Overview
The Harwin G125-MH13405L1P is a male, dual-in-line horizontal header from the Gecko-Latch series. It features 34 positions with a 1.25 mm pitch and 1.25 mm row spacing. Designed for through-hole right-angle installation, it utilizes gold-plated phosphor bronze contacts rated for 2 A current. 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 1 GOhm.
Feature Summary
- Jackscrew locking mechanism ensures secure mating retention
- High-reliability dual-in-line horizontal configuration
- Gold-plated contacts provide corrosion resistance
Applications
- Secure board-to-board interconnects requiring mechanical retention
- High-reliability industrial control systems
- Automotive electronic modules
Procurement Notes
Verify the specific suffix L1P against official datasheets to confirm jack-screw locking functionality and contact plating specifications. Ensure compatibility with mating sockets in the same Gecko-Latch series. Confirm RoHS compliance status via manufacturer documentation before integration into regulated assemblies.
Selection Notes
Select this component when high-mate/unmate durability and positive locking are required. The horizontal orientation suits space-constrained PCB layouts. Verify that the 1.25 mm pitch matches existing footprint requirements. Ensure the 2 A current rating meets circuit load demands without derating issues.
Part Context
Part of the Harwin Gecko-Latch family, designed for demanding environments. The series emphasizes robust mechanical retention through screw-locking technology. This model represents a standard pin header variant within the broader connector ecosystem, focusing on reliability over simple snap-fit designs.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided data. Cross-reference only with exact series equivalents if modification is necessary.
FAQ
What type of locking mechanism does this connector use?
It uses a jackscrew locking mechanism for secure retention.
Is this connector suitable for high-vibration environments?
Yes, the jack-screw design provides enhanced stability compared to standard headers.
