G125-MV23405L0P

Overview

The Harwin G125-MV23405L0P is a Gecko-SL series power-to-board connector designed for vertical through-hole mounting. It features a male pin configuration with 34 positions arranged in a dual-row layout. The component utilizes a 1.25 mm pitch and supports a current rating of 2 A per contact at a voltage of 250 V. Constructed with phosphor bronze contacts plated with gold, it ensures reliable performance within an operating temperature range of -65°C to +150°C. The housing is made from green polyamide (PA4T) with UL 94 V-0 flammability rating.

Feature Summary

• Patented four-finger contact design maintains electrical connection under high vibration and shock conditions
• Integrated board lock mechanism secures the connector to the PCB during assembly and operation
• Compatible with automated pick-and-place manufacturing processes for efficient surface mounting

Applications

• High-reliability industrial control systems requiring robust power distribution
• Automotive electronics exposed to significant mechanical stress and vibration
• Aerospace and defense equipment demanding verified shock resistance

Procurement Notes

Verify that the specific part number matches the required 34-position vertical male configuration. Confirm that the tape and reel packaging aligns with your automated assembly equipment specifications. Ensure the phosphor bronze material and gold plating meet your corrosion resistance requirements. Check that the UL 94 V-0 insulation rating satisfies your safety compliance standards. Validate the 1.25 mm pitch compatibility with your mating socket connectors before finalizing procurement.

Selection Notes

Select this component when high mechanical durability is critical due to its patented four-finger contact technology. Choose the vertical orientation for space-constrained boards where height is limited but depth is available. Consider the integrated board lock if additional retention force is needed beyond standard solder joints. Ensure the 2 A current rating meets the thermal dissipation needs of your circuit. Verify that the green polyamide housing color aids in visual inspection during production.

Part Context

This connector belongs to the Gecko-SL family, which emphasizes high reliability in harsh environments. The series is engineered for applications involving severe shock and vibration. It complements other Gecko-SL variants by offering specific positioning and mounting options. The design philosophy focuses on maintaining electrical integrity without relying solely on solder strength.

Replacement Considerations

Direct substitutes include other Harwin Gecko-SL vertical male headers with identical 34-position counts and 1.25 mm pitch. Compatible alternatives must feature similar four-finger contact designs for equivalent vibration resistance. Ensure any replacement maintains the same UL 94 V-0 rating and operating temperature range. Verify that the board lock mechanism is present if retention is required.

FAQ
