Introduction
Product Overview
The Gecko G125 Series from Harwin offers 1.25mm pitch high-reliability rectangular connectors designed for various interconnecting applications including cable-to-cable, cable-to-board, and board-to-board. These fully shrouded, unsealed connectors are available in three non-intermateable variants: Gecko-SL (Screw-Lok) with floating screws for robust interconnection, Gecko-MT (Mixed Technology) featuring both signal and power contacts, and the original Gecko Latch design with easy-release locking latches. They are ideal for applications requiring secure and reliable connections, with options for backpotting for enhanced strain relief and sealing. All contacts are gold-plated for high performance and longevity.
