DESCRIPTION
This standard BS EN IEC 60947-5-2:2020 Low-voltage switchgear and controlgear is classified in these ICS categories:
  • 29.120.40 Switches
  • 29.130.20 Low voltage switchgear and controlgear
IEC 60947-5-2:2019 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.
This fourth edition cancels and replaces the third edition published in 2007 and Amendment 1:2012. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
  • update of the scope;
  • adaptation and update of the construction requirements according to IEC Guide 116 (e.g. material requirements, artificial optical radiation, instruction requirements, hot surface, unattended operation, foreseeable misuse…);
  • modification of the specifications concerning the sensing range and operating distance;
  • new definitions for photoelectric proximity switch type D with background suppression;
  • integration of the requirements and test procedures of photoelectric proximity switch type D with background suppression;
  • update of EMC requirements in Table 9 and Table 10;
  • integration of environmental information requirements and environmental condition by referencing Annexes O, W and Q of IEC 60947-1:2007, IEC 60947-1:2007/AMD1:2010 and IEC 60947-1:2007/AMD2:2014;
  • modification of impulse withstand voltage test (5.3.1.3, 9.3.3.4.5);
  • modification of the references in the (normative) standard body to the (informative) Annex A;
  • major update of Annex A (definitions update, new dimensions and shapes);
  • update of C.9.1.1;
  • update of Annex D in order to consider new connector types and normative references;
  • update of Annex F (additional symbols for photoelectric proximity switches).
