G125-MS12005L1R

Overview

The Harwin G125-MS12005L1R is a Gecko-Latch series power-to-board connector designed for surface mount technology. It features a male pin configuration with a 1.25 mm pitch and a 2x3 position layout (6 positions total). The component utilizes phosphor bronze contacts with gold plating, housed in a green polyamide (PA) insulator. Rated for 2 A current and 250 V/450 V voltage, it operates within a temperature range of -65°C to +150°C. The unit offers an insulation resistance of 10 GOhms and is supplied in tape and reel packaging.

Feature Summary

• Integrated latch mechanism ensures secure mating retention between header and socket.
• Vertical surface mount design facilitates automated pick-and-place assembly processes.
• Gold-plated phosphor bronze contacts provide reliable electrical conductivity and corrosion resistance.

Applications

• High-density power distribution in compact electronic modules
• Surface mount interconnection in automotive control units
• Industrial equipment board-to-board power links

Procurement Notes

Verify the specific suffix 'L1R' against official Harwin documentation to confirm the exact contact count and reel specifications. Ensure compatibility with corresponding Gecko-Latch female sockets. Confirm RoHS compliance status through the manufacturer's latest environmental declarations prior to final procurement authorization.

Selection Notes

Select this component when a low-profile, latched SMT solution is required for 1.25 mm pitch applications. The 6-position variant suits limited space constraints. Validate that the 2 A current rating meets system thermal requirements. Ensure PCB footprint matches the vertical SMT reverse fix design specified in the datasheet.

Part Context

This part belongs to the Harwin Gecko-Latch family, engineered for high-reliability environments where vibration resistance is critical. The series combines standard power connector functionality with mechanical locking features, distinguishing it from non-latching counterparts in the broader G125 product line.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Cross-referencing requires matching pitch, latch type, and mounting style with alternative manufacturers.

FAQ

What is the function of the Gecko-Latch mechanism?

The Gecko-Latch mechanism provides a secure mechanical lock between the male header and female socket, preventing accidental disengagement due to vibration or shock.

What material is used for the housing?

The housing is constructed from Polyamide (PA), providing durability and thermal stability within the specified operating temperature range.
