60947-5-7  IEC:2003– 5 –INTERNATIONAL ELECTROTECHNICAL COMMISSION____________LOW-VOLTAGE SWITCHGEAR AND CONTROLGEAR –Part 5-7: Control circuit devices and switching elements –Requirements for proximity deviceswith analogue outputFOREWORD1)The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprisingall national electrotechnical committees (IEC National Committees). The object of the IEC is to promoteinternational co-operation on all questions concerning standardization in the electrical and electronic fields. Tothis end and in addition to other activities, the IEC publishes International Standards. Their preparation isentrusted to technical committees; any IEC National Committee interested in the subject dealt with mayparticipate in this preparatory work. International, governmental and non-governmental organizations liaisingwith the IEC also participate in this preparation. The IEC collaborates closely with the InternationalOrganization for Standardization (ISO) in accordance with conditions determined by agreement between thetwo organizations.2)The formal decisions or agreements of the IEC on technical matters express, as nearly as possible, aninternational consensus of opinion on the relevant subjects since each technical committee has representationfrom all interested National Committees.3)The documents produced have the form of recommendations for international use and are published in the formof standards, technical specifications, technical reports or guides and they are accepted by the NationalCommittees in that sense.4)
In order to promote international unification, IEC National Committees undertake to apply IEC InternationalStandards transparently to the maximum extent possible in their national and regional standards. Anydivergence between the IEC Standard and the corresponding national or regional standard shall be clearlyindicated in the latter.5)
The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for anyequipment declared to be in conformity with one of its standards.6)
Attention is drawn to the possibility that some of the elements of this International Standard may be the subjectof patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.International Standard IEC 60947-5-7 has been prepared by subcommittee 17B: Low-voltageswitchgear and controlgear, of IEC technical committee 17: Switchgear and controlgear.This standard should be used in conjunction with IEC 60947-5-2.The text of this standard is based on the following documents:FDISReport on voting17B/1277/FDIS17B/1287/RVDFull information on the voting for the approval of this standard can be found in the report onvoting indicated in the above table.This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.The committee has decided that the contents of this publication will remain unchanged until 2005.At this date, the publication will be•reconfirmed;•withdrawn;•replaced by a revised edition, or•amended.

60947-5-7  IEC:2003– 7 –INTRODUCTIONThis part of IEC 60947 modifies the relevant requirements of IEC 60947-5-2, dealing withthe requirements for proximity switches with semiconductor switching elements, to make themapplicable to proximity devices with analogue output.
