Harwin G125-2040696L0
Product Overview
The Gecko G125 Series are 1.25mm pitch high-reliability rectangular connectors designed for various interconnecting applications including cable-to-cable, cable-to-board, and board-to-board. They are fully shrouded, unsealed connectors featuring gold-plated contacts for high performance and long service life. The series offers three non-intermateable variants: Gecko-SL (Screw-Lok) for robust interconnection, Gecko-MT (Mixed Technology) with signal and power contacts, and the original Gecko Latch design with easy-release locking latches. Housings are polarized to prevent mis-mating. Metal backshells are available for mechanical, RF, and EMC protection.
