IEC 60603-7:2020

Connectors for electronic equipment - Part 7: Detail specification for 8-way, unshielded, free and fixed connectors

IEC 60603-7:2020 covers 8-way, unshielded, free and fixed connectors and is intended to specify the common dimensions (interface dimensions), mechanical, electrical and environmental characteristics and tests for the family of IEC 60603-7-x connectors. These connectors are intermateable (according to IEC 61076-1 level 2) and interoperable with other IEC 60603-7 series connectors. This fourth edition cancels and replaces the third edition, published in 2008, its Amendment 1:2011 and its Amendment 2:2019. It constitutes a technical revision. This edition includes the following significant technical change with respect to the previous edition:
- Revised the definitions for intermateability and interoperability; added new definitions.
- Corrected dimension line for dimension AZ2 in Figure 5.
- Corrected dimension line for dimension F1 in Figure A.1.
- Revised the reference to ISO;IEC 11801 to ISO;IEC 11801-1.
- Added lower limiting temperature and upper limiting temperature definitions.
- Revised Table 1 to Table 8 so the column order is Minimum-Nominal-Maximum dimensions (ascending order).
- Corrected Table 7: Climatic category and Upper temperature values to 90 °C (to be consistent with the graph in Figure 10 and Note 1 in Figure 10).
- Revised the wording in 8.2, contact resistance, for clarification.
- Revised Figure 11 and Figure 12 and the wording in the Key below for clarification.
- Removed the sentences under the figure in the Introduction.
- Added Annex E.

Connecteurs pour équipements électroniques - Partie 7: Spécification particulière pour les fiches et les embases non écrantées à 8 voies

L'IEC 60603-7:2020 couvre les connecteurs 8 voies, non couverts, libres et fixes et vise à spécifier les dimensions communes (dimensions d’interface), les caractéristiques mécaniques, électriques et environnementales et les tests pour la famille des connecteurs IEC 60603-7-x. Ces connecteurs sont intermates (selon le niveau 2 de l’IEC 61076-1) et interopérables avec d’autres connecteurs de la série IEC 60603-7. Cette quatrième édition annule et remplace la troisième édition, publiée en 2008, son amendement 1:2011 et son amendement 2:2019. Il s’agit d’une révision technique. Cette édition comprend les changements techniques importants suivants par rapport à l’édition précédente :
- Révision des définitions de l’intermiabilité et de l’interopérabilité; a ajouté de nouvelles définitions.
- Ligne de dimension corrigée pour la dimension AZ2 de la figure 5.
- Ligne de dimension corrigée pour la dimension F1 de la figure A.1.
- Révision de la référence à l’ISO/IEC 11801 à l’ISO/IEC 11801-1.
- Ajout d’une température limite inférieure et de définitions de température limitantes supérieures.
- Tableau 1 révisé au tableau 8 de sorte que l’ordre de colonne est des dimensions minimales-nominales-maximales (ordre croissant).
- Tableau corrigé 7 : Catégorie climatique et valeurs de température supérieures à 90 °C (pour être compatible avec le graphique de la figure 10 et de la note 1 de la figure 10).
- Révision du libellé en 8.2, résistance aux contacts, pour clarification.
- Figure 11 et figure 12 révisées et le libellé de la clé ci-dessous pour clarification.
- Suppression des phrases en vertu de la figure de l’Introduction.
- Ajout de l’annexe E.
