Low-voltage switchgear and controlgear - Part 5-2: Control circuit devices and switching elements - Proximity switches (IEC 60947-5-2:2007)
This part of IEC 60947 applies to inductive and capacitive proximity switches that sense the presence of metallic and/or non-metallic objects, ultrasonic proximity switches that sense the presence of sound reflecting objects, photoelectric proximity switches that sense the presence of objects and non-mechanical magnetic proximity switches that sense the presence of objects with a magnetic field. These proximity switches are self-contained, have semiconductor switching elements(s) and are intended to be connected to circuits, the rated voltage of which does not exceed 250 V 50 Hz/60 Hz a.c. or 300 V d.c. This Standard is not intended to cover proximity switches with analogue outputs. The object of this standard is to state for proximity switches: - definitions; - classification; - characteristics; - product information; - normal service, mounting and transport conditions; - constructional and performance requirements; - tests to verify rated characteristics.

La présente partie de la CEI 60947 s'applique aux détecteurs de proximité inductifs et capacitifs qui détectent la présence d'objets métalliques et/ou non métalliques, aux détecteurs de proximité ultrasoniques qui détectent la présence d'objets réfléchissants les ultrasons, aux détecteurs de proximité photoélectriques qui détectent la présence d'objets et aux détecteurs de proximité magnétiques non mécaniques qui détectent la présence d'objets avec un champ magnétique. Ces détecteurs de proximité sont des appareils complets, comprennent des éléments de commutation à semi-conducteurs et sont destinés à être connectés à des circuits dont la tension nominale n'excède pas 250 V 50 Hz/60 Hz courant alternatif ou 300 V courant continu. La présente norme n'est pas prévue pour couvrir les détecteurs de proximité analogiques. Par rapport à l'édition précédente, les changements majeurs sont les suivants:-la modification du Tableau 3;-les modifications concernant les essais d'immunité aux creux de tension et aux interruptions de tension, au Tableau 8;-la modification du statut de l'Annexe A, désormais informative.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
