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.
