G125-MS12005M1P

Overview

The Harwin G125-MS12005M1P is a Gecko-SL series power-to-board header connector designed for surface mount technology. It features a male pin configuration with a 1.25 mm pitch and a 2x10 position layout (20 total contacts). The component utilizes phosphor bronze contacts with gold plating, housed in green polyamide insulation. Rated for 2 A current and 250 V/450 V voltage, it operates within a temperature range of -65°C to +150°C. This specific variant includes reverse fix tape for automated pick-and-place assembly.

Feature Summary

• Reverse fix tape integration facilitates automated SMT pick-and-place manufacturing processes.
• Male pin contact design ensures secure mating with corresponding socket connectors.
• Polyamide housing provides high thermal stability and electrical insulation properties.

Applications

• High-density power distribution on printed circuit boards
• Automated surface mount assembly lines requiring reverse fix tape compatibility
• Industrial electronics utilizing Gecko-SL interconnect systems

Procurement Notes

Verify the reverse fix tape specification against your SMT machine requirements before procurement. Confirm that the 1.25 mm pitch and 2x10 configuration match your PCB footprint exactly. Ensure the manufacturer's datasheet is consulted for reflow soldering profiles to maintain connection integrity during assembly.

Selection Notes

Select this model when automated placement efficiency is required due to its reverse fix tape feature. Compare against standard G125 headers if tape compatibility is not needed. Verify that the 2 A current rating and 250 V voltage limits are sufficient for the target application's electrical load requirements.

Part Context

This component belongs to the Harwin Gecko-SL family, which specializes in compact, high-reliability power interconnects. The G125 designation indicates the 1.25 mm pitch standard. As a power-to-board solution, it bridges main power sources to sub-circuits, offering a robust alternative to traditional wire harnesses in space-constrained electronic designs.

Replacement Considerations

G125-MS12005L2P: Standard SMT header without reverse fix tape; requires manual or different automated handling methods. G125-MS12005L3R: Gecko-Latch series variant with latch mechanism; verify mechanical retention needs differ from standard press-fit.
