IEC 62246-4 Ed. 1.0 b:2023

This part of IEC 62246 gives additional requirements for the evaluation of functional characteristics on reed switching components operated by magnetic actuator and gives guidance for their implementation in selected applications.

This document specifies test and measurement procedures for the application of reed switch (contact) based magnetic sensors.

NOTE This document can be used in conjunction with specific product standards (e.g. IEC 60947-5-1) applying reed switching with magnetic actuation to provide specific requirements and verification methods.

In case the application of a reed contact magnetic sensor determines additional requirements exceeding those specified in this document, the sensor is evaluated with this application in accordance with the relevant IEC or ISO standard(s) (e.g. IEC 62061 or ISO 13849 series, IEC 60335-1 and relevant parts of the IEC 60335-2 series, IEC 60730-1, IEC 61373, ISO 16750-3).

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).

Information contained in this document is relevant to the application of a magnetic sensor on new installations as well as modifications to existing installations.
