-line male configuration for board-to-board or cable connections
- Gold-plated phosphor bronze contacts ensure reliable signal transmission
- Polyamide housing provides high thermal stability and flame resistance
Applications
- Industrial control systems requiring secure power distribution
- Automotive electronics harnesses
- Telecommunications equipment interconnects
Procurement Notes
Verify the specific pin count and row spacing against the target PCB footprint before ordering. Confirm that the mating connector belongs to the compatible Gecko-Latch series to ensure mechanical locking functionality. Check RoHS compliance documentation if required by project specifications. Ensure soldering profiles match the component's thermal limits.
Selection Notes
Select this part when a horizontal orientation is required for space-constrained designs. The dual-row layout supports higher density connections compared to single-row alternatives. Verify that the 1.25 mm pitch aligns with existing system standards. Consider the locking mechanism requirements for vibration-prone environments.
Part Context
This component belongs to Harwin's Gecko-Latch family, designed for robust connectivity in demanding applications. The series offers various configurations including vertical and right-angle options. The G125-MH22605L2R specifically addresses needs for horizontal mounting with secure latching capabilities.
Replacement Considerations
No direct public substitute part numbers are confirmed in the provided data. Cross-reference with other Harwin Gecko-Latch horizontal headers if availability is an issue. Ensure any alternative maintains the same pitch, current rating, and locking mechanism type.
