G125-MV23405L2R

Overview

The Harwin G125-MV23405L2R is a Gecko-SL series power-to-board connector designed for vertical through-board mounting. It features a male header configuration with 34 positions arranged in two rows, utilizing a 1.25mm pitch. The contacts are gold-plated phosphor bronze pins with a contact length of 4.50mm and an insulation height of 4.90mm. Rated for 2A per contact, the component operates within a temperature range of -65°C to 150°C. It includes board lock features and is supplied in tape and reel packaging for pick-and-place assembly.

Feature Summary

• Vertical through-board male header design with screw fixings and board mount studs
• Gold-plated phosphor bronze contacts ensuring reliable signal integrity
• Halogen-free polyamide (PA4T) insulation material rated UL94 V-0
• Integrated board lock mechanism for secure mechanical attachment

Applications

• Industrial control systems requiring robust power distribution
• Automotive electronics assemblies needing high-reliability connections
• Telecommunications infrastructure equipment
• Medical device internal power routing

Procurement Notes

Verify the specific ordering suffix against the official Harwin datasheet to confirm pin count, plating thickness, and packaging type. Ensure compatibility with mating female connectors from the same Gecko-SL family. Confirm that the PCB footprint matches the specified 1.25mm pitch and 4.50mm contact length requirements before finalizing procurement orders.

Selection Notes

Select this component when a vertical, screw-fixed power connection is required for high-density applications. The 34-position layout supports substantial current distribution across multiple circuits. Consider the 2A rating per contact for thermal management planning. The halogen-free material selection aligns with environmental compliance standards for sensitive electronic enclosures.

Part Context

This part belongs to the Harwin Gecko-SL series, which provides high-reliability interconnect solutions. The series is known for its compact form factor and robust mechanical performance. The G125-MV23405L2R specifically addresses needs for vertical mounting configurations where space efficiency and secure locking mechanisms are critical for long-term operational stability.

Replacement Considerations

Direct substitutes must match the 1.25mm pitch, 34-pin count, and vertical orientation. Verify that alternative components support the same 2A current rating and operating temperature range. Ensure mechanical compatibility with existing board mount studs and screw fixation methods to maintain assembly integrity.
