Abstract

IEC 60393-4:2023 is applicable to single-turn rotary power potentiometers wire-wound technology. Enamelled, cemented, moulded, enclosed. This specification is applicable to rotary potentiometers with nominal dissipation in excess of 10 W, the resistive element of which consists of a wire or a wound tape. All the potentiometers specified by this specification are slider-driven without reduction. Their stroke less than 360° is limited by stops. This document specifies preferred ratings and characteristics and selects from IEC 60393-1, appropriate quality assessment procedures, tests and measuring methods. It provides general performance requirements for this type of potentiometer. This document gives the minimum performance requirements and test severities. Annex A lists the letters and symbols used in the clauses of this document. This edition includes the following significant technical changes with respect to the previous edition: a) the document structure has been organized to follow new sectional specification structure decided in TC 40; b) the information on the assessment level EZ and FZ (zero nonconforming) has been revised.
