Reference EN 60169-21:1997
Title Radio-frequency connectors - Part 21: Two types of radio-frequency connectors with inner diameter of outer conductor 9,5 mm (0,374 in) with different versions of screw coupling - Characteristic impendance 50 ohms (types SC-A and SC-B)
Project Number 7439
Abstract/Scope Standardizes the interface and ratings of two versions of a medium size r.f. connector for use with flexible and semirigid cables. The connectors are recommended to be utilized in medium power and low reflection applications up to 11 GHz. The dielectric filled interface is especially beneficial in applications involving severe environmental exposure. Both versions of this connector type are screw coupled versions of the Type C connector. The two types are not intermateable. It is recommended to use only the type SC-B in new installations.
