Overview
The Harwin G125-MS12005M3P is a male pin header from the Gecko-SL series, designed for power-to-board applications. It features a 1.25 mm pitch with a 2x10 contact arrangement (20 positions). The connector utilizes gold-plated phosphor bronze contacts and a polyamide insulation body. It supports through-hole mounting with solder pins and includes reverse fixings for secure attachment.
Feature Summary
- Features a 1.25 mm pitch design for compact high-density connections
- Includes reverse fixings to ensure secure board mounting
- Utilizes gold-plated phosphor bronze contacts for reliable conductivity
Applications
- Power distribution in electronic assemblies
- High-reliability interconnects requiring secure mounting
- Compact circuit board connections
Procurement Notes
Verify the specific suffix 'P' against official documentation to confirm packaging or variant details, as ordering suffixes may indicate specific configurations. Ensure compatibility with mating sockets within the Gecko-SL family. Confirm that the reverse fixing mechanism meets the mechanical requirements of the target application before procurement.
Selection Notes
Select this component when a male header with secure reverse fixings is required. The 1.25 mm pitch allows for dense layouts. Verify that the 20-position configuration matches the circuit design. Ensure the through-hole solder pin style is compatible with the PCB manufacturing process and thermal profiles.
Part Context
This part belongs to the Harwin Gecko-SL series, known for high-reliability interconnect solutions. The series offers various configurations including headers, cable assemblies, and power connectors. The Gecko-SL line is designed for demanding environments, providing robust performance and secure locking mechanisms across different form factors.
Replacement Considerations
Compatible mates are female sockets within the same Gecko-SL 1.25 mm pitch series. Verify that any substitute maintains the 2x10 position count and reverse fixing feature. Ensure electrical ratings and material specifications match the original requirements.
