Overview
The Harwin G125-MV13405M1R is a Gecko-SL series power-to-board connector featuring a 1.25mm pitch male header with 34 positions arranged in two rows. It utilizes vertical through-hole solder pin termination and includes screw fixings with 5mm board mount studs for secure attachment. The contacts are gold-plated beryllium copper rated for 2A per contact, supporting 1000 mating cycles. Operating temperatures range from -65°C to +150°C.
Feature Summary
- Patented four-finger contact design ensures reliable electrical connection under high vibration and shock conditions
- Integrated screw fixing mechanism with 5mm board mount studs provides robust mechanical stability
- Gold-plated beryllium copper contacts offer durability and consistent signal integrity
Applications
- High-reliability industrial equipment requiring vibration resistance
- Power distribution systems needing secure board-to-board connections
- Automotive electronics subject to shock and environmental stress
Procurement Notes
Verify the specific suffix 'R' indicates tape and reel packaging configuration against official datasheets. Confirm RoHS compliance status and current lifecycle stage as availability may be restricted. Ensure compatibility with mating female connectors within the same Gecko-SL family before procurement.
Selection Notes
Select this component when high reliability under mechanical stress is required. The 1.25mm pitch allows for dense circuit layouts while maintaining 2A current capacity per contact. Verify that the vertical orientation and screw-fixing requirements align with the assembly design constraints.
Part Context
This part belongs to the Harwin Gecko-SL series, designed for demanding applications. It complements other Gecko-SL headers and sockets, offering a standardized 1.25mm interface. The series supports various configurations including coaxial and signal variants for comprehensive system integration.
Replacement Considerations
Check for direct substitutes within the Gecko-SL family such as G125-MV13405M1P for different packaging. Ensure any replacement maintains the 1.25mm pitch, 34-position count, and vertical mounting style to preserve mechanical and electrical compatibility.
