G125-MV12005M3P

Overview

The Harwin G125-MV12005M3P is a Gecko-SL series power-to-board connector designed for high-density applications. It features a 1.25 mm pitch with 20 positions arranged in a dual row configuration. The component utilizes male pin contacts made of phosphor bronze with gold plating, ensuring reliable signal and power transmission. Rated for 2 A current and 450 V voltage, it supports an operating temperature range from -65 °C to +150 °C. The housing is constructed from polyamide (PA) with UL 94 V-0 flammability rating. This right-angle through-hole connector incorporates reverse fix hex socket screw-locking mechanisms for secure board mounting.

Feature Summary

• Dual-row shrouded design with 1.25 mm pitch for compact high-density interconnects
• Reverse fix hex socket screw-locking mechanism ensures secure mechanical retention
• Gold-plated phosphor bronze contacts provide corrosion resistance and low contact impedance
• Polyamide housing offers thermal stability and UL 94 V-0 flame retardancy

Applications

• Industrial control systems requiring robust power distribution
• Telecommunications equipment with high-density board-to-board connections
• Automotive electronics demanding wide temperature tolerance
• Medical devices needing reliable signal integrity

Procurement Notes

Verify the specific suffix M3P against the official Harwin datasheet to confirm the reverse fix locking feature and right-angle orientation. Ensure compatibility with mating female connectors within the Gecko-SL family. Check RoHS compliance status via the manufacturer's documentation before integration into regulated products.

Selection Notes

Select this component when high-density power delivery is required alongside secure mechanical locking. The right-angle through-hole style suits space-constrained PCB layouts. Verify that the 2 A current rating per contact meets system requirements. Consider the 1.25 mm pitch for trace routing density compared to larger spacing alternatives.
