Overview
The G125-MH12605L3P is a male pin header from the Harwin Gecko-Latch series, designed for wire-to-board connections. It features a 1.25 mm pitch and a dual-row configuration with 26 positions (2x13). The connector utilizes a horizontal surface mount installation style with solder pin termination. Key mechanical specifications include a 3.3 mm contact length and PCB hold-down functionality without an integrated locking mechanism. The housing is constructed from polyamide material.
Feature Summary
- Gecko-Latch series design for secure board mounting
- Horizontal orientation for low-profile applications
- Male pin contacts for reliable signal transmission
- PCB hold-down feature for mechanical stability
Applications
- Wire-to-board interconnects in compact electronics
- Industrial control systems requiring robust mounting
- Consumer devices with space-constrained layouts
- Automotive electronic modules
Procurement Notes
Verify the specific suffix L3P against the manufacturer's official datasheet to confirm the 3.3mm height and horizontal orientation. Ensure compatibility with the target PCB footprint and mating connectors within the Gecko-Latch ecosystem before finalizing procurement orders.
Selection Notes
Select this component when a horizontal, low-profile header with 26 positions is required. The Gecko-Latch series offers enhanced retention compared to standard headers. Confirm that the absence of an active locking latch meets the mechanical security requirements of the assembly environment.
Part Context
This part belongs to the Harwin Gecko-Latch family, which specializes in high-reliability interconnect solutions. The series is characterized by its unique latching mechanisms and diverse form factors, catering to demanding environments where vibration resistance and secure connection integrity are critical performance factors.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Cross-reference with other Harwin Gecko-Latch variants only if electrical and mechanical parameters match exactly.
