Ferrite cores - Guidelines on dimensions and the limits of surface irregularities - Part 3: Half pot-cores made of ferrite for inductive proximity switches

IEC 63093-3:2020 specifies the dimensions that are of importance for mechanical interchangeability for a preferred range of half pot-cores made of ferrite, intended to be used in inductive proximity switches. Half pot-cores for inductive proximity switches are also called PS-cores.
The selection of core sizes and shapes for this document is based on the philosophy of including those sizes and shapes which are industrial standards, either by inclusion in a national standard, or by broad-based use in industry.
This part of IEC 63093 can also be considered as a sectional specification useful in the negotiations between ferrite core manufacturers and customers about surface irregularities. It provides guidelines on the allowable limits of surface irregularities applicable to PS-cores in accordance with the relevant generic specification.
This first edition cancels and replaces the first edition of IEC 62323, published in 2005. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition of IEC 62323:
a) addition of the limits surface irregularities.

Ferritkerne - Richtlinien zu Maßen und Grenzen von Oberflächenbeschädigungen - Teil 3: Ferritschalenkernhälften für induktive Näherungsschalter

Noyaux ferrites - Lignes directrices relatives aux dimensions et limites des irrégularités de surface - Partie 3: Demi-circuits magnétiques en pots en ferrite pour des commutateurs inductifs de proximité

L'IEC 63093-3:2020 spécifie les dimensions importantes pour l'interchangeabilité mécanique d'une gamme préférentielle de demi-circuits magnétiques en pot en ferrite, destinée à être utilisée dans des commutateurs inductifs de proximité. Les demi-circuits magnétiques en pots des commutateurs inductifs de proximité sont également appelés noyaux PS. Le choix des tailles et formes de noyau pour le présent document repose sur la philosophie consistant à introduire les tailles et formes qui correspondent à des normes industrielles, soit dans une norme nationale soit par une utilisation à grande échelle dans le secteur industriel. La présente partie de l'IEC 63093 peut être considérée comme une spécification intermédiaire utile dans les négociations tenues entre les fabricants de noyaux ferrites et les clients concernant les irrégularités de surface. Elle donne les lignes directrices relatives aux limites acceptables des irrégularités de surface applicables aux noyaux PS conformément à la spécification générique correspondante. Cette première édition annule et remplace la première édition de l'IEC 62323 parue en 2005. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente de l'IEC 62323: a) ajout des limites des irrégularités de surface.

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 with the IEC also participate in this preparation. IEC collaborates closely

with the International Organization for Standardization (ISO) in accordance with conditions determined by

agreement between the two organizations.

2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international

consensus of opinion on the relevant subjects since each technical committee has representation from all

interested IEC National Committees.

3) IEC Publications have the form of recommendations for international use and are accepted by IEC National

Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC

Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any

misinterpretation by any end user.

4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

transparently to the maximum extent possible in their national and regional publications. Any divergence

between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in

the latter.
5) IEC itself does not provi
