Gecko-MT Mixed Layout Connector
Harwin's Gecko-MT connectors are high-reliability signal and power connections on a 1.25 mm pitch
Harwin's Gecko-MT range combines the 1.25 mm pitch Gecko signal connector system with mixed technology layouts, adding 10 A power contacts to the range. They are the smallest and lightest mixed-layout connector currently available for high-performance applications. Gecko is the ideal choice when SWaP matters most. The connectors feature cable-to-board, board-to-board, and cable-to-cable configurations. Stainless steel jackscrews are available in both standard or reverse-fix, ensuring the security of connection in the most extreme environments. Lightweight metal hoods give additional cable protection and EMI/RFI shielding.
