G125-MS13405L1P

Overview

The Harwin G125-MS13405L1P is a Gecko-Latch series power-to-board connector featuring 34 positions in a 2-row configuration. It utilizes a 1.25 mm pitch male pin interface with surface mount termination. The component supports a current rating of 2 A per contact and voltage ratings of 250 V or 450 V. Constructed with phosphor bronze contacts gold-plated and a polyamide (PA) housing, it operates within a temperature range of -65 C to +150 C. The unit provides high reliability with 1000 mating cycles.

Feature Summary

• Gecko-Latch mechanism ensures secure connection stability
• High durability rated for 1000 mating cycles
• Vertical surface mount design for compact integration

Applications

• Board-to-board interconnects
• Board-to-cable interconnects
• Demanding electronic system integration

Procurement Notes

Verify the specific Gecko-Latch variant against standard vertical headers to ensure mechanical locking requirements are met. Confirm that the 1.25 mm pitch and 34-position count align with the target PCB footprint. Validate the polyamide housing material compatibility with intended thermal environments. Ensure the surface mount soldering profile supports the specified operating temperature limits during assembly.

Selection Notes

Select this model when a latching mechanism is required for vibration resistance in board-to-board applications. The 2 A current rating suits signal and low-power distribution needs. Consider the vertical orientation for space-constrained layouts. Verify that the 1.25 mm pitch matches existing design constraints. The gold plating on phosphor bronze contacts offers reliable conductivity for repeated engagement scenarios.

Part Context

This component belongs to the Harwin G125 Gecko family of high-reliability connectors. The series is designed for demanding industrial and commercial applications requiring robust interconnect solutions. The Gecko-Latch sub-series specifically adds mechanical locking features to enhance connection security compared to standard header variants.

Replacement Considerations

Direct substitutes include other Harwin G125 series parts with matching 1.25 mm pitch and 34 positions, such as G125-MV13405M3P for through-hole mounting if surface mount is not feasible. Ensure any replacement maintains the Gecko-Latch functionality if mechanical retention is critical.
