DANSK DSF/PREN IEC 62246-4 PDF

This document gives additional requirements on reed switching components and gives guidance for their implementation in selected applications. This part of IEC 62246 applies tests and measurement procedures for the application of reed switch (contact) based magnetic sensors. This document can be used in conjunction with specific product standards (e.g., IEC 60947-5- 1:2016) applying reed switching with magnetic actuation. In case the application of a reed contact magnetic sensor determines additional requirements exceeding those specified in this standard, the sensor should be evaluated with this application in accordance with the relevant IEC/ISO standard(s) (e.g., IEC 62061 or ISO 13849 series, IEC 60335-1 and relevant Parts 2, IEC 60730-1, IEC 61373, ISO 16750, etc.). This document does not apply to: – Sensing or monitoring of the position of elements of interlocking devices for movable guards (see ISO 14119); – Sensing or monitoring of the position of elements of pressure sensitive protective equipment (PSPE, see ISO 13856 series); – Electrical equipment for measurement, control, and laboratory use (see IEC 61010-1); – Aircraft – proximity switches (see ISO 6859-1).
