Introduction
Product Overview
The Gecko G125 Series 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 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. All variants feature gold-plated contacts for high performance and long service life, polarization to prevent mis-mating, and a low-profile potting wall for strain relief and improved sealing. Metal backshells are available for mechanical, RF, and EMC protection.
