Overview
The G125-MV21005L0R is a Gecko-Latch series power-to-board connector manufactured by Harwin. It features a 1.25 mm pitch and a 10-position configuration arranged in two rows. The component utilizes gold-plated phosphor bronze contacts housed within a green polyamide (PA) shell. Rated for 2 A current and 250 V/450 V voltage, it supports solder termination with a straight mounting angle. Operating temperatures range from -65 C to +150 C, with an insulation resistance of 10 GOhms.
Feature Summary
- Gecko-Latch mechanical locking system ensures secure mating engagement
- Gold-plated phosphor bronze contacts provide reliable conductivity
- Polyamide housing offers high thermal stability up to 150 C
Applications
- Industrial control systems requiring robust power connections
- Telecommunications equipment infrastructure
- Automotive electronic modules
Procurement Notes
Verify the specific suffix codes against official Harwin documentation to confirm contact plating, housing color, and termination style. Ensure compatibility with mating connectors within the Gecko-Latch family. Confirm RoHS compliance status through the manufacturer's latest certification documents before finalizing procurement orders.
Selection Notes
Select this component when a vertical surface mount or through-hole header is required for compact power distribution. The 1.25 mm pitch allows for dense circuit board layouts. Consider the 2 A current rating per contact for load requirements. Verify that the jack-screw locking mechanism aligns with the assembly design constraints.
Part Context
This part belongs to the Harwin Gecko-Latch product line, designed for high-reliability interconnect solutions. The series is characterized by its unique screw-fixing mechanism and compact form factor. It serves as a standard solution for power-to-board applications where vibration resistance and secure connection are critical engineering priorities.
Replacement Considerations
Direct substitutes must match the 1.25 mm pitch, 10-position layout, and Gecko-Latch locking interface. Cross-reference with other Harwin G125 series headers ensuring identical electrical ratings and mechanical dimensions.
