4.1-9.5 connectors, also known as Mini DIN connectors, are high-power screw connectors operating in the DC-14 GHz range. Standardized in 2007 according to IEC 60169-11, they have been widely adopted to replace DIN 7-16 connectors due to their reduced size and weight. However, they are now being superseded by the new DIN 4.3-10 connector.
