G125-MS12605L2R

Overview

The Harwin G125-MS12605L2R is a Gecko-SL series power-to-board header featuring male pin contacts with a 1.25 mm pitch. It offers 26 positions arranged in two rows, designed for vertical surface mount installation. The connector supports a current rating of 2 A and voltage ratings up to 450 VAC/DC. Constructed with gold-plated phosphor bronze contacts and polyamide insulation, it operates within a temperature range of -65°C to +150°C. The unit includes screw fixings with board mount studs and utilizes tape-and-reel packaging for automated pick-and-place assembly.

Feature Summary

• Vertical surface mount design with integrated screw fixings and board mount studs for secure mechanical attachment.
• Gold-plated phosphor bronze contacts ensure reliable electrical performance and corrosion resistance.
• Polyamide insulation housing provides UL94 V-0 flammability rating and high thermal stability.
• Tape-and-reel packaging facilitates efficient automated pick-and-place manufacturing processes.

Applications

• Industrial control systems requiring robust power distribution
• Automotive electronics demanding high-temperature reliability
• Consumer appliances needing compact power-to-board connections
• Telecommunications infrastructure equipment

Procurement Notes

Verify the specific suffix L2R indicates tape-and-reel packaging configuration rather than bulk supply. Confirm that the 2x13 contact layout matches the target PCB footprint requirements. Ensure compatibility with the Gecko-SL mating socket series for proper engagement. Check RoHS compliance documentation for final assembly regulations. Validate that the 450V rating meets the system's electrical isolation standards.

Selection Notes

Select this component when vertical SMT mounting with mechanical screw fixation is required. The 1.25 mm pitch allows for dense power routing on limited board space. Choose this part for applications exceeding standard temperature limits due to its +150°C capability. Consider the gold plating for environments requiring long-term contact integrity. Verify that the 2A current rating suffices for the intended power load without derating issues.

Part Context

This connector belongs to Harwin's Gecko-SL family, known for high-density power solutions. The G125 series specifically targets applications needing reliable interconnects in confined spaces. As a power-to-board header, it bridges main power sources to circuit boards efficiently. The Gecko-SL line emphasizes durability and ease of automation in modern electronics manufacturing.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Cross-reference with other Harwin Gecko-SL variants only if they share identical mechanical dimensions and electrical ratings. Verify compatibility before substituting any similar connectors from different manufacturers.
