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.
