Overview
The G125-MV15005L0R is a 50-position male header connector from the Harwin Gecko-SL series. It features a 1.25 mm (0.049 inch) pitch with two rows of contacts. The component utilizes a vertical through-hole mounting style and solder pin termination for secure board attachment. Contacts are constructed from beryllium copper and finished with gold plating to ensure reliable conductivity. The housing is made of green nylon, providing insulation and structural support.
Feature Summary
- High-reliability design engineered for extreme shock, vibration, and temperature conditions
- Jackscrew locking mechanism ensures secure mating and prevents accidental disconnection
- Gold-plated beryllium copper contacts provide durable electrical performance
Applications
- Industrial control systems requiring robust connectivity
- Automotive electronics exposed to high vibration
- Aerospace and defense equipment demanding high reliability
- Test and measurement instrumentation
Procurement Notes
Verify the specific ordering suffix L0R against official Harwin documentation to confirm tape-and-reel packaging and lead time requirements. Ensure compatibility with automated pick-and-place assembly processes if applicable. Cross-reference the full part number to distinguish between reel and bulk packaging variants within the same product family.
Selection Notes
Select this component when a vertical male header with jackscrew locking is required for high-vibration environments. The 1.25 mm pitch allows for dense circuit layouts while maintaining adequate spacing. Verify that the board layout supports the through-hole solder pin termination and accommodates the physical dimensions of the jack screw mechanism during assembly.
Part Context
This part belongs to the Gecko-SL series, which is designed for harsh environments. The series offers various configurations including right-angle and straight headers. The G125-MV15005L0R specifically provides a 50-contact solution in a dual-row arrangement, suitable for applications needing substantial signal or power distribution in a compact form factor.
Replacement Considerations
Compatible counterparts include G125-MV15005L0P and G125-MV15005L1P. These variants share identical electrical and mechanical specifications but differ in packaging format. Confirm that the alternative packaging meets the specific manufacturing and handling requirements of the production line.
