Overview
The Harwin G125-MH124M3-02AD000P is a Gecko-MT series power-to-board connector featuring a horizontal, right-angle through-hole mounting style. It comprises 26 positions arranged in two rows with a 1.25 mm pitch and row spacing. The assembly includes male pins with gold plating on phosphor bronze contacts, housed in green polyamide (PA) insulation rated UL 94 V-0. Designed for board-level interconnects, it supports a maximum operating temperature of +150°C and utilizes a screw-locking mechanism for secure mating.
Feature Summary
- Horizontal screw-locking design ensures secure mechanical retention between header and housing.
- Integrated power and signal configuration combines 24 signal positions with 2 dedicated power positions.
- Right-angle through-hole termination facilitates compact vertical board stacking applications.
Applications
- Industrial control systems requiring robust power delivery
- Embedded computing hardware with mixed-signal interfaces
- Automotive electronics modules needing high-reliability connections
Procurement Notes
Verify the specific ordering suffix to confirm the exact pin count and locking mechanism variant. Ensure compatibility with the corresponding Gecko-MT female housing for proper mating. Confirm that the PCB footprint matches the 1.25 mm pitch and right-angle solder pin dimensions specified in the official datasheet before finalizing procurement.
Selection Notes
Select this component when a horizontal orientation with mechanical locking is required for power distribution. The mixed signal-power layout reduces board space compared to separate connectors. Verify that the 2 A current rating per contact aligns with the system's electrical load requirements and thermal management capabilities.
Part Context
This part belongs to the Harwin Gecko-MT series, designed for high-density power-to-board applications. The series emphasizes secure mechanical retention through screw-locking features, distinguishing it from standard push-pull or latch-based connectors within the broader Gecko product family.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Direct replacement requires matching the 1.25 mm pitch, 26-position count, and horizontal screw-locking interface specifications exactly.
