G125-MV11205L1P

Overview

The Harwin G125-MV11205L1P is a Gecko-SL series power-to-board connector designed for high-reliability applications. It features a male pin configuration with 12 positions arranged in a dual-row layout. The component utilizes a 1.25 mm pitch and is intended for through-hole mounting with straight, top-entry solder termination. Electrical ratings include a current capacity of 2 A per contact and voltage ratings up to 450 V. The housing is constructed from green nylon, while contacts are made of beryllium copper with gold plating. It supports an operating temperature range from -65 C to +150 C and offers 1000 mating cycles.

Feature Summary

• High durability with 1000 mating cycles for reliable long-term performance
• Compact dual-row design utilizing a 1.25 mm pitch for dense board layouts
• Robust construction with gold-plated beryllium copper contacts and nylon housing

Applications

• Industrial control systems requiring high-reliability power connections
• Automotive electronics demanding durable interconnects
• Medical equipment needing stable signal and power transmission
• Consumer electronics with space-constrained power delivery needs

Procurement Notes

Verify the specific ordering suffix L1P to ensure correct packaging and orientation specifications. Confirm that the 1.25 mm pitch and 12-position count align with the target PCB footprint. Check RoHS compliance status if required by project regulations. Ensure the through-hole solder termination method matches the assembly process capabilities. Validate the voltage rating against the system's maximum operational requirements.

Selection Notes

Select this component when a shrouded, vertical male header is required for power-to-board interfaces. The 1.25 mm pitch allows for higher density compared to larger spacing options. Consider the 2 A current rating per contact for load calculations. The straight mounting style suits standard vertical board connections. Gold plating ensures low contact resistance and corrosion resistance in harsh environments.

Part Context

This part belongs to the Harwin Gecko-SL family, which provides high-reliability interconnect solutions. The series is known for its robust mechanical design and consistent electrical performance. Components in this line are engineered for demanding environments where vibration and thermal cycling are concerns.
