Product Overview

The Gecko G125 Series from Harwin are 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) for robust interconnection with floating screws, Gecko-MT (Mixed Technology) for combined signal and power contacts, and the original Gecko Latch design with easy-release locking latches. They feature low-profile potting walls for strain relief and improved sealing, gold-plated contacts for high performance and longevity, and polarization to prevent mis-mating. Metal backshells are available for mechanical, RF, and EMC protection.
