G125-MH23405L2P

Overview

The G125-MH23405L2P is a Gecko-Latch male header connector manufactured by Harwin Inc. It features a 1.25mm pitch with 34 positions arranged in two rows. The connector utilizes through-hole mounting and includes a latch lock fastening mechanism for secure board-to-board or cable connections. Contact surfaces are gold-plated phosphor bronze, offering an 8.00µin thickness. The housing is constructed from halogen-free polyamide (PA4T) with a UL94 V-0 flammability rating and green insulation color. Rated current is 2A per contact, with an operating temperature range of -65°C to 150°C.

Feature Summary

• Integrated latch lock fastening system ensures secure mechanical retention between mating connectors.
• Gold-plated phosphor bronze contacts provide reliable electrical conductivity and corrosion resistance.
• Halogen-free PA4T insulation material meets UL94 V-0 fire safety standards.
• Vertical pin configuration supports standard through-hole PCB assembly processes.

Applications

• Board-to-board interconnections in industrial control systems
• Internal wiring harnesses within electronic enclosures
• Signal transmission modules requiring secure latching mechanisms

Procurement Notes

Verify the complete part number against the official Harwin component specification C125XX to ensure correct series and termination style. Confirm that the Gecko-Latch variant matches the required mechanical retention needs. Check for any specific ordering suffixes that may alter pin count or orientation. Ensure compatibility with mating female headers before procurement.

Selection Notes

Select this connector when a 1.25mm pitch male header with positive locking capability is required. The 34-position, 2-row layout suits applications needing high density without sacrificing retention strength. Consider the 2A current rating and wide temperature range for robust environmental performance. Verify PCB footprint dimensions match the design constraints.

Part Context

This component belongs to the Harwin Gecko-Latch series, designed for secure interconnect solutions. The G125 prefix indicates the 1.25mm pitch family. The MH designation specifies a male horizontal PC tail header. The 23405 code defines the 34-position, 2-row configuration with specific housing characteristics.

Replacement Considerations

No public confirmed substitute part numbers are available for direct replacement. Consult Harwin technical support for compatible alternatives within the Gecko-Latch series if this specific configuration is unavailable.
