DIN EN IEC 60393-4:2024-08

This standard 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. There are no restrictions on the scope of application. Potentiometers are components for use as voltage dividers with three terminals, two of which are connected to the ends of a resistive element and the third to a movable contact that can be moved mechanically along the resistive element.
