IEC 61076-3-104:2017

Connectors for electrical and electronic equipment - Product requirements - Part 3-104: Detail specification for 8-way, shielded free and fixed connectors for data transmissions with frequencies up to 2 000 MHz

IEC 61076-3-104:2017 establishes uniform specifications, type testing requirements for 8 way, shielded free and fixed connectors for data transmissions with frequencies up to 2 000 MHz, and used as category 7A connectors in class FA cabling systems specified in ISO/IEC 11801-1. It contains all test methods and sequences, severity and preferred values for dimensions and characteristics.
This third edition of IEC 61076-3-104 cancels and replaces the second edition, published in 2006, and constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
- the title has been changed to incorporate transmissions with frequencies up to 2 000 MHz;
- the drawings of some styles have been corrected for clarification;
- Figures 23 and 24 have been updated;
- Figure 3 has been updated to include reference dimensions and dimensional format changes;
- the dimensions of Figure 7 have been updated;
- the type designation and ordering information has been removed for consistency with the most updated sectional specification;
- the test schedule was updated to include appropriate IEC 60512 Test Nos;
- the electrical performance requirements have been revised for 2 GHz level and interchangeability information has been added for performance categories.

Connecteurs pour équipements électriques et électroniques - Exigences de produit - Partie 3-104: Spécification particulière pour les fiches et les embases écrantées à 8 voies pour la transmission de données à des fréquences jusqu'à 2 000 MHz

IEC 61076-3-104:2017 établit des spécifications uniformes, des exigences d’essais de type pour les fiches et les embases écrantées à 8 voies pour la transmission de données à des fréquences jusqu’à 2 000 MHz et utilisées comme des connecteurs de catégorie 7A dans les systèmes de câblage de classe FA spécifiés dans l’ISO/IEC 11801-1. Elle contient toutes les méthodes et séquences d’essai, la sévérité et les valeurs préférentielles pour les dimensions et les caractéristiques.
Cette troisième édition de l'IEC 61076-3-104 annule et remplace la deuxième édition publiée en 2006 dont elle constitue une révision technique.
La présente édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
- le titre a été modifié pour intégrer la transmission à des fréquences jusqu'à 2 000 MHz;
- les dessins de certains modèles ont été corrigés pour être plus clairs;
- les Figures 23 et 24 ont été mises à jour;
- la Figure 3 a été mise à jour pour inclure des dimensions de référence et des modifications de format des dimensions;
- les dimensions de la Figure 7 ont été mises à jour;
- la désignation de type et les informations relatives aux commandes ont été retirées par souci de cohérence avec la version la plus récente de la spécification intermédiaire;
- le programme d'essais a été mis à jour pour inclure les numéros d'essai appropriés de l'IEC 60512;
- les exigences relatives aux performances électriques ont été révisées pour le niveau 2 GHz;
- des informations sur l'interchangeabilité ont été ajoutées pour des catégories de performances.
