Overview
The Harwin G125-MH11005L1R is a Gecko-SL series male pin header featuring a 1.25 mm pitch and two rows of five positions, totaling ten contacts. Designed for right-angle through-hole mounting, it utilizes gold-plated phosphor bronze terminals with a 3.3 mm tail length. The connector operates within a temperature range of -65°C to +150°C, supports a current rating of 2 A, and employs a jack-screw locking mechanism. Its green polyamide housing meets UL 94 V-0 flammability standards.
Feature Summary
- Patented four-finger copper alloy contact design ensures high reliability under extreme vibration conditions.
- Jack-screw board mount locking system provides secure mechanical retention.
- Low-profile geometry achieves significant space savings compared to larger pitch connectors.
Applications
- High-reliability electronic product designs requiring compact form factors
- Applications subject to extreme vibration environments
- Board-to-board or wire-to-board interconnections in demanding industrial settings
Procurement Notes
Verify the specific suffix 'L1R' against official datasheets to confirm reel packaging and orientation details. Ensure compatibility with mating sockets within the Gecko-SL family. Confirm RoHS compliance status via manufacturer documentation before integration into regulated assemblies.
Selection Notes
Select this component when right-angle through-hole installation is required for dense 1.25 mm pitch layouts. It suits designs needing robust vibration resistance and wide thermal operation. Verify that the 2 A current rating and 250 V voltage limits align with circuit requirements.
Part Context
This part belongs to the Harwin Gecko-SL family, engineered for miniature high-performance applications. The series offers a 35% space saving over Micro-D connectors while maintaining durability in harsh environments. It represents a specialized solution for constrained PCB real estate.
Replacement Considerations
No public confirmed substitute part numbers are available. Direct replacement requires identical Gecko-SL series specifications to maintain mechanical and electrical compatibility.
FAQ
What locking mechanism does the G125-MH11005L1R use?
It utilizes a jack-screw (screw-lok) board mount locking mechanism for secure attachment.
Is this connector suitable for high-vibration environments?
Yes, the patented four-finger contact design allows it to withstand extreme vibration, tested up to 100g.
