The provisions of the general rules in IEC 60947-1 are applicable to this part, where specifically called for. General rules clauses and subclauses thus applicable, as well as tables, figures and annexes, are identified by references to IEC 60947-1, e.g. subclause 7.1.9.3 of IEC 60947-1:2007 + A1:2010 or Annex C of IEC 60947-1:2007 + A1:2010.
Clauses 1 to 8 contain the general requirements. Specific requirements for the various types of proximity switches are given in Annex A.
Integral connectors for plug-in proximity switches are given in Annex D. Various symbols for proximity switches are given in Annex F.
1.1 Scope and Object
This part 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 part 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.
