Rectangular Connectors Featuring Harwin G125-9642600 Gecko G125 Series 125mm Pitch High Reliability
Product Overview
The Gecko G125 Series by 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 connections, Gecko-MT (Mixed Technology) supporting both signal and power contacts, and the original Gecko Latch design with easy-release locking latches. All connectors feature gold-plated contacts for high performance and longevity, polarized housings 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.
