IEC 63093-3:20 20规定了用于感应式接近开关的由铁氧体制成的优选范围的半罐芯的机械互换性的重要尺寸。电感式接近开关的半锅芯也称为PS芯。 本文件的核心尺寸和形状的选择基于包括工业标准的尺寸和形状的理念，或者通过纳入国家标准，或者通过在工业中广泛使用。 IEC 63093的这一部分也可以被认为是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有用的分段规范。根据相关通用规范，它提供了适用于PS型芯的表面不规则性允许限值的指南。本第一版取消并取代了2005年发布的IEC 62323第一版。本版构成技术修订版。 与上一版IEC 62323相比，此版本包括以下重大技术变更: a)添加限制表面不规则性。

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.
