Radio-frequency connectors - Part 21: Sectional specification for RF connectors with inner diameter of outer conductor 9,5 mm (0,374 in) with screw coupling - Characteristic impedance 50 ohms (Type SC)

This part of IEC 61169, which is a sectional specification (SS), provides information and rules for preparation of detail specification for type SC threaded RF coaxial connectors with 50 Ω characteristic impedance. The connectors are used with flexible and semi-rigid cables. And they 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. It prescribes mating face dimensions, dimensional details, gauging information for general connectors - grade 2 and standard test connectors - grade 0 as well as test schedules and inspection requirements selected from IEC 61169-1, applicable to all detail specifications relating to type SC RF connectors. Type SC interface specified in this specification is equivalent to type SC-B interface in IEC 60169-21: 1985. This specification indicates recommended performance characteristics to be considered when writing a detail specification and it covers test schedules and inspection requirements for assessment levels M and H. NOTE: For this part, original dimensions are in inches. All undimensioned pictorial configurations are for reference purpose only.

Connecteurs pour fréquences radioélectriques – Partie 21: Spécification intermédiaire relatives aux connecteurs RF avec conducteur extérieur de 9,5 mm (0,374 in) de diamètre intérieur à verrouillage à vis – Impédance caractéristique de 50 ohms (Type SC)

IEC 61169-21:2022, qui est une spécification intermédiaire (SS), fournit des informations et des règles pour l’établissement de spécifications particulières (DS) relatives aux connecteurs coaxiaux RF filetés de type SC ayant une impédance caractéristique de 50 Ω. Les connecteurs sont utilisés avec des câbles flexibles et semi-rigides. Leur utilisation est recommandée dans les applications de moyenne puissance et de faible réflexion jusqu’à 11 GHz. L’interface remplie de diélectrique est particulièrement utile dans les applications impliquant une exposition à un environnement sévère. Le présent document spécifie les dimensions de l’interface d’accouplement, les détails dimensionnels, les informations relatives aux calibres pour les connecteurs à usage général (grade 2) et les connecteurs d’essai normalisés (grade 0), ainsi que les programmes d’essais et les exigences de contrôle choisis dans l’IEC 61169-1, applicables à toutes les spécifications particulières relatives aux connecteurs RF de type SC. L’interface de type SC indiquée dans le présent document est équivalente à l’interface de type SC-B de l’IEC 60169-21:1985. Le présent document indique les caractéristiques de performance recommandées à prendre en compte lors de la rédaction d’une spécification particulière, et il couvre les programmes d’essai et les exigences de contrôle pour les niveaux d’assurance M et H.

Radiofrekvenčni konektorji - 21. del: Področna specifikacija za radiofrekvenčne (RF) konektorje z notranjim premerom zunanjega vodnika 9,5 mm (0,374 in) z navojnim spajanjem - Karakteristična impedanca 50 ohm (tip SC) (IEC 61169-21:2022)

Ta del standarda IEC 61169, ki je področna specifikacija (SS), podaja informacije in določa pravila za pripravo podrobnih specifikacij za navojne radiofrekvenčne koaksialne konektorje tipa SC s karakteristično impedanco 50 Ω. Konektorji se uporabljajo s prožnimi in poltrdimi kabli. Priporočljivo jih je uporabljati pri srednji moči in nizkem odboju do 11 GHz. Dielektrični vmesnik je še posebej koristen pri uporabi konektorjev, ki so resno izpostavljeni okolju.
Opisuje mere spojne površine, podrobnosti o merah, informacije o merjenju splošnih konektorjev – tipa 2 in standardnih preskusnih konektorjev – tipa 0 pa tudi razporede preskusov in zahteve pregledov, izbranih iz standarda IEC 61169-1, ki se uporabljajo za vse podrobne specifikacije v zvezi z radiofrekvenčnimi konektorji tipa SC. Vmesnik tipa SC, določen v tej specifikaciji, je enakovreden vmesniku tipa SC-B v standardu IEC 60169-21: 1985.
Ta specifikacija določa priporočene lastnosti, ki jih je treba upoštevati pri sestavljanju podrobne specifikacije, ter zajema urnike preskusov in zahteve za pregled za ravni vrednotenja M in H.
OPOMBA: Izvirne mere v tem delu so podane v palcih. Vse nedimenzionirane slikovne konfiguracije so podane samo v referenčne namene.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations liaising
