AS 3947.5.2-1995

Applies to inductive and capacitive proximity switches that sense the presence of metallic or non-metallic objects, or both; ultrasonic proximity switches that sense the presence of sound reflecting objects and photoelectric proximity switches that sense the presence of objects. This Standard is identical with and has been reproduced from IEC 947-5-2:1992 and Amendment 1:1994.

This International Standard 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 and photoelectric proximity switches that sense the presence of objects.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.
