Connectors for electronic equipment - Product requirements - Part 2-111: Circular connectors - Detail specification for power connectors with M12 screw-locking (IEC 61076-2-111:2017)

This part of IEC 61076-2 specifies 4 to 6-way circular connectors with M12 screw-locking with
current ratings up to 16 A and voltage ratings of 63 V or 630 V, that are typically used for
power supply and power applications in industrial premises. These connectors consist of both
fixed and free connectors either rewireable or non-rewireable, with M12 screw-locking. Male
connectors have round contacts Ø1,0 mm and Ø1,5 mm.
The different codings provided by this document prevent the mating of accordingly coded
male or female connectors to any other similarly sized interfaces, covered by other standards
and the cross-mating between the different codings provided by this document.
NOTE M12 is the dimension of the thread of the screw-locking mechanism of these circular connectors.

Connecteurs pour équipements électriques et électroniques - Exigences de produit - Partie 2-111 : Connecteurs circulaires - Spécification particulière pour les connecteurs d’alimentation à vis M12

IEC 61076-2-111:2017 spécifie les connecteurs circulaires à 4 à 6 pôles à vis M12 avec des courants assignés allant jusqu’à 16 A et des tensions assignées de 63 V ou 630 V, qui sont généralement utilisés pour les applications d’alimentation ou de puissance dans les installations industrielles. Ces connecteurs se composent à la fois d’embases et de fiches, démontables ou non démontables, avec un verrouillage à vis M12. Les connecteurs mâles ont des contacts ronds de Ø 1,0 mm et de Ø 1,5 mm.
Les différents détrompages prévus par le présent document empêchent l’accouplement de connecteurs mâles et femelles équipés de tels détrompeurs avec une quelconque autre interface de taille semblable couverte par d’autres normes, ainsi que l’accouplement croisé entre les différents détrompages prévus par le présent document.
M12 est la dimension du filetage du mécanisme de verrouillage à vis des connecteurs circulaires.
Mots clés: Connecteurs, connecteurs circulaires, M12

Konektorji za elektronsko opremo - Zahteve za izdelek - 2-111. del: Okrogli konektorji - Podrobna specifikacija za močnostne konektorje z vijačnim zaklepanjem M12 (IEC 61076-2-111:2017)

Ta del standarda IEC 61076-2 določa 4- do 6-polne okrogle konektorje z vijačnim zaklepanjem M12, nazivnim tokom do 16 A in nazivno napetostjo 63 V ali 630 V, ki se običajno uporabljajo za potrebe napajanja v industrijskem okolju. Ti konektorji so sestavljeni iz pritrjenih in prostih konektorjev z možnostjo ponovnega ožičenja ali brez ter vijačnim zaklepanjem M12. Moški konektorji imajo okrogle kontakte s premerom 1 mm in 1,5 mm.
Različne označitve, določene v tem dokumentu, preprečujejo stikanje ustrezno označenih moških ali ženskih konektorjev s katerimi koli drugimi podobno velikimi vmesniki, ki so zajeti v drugih standardih, in navzkrižno stikanje med različnimi označitvami, podanimi v tem dokumentu.
OPOMBA: M12 je mera navoja mehanizma z vijačnim zaklepanjem teh okroglih konektorjev.
