Overview
The Harwin G125-MV21205L0R is a Gecko-Latch series power-to-board connector designed for vertical surface-mount technology applications. It features a 1.25 mm pitch with a 2x6 position configuration, totaling 12 contacts. The component utilizes phosphor bronze terminals with gold plating to ensure reliable electrical performance and corrosion resistance. Rated for 2 A current and 250 V/450 V voltage, it operates within a temperature range of -65 °C to +150 °C. The housing is constructed from polyamide (PA) with UL 94 V-0 flammability rating, providing high insulation resistance of 10 GOhms.
Feature Summary
- Vertical surface-mount design optimized for automated pick-and-place assembly processes.
- Gecko-Latch mechanism provides secure mating engagement between header and cable assemblies.
- Gold-plated phosphor bronze contacts ensure low contact resistance and long-term durability.
Applications
- Industrial control systems requiring compact power distribution
- Automotive electronics modules needing high-reliability connections
- Medical device internal wiring harnesses
Procurement Notes
Verify the specific ordering suffix against the official Harwin datasheet to confirm terminal length, latch type, and packaging format. Ensure compatibility with mating female connectors from the same Gecko-Latch family. Confirm RoHS compliance status and material declarations prior to final procurement approval.
Selection Notes
Select this component when vertical SMT mounting is required for space-constrained power applications. Consider the 1.25 mm pitch and 2A current rating for circuit requirements. Verify that the mating cable assembly supports the specified operating temperature range and voltage ratings.
Part Context
This part belongs to the Harwin Gecko-Latch family, known for robust latching mechanisms in power-to-board solutions. It serves as a male vertical header intended for direct PCB soldering, interfacing with corresponding female cable assemblies to establish secure power and signal paths in dense electronic environments.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Cross-reference with other Harwin Gecko-Latch variants only if pinout and mechanical dimensions match exactly.
