G125-MV12005L0P

Overview

The Harwin G125-MV12005L0P is a Gecko series power-to-board header featuring male pins with a 1.25mm pitch. It comprises 6 positions arranged in a 2-row configuration, designed for surface mount installation. The connector utilizes phosphor bronze contacts with gold plating and polyamide insulation rated UL94 V-0. It supports a maximum current of 2A and withstands voltages up to 450V AC/DC across an operating temperature range of -65°C to +150°C.

Feature Summary

• Features a secure pin-locking mechanism to prevent accidental disengagement during mating cycles.
• Incorporates a board-lock feature that anchors the connector firmly to the PCB substrate.
• Constructed with high-temperature resistant polyamide insulation suitable for reflow soldering processes.

Applications

• Industrial control system interconnections
• Power distribution modules within electronic assemblies
• Automotive electronics harness connections

Procurement Notes

Verify the specific suffix codes against the manufacturer datasheet to confirm exact pin count, row configuration, and termination style. Ensure compatibility with automated surface mount equipment specifications. Cross-reference insulation material ratings and contact plating thickness requirements against application environmental standards before finalizing procurement orders.

Selection Notes

Select this component when a low-profile, high-reliability connection is required for power or signal transmission in dense PCB layouts. The 1.25mm pitch allows for higher density compared to standard 2.54mm headers while maintaining robust mechanical locking. Consider the surface mount orientation and thermal resistance limits when evaluating suitability for high-current applications.

Part Context

This part belongs to the Harwin Gecko family, known for its unique positive locking mechanism that ensures secure mating without external latches. The G125 designation indicates the 1.25mm pitch series. As a male header, it is designed to mate with corresponding female sockets or cable assemblies, providing a stable electrical interface for board-to-board or wire-to-board connections.

Replacement Considerations

Direct substitutes must match the 1.25mm pitch, 2x3 pin configuration, and surface mount mounting style. Verify that alternative components offer equivalent UL94 V-0 insulation ratings and comparable current carrying capacities. Ensure the replacement maintains the same mechanical locking features if vibration resistance is critical to the design.

FAQ

What is the primary locking mechanism of this connector?

It utilizes a proprietary pin-locking system that secures the male pins into the mating socket, preventing accidental disconnection.

Is this connector suitable for high-temperature environments?

Yes, it is rated for operation from -65°C to +150°C and uses UL94 V-0 rated polyamide insulation.
