G125-MH13405L1R

Overview

The G125-MH13405L1R is a male header connector from the Harwin Gecko-SL series, designed for high-reliability applications. It features a 1.25 mm pitch and a 2-row configuration with 34 positions. The component utilizes through-hole solder pin termination with a right-angle mounting style. Electrical ratings include a current capacity of 2 A per contact and an insulation resistance of 1 GOhms. The housing is constructed from green polyamide (PA) plastic with UL 94 V-0 flammability rating. Operating temperatures range from -65°C to +150°C.

Feature Summary

• Patented four-finger copper alloy contacts ensure secure connection under extreme vibration conditions.
• Jackscrew latching mechanism provides robust mechanical retention between mating components.
• Compact low-profile design achieves significant space savings compared to larger pitch connectors.

Applications

• Demanding industrial electronic systems requiring high reliability
• Extreme environment applications subject to severe vibration
• High-density board-to-board interconnects

Procurement Notes

Verify the specific suffix 'L1R' against official datasheets to confirm tape-and-reel packaging and orientation details. Confirm RoHS compliance status directly with the manufacturer as regulatory documentation may vary by production batch. Ensure mating socket compatibility within the Gecko-SL family before procurement.

Selection Notes

Select this part when a right-angle male header with jackscrew locking is required for dense signal routing. The 1.25 mm pitch allows for higher I/O density than standard 2.54 mm headers. Consider the 2 A current rating for power distribution needs and verify that the PCB layout accommodates the right-angle lead profile.

Part Context

This component belongs to the Harwin Gecko-SL family, which emphasizes high performance in miniature packages. The series is engineered to withstand Z-axis vibration up to 100g at 6m/s². The product line targets sectors where standard connectors fail due to environmental stress or space constraints.

Replacement Considerations

No public confirmed substitute part numbers are available. Direct replacement requires matching the 1.25 mm pitch, 34-position count, right-angle orientation, and jackscrew latching mechanism precisely.

FAQ

What is the latching mechanism type?

The connector uses a jackscrew latching system for secure retention.

Is the connector rated for high vibration?

Yes, it is tested to withstand Z-axis vibration of 100g at 6m/s².
