scope:

This part of IEC 63093-3 specifies the important dimensions for the mechanical interchangeability of a preferred half pot-core series 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 standard 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 also should 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.
