Overview
The Harwin G125-MS13405M2P is a Gecko-SL series male header connector designed for surface-mount technology. It features a 1.25 mm pitch and a 2x17 position configuration, totaling 34 contacts. The connector utilizes gold-plated beryllium copper contacts housed in a green nylon body. Rated for 2 A current and operating within a temperature range of -65 C to +150 C, it provides a low-profile interconnect solution suitable for board-to-board or cable applications.
Feature Summary
- Low-profile dual-row design optimized for stacking and space-constrained environments
- Surface-mount termination with vertical orientation for automated assembly
- Gold-plated beryllium copper contacts ensuring reliable electrical performance
Applications
- Board-to-board interconnects in compact electronic assemblies
- Cable-to-board connections requiring secure latching
- Stacking configurations in modular hardware systems
Procurement Notes
Verify the specific ordering suffix against official Harwin documentation to ensure correct contact plating, housing material, and packaging format. Confirm that the surface-mount footprint matches the target PCB design guidelines. Check for RoHS compliance status and environmental certifications relevant to the intended deployment region before finalizing procurement orders.
Selection Notes
Select this component when a low-profile, high-density power or signal connection is required on a printed circuit board. Ensure the application environment stays within the specified -65 C to +150 C operational temperature range. Verify that the 2 A current rating per contact aligns with the system's electrical load requirements and that the 1.25 mm pitch accommodates the available board spacing constraints.
Part Context
This part belongs to the Harwin Gecko-SL family, which specializes in robust, low-profile connectors for demanding industrial and consumer electronics. The series emphasizes secure mechanical retention and reliable electrical connectivity in tight spaces. As a male header, it pairs with corresponding female receptacles to form complete interconnect solutions.
Replacement Considerations
Direct substitutes within the same Gecko-SL series include G125-MV13405M3P for through-hole mounting or other SMT variants with different pin counts such as G125-MS11605M2P. Verify mechanical compatibility and electrical ratings before swapping components.
