The standards of the EN 4652 series describe coaxial high-frequency connectors which are used with flexible high-frequency cables according to EN 4604-001 and semi-rigid coaxial cables in the aerospace industry. This connector family is derived from connectors according to MIL-PRF-39012. The dimensions of the front are identical and the products can be coupled together. Part 113 specifies the characteristics of bayonet coupling (BNC interface) coaxial bulkhead receptacle - 50 ohms. The cable to connector assembly is a clamp technology. The standards of the EN 4652 series are prepared by the ASD-STAN, Technical Section Electrotechnology, with the participation of German experts from DIN Aerospace Standards Committee. AeroSpace and Defence Industries Association of Europe - Standardization (ASD-STAN) has been declared responsible by the European Committee for Standardization (CEN) for preparing European Standards (EN) for the aerospace sector. The responsible German standardization committee is Working Committee NA 131-04-03 AA "Electrical Connectors" at DIN Standards Committee Aerospace (NL).
