Radio-frequency connectors - Part 7: R.F. coaxial connectors with inner diameter of outer conductor 9.5 mm (0.374 in) with bayonet lock - Characteristic impedance 50 ohms (Type C)
Gives the dimensions for r.f. coaxial connectors which may preferably be used with r.f. cables 96 IEC 60050-7. These connector patterns are for medium power, quick disconnect applications using a bayonet type coupling mechanism.
