Low-voltage switchgear and controlgear -- Control circuit devices and switching elements. Proximity switches
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.
