The OPTIMA D Series has been designed to meet the demands of modern miniature systems when failure is not an option.  Engineered with a new patented latching ring, this connector is optimized for high vibration resistance and unparalleled reliability. Its lightweight, low-profile structure is combined with a stealth, non-reflective, conductive surface treatment, making it ideal for military and aerospace applications. Built to withstand most demanding requirements, Optima’s D Series has been tested according to military standards such as MIL-STD-810H.  Thanks to LEMO’s modular connector design, the OPTIMA D series integrates configurations from other series, offering a variety of multipole combinations, high-speed data transfer options via USB and Ethernet protocols, and high frequency coaxial solutions.
