    Preface


    This is the harmonized CSA Group and UL standard for Low-voltage switchgear and controlgear – Part 5-2: Control circuit devices and switching elements – Proximity switches. It is the second edition of CSA C22.2 No. 60947-5-2, and the fourth edition of UL 60947-5-2. This edition of CSA C22.2 No. 60947-5-2 supersedes the previous edition published in 2014 as CAN/CSA-C22.2 No. 60947-5-2.


    This harmonized standard is based on IEC Publication 60947-5-2: Edition 3.1, Low-voltage switchgear and controlgear – Part 5-2: Control circuit devices and switching elements – Proximity switches, issued September 2012. IEC 60947-5-2 is copyrighted by the IEC.


    This harmonized standard was prepared by CSA Group and Underwriters Laboratories Inc. (UL). The efforts and support of the Technical Harmonization Committee for Industrial Control Equipment, of the Council on the Harmonization of Electrotechnical Standards of the Nations of the Americas (CANENA), are gratefully acknowledged.


    This standard is considered suitable for use for conformity assessment within the stated scope of the standard.


    This standard was reviewed by the CSA Integrated Committee on Industrial Control, under the jurisdiction of the CSA Technical Committee on Industrial Products and the CSA Strategic Steering Committee on Requirements for Electrical Safety, and has been formally approved by the CSA Technical Committee. This standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.


    General


    The provisions of the general rules in IEC 60947-1 are applicable to this standard, where specifically called for. General rules clauses and subclauses thus applicable, as well as tables, figures and appendices, are identified by references to IEC 60947-1, e.g. subclause 7.1.9.3 of IEC 60947-1 or Annex C of IEC 60947-1.


    Clauses 1 to 8 contain the general requirements. Specific requirements for the various types of proximity switches are given in Annex A.


    1DV D2 Modification of Clause 1 by adding the following:


    Annex DVA defines the specific clauses, tables, and figures in this standard which are to be considered normative, informative, or not applicable. Compliance with the normative clauses, tables, and figures is mandatory; compliance with the informative clauses, tables, and figures is optional.


    1.1 Scope and object


    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.


    1.1DV D2 Modification of 1.1 by adding the following:


    This equipment is intended for use on industrial machinery or mass production industrial equipment as defined and installed in accordance with CSA C22.1, Canadian Electrical Code (CE Code, Part I), and CSA C22.2 No. 301 in Canada, and NFPA 70, National Electrical Code (NEC), and NFPA 79 in the USA.
