Gecko-MT 1.25mm Mixed Layout Connectors

Harwin Gecko-MT 1.25mm Pitch Mixed Layout Connector combines the 2A Gecko signal contact with 10A power contacts in the same lightweight and compact housing. The connectors are designed for high-performance applications in the most extreme environments when size, weight, and power (SWaP) requirements matter most. Cable-to-board, board-to-board, and cable-to-cable options are available in pin layouts of 1+8+1 or 2+8+2 contact configurations. Other features include mate-before-lock stainless steel jackscrews in both standard or reverse-fix, ensuring secure connection, and lightweight metal hoods for additional cable protection and shielding. Harwin Gecko-MT applications include aviation, motorsport and electric vehicles, space equipment, and defence and security.
