铁氧体磁芯表面不规则尺寸和极限指南第3部分:感应接近开关用铁氧体半槽磁芯

[中文适用范围]： 本部分 IEC 63093-3 规定了用于电感式接近开关的铁氧体半罐形磁芯的重要机械互换性尺寸。电感式接近开关的半罐形磁芯也称为 PS 磁芯。 本文件选择磁芯尺寸和形状的哲学是基于包括那些已成为工业标准或广泛使用的尺寸和形状。 本部分 IEC 63093 也可以被视为一个部分规范，在铁氧体磁芯制造商和客户之间关于表面不规则性的谈判中很有用。它提供了适用于 PS 磁芯的表面不规则性允许限度的指南。 [外文原描述]： 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.
