NATIONAL FOREWORD
This Indian Standard (Part 5/See 2) which is identical withIEC6C)947-5-2(1999)
‘Low-voltage switchgear and
controlgear — Part 5-2: Control circuit devices and switching elements — Proximity switches’ issued by the
International Electrotechnical
Commission (lEC) was adopted .by the Bureau of Indian Standards on the
recommendations
of Low-Voltage Switchgear and Controlgear Sectional Committee and approval of the
Electrotechnical Division Council.
In the adopted standard, certain conventions are, however, not identical to those used in Indian Standards.
Attention is particularly drawn to the following:
a) Wherever the words ‘International
‘Indian Standard’; and
Standard’ appear referring to this standard, they should be read as
b) Comma (,) has been used as a decimal marker, while in Indian Standards,
use a point (.) as the decimal marker.
the current
practice is to
Only the English language text has been retained while adopting it in this Indian Standard, and as such the
page numbers have been given afresh here since they are not the same as in IEC Publication.

General
The provisions of the General Rules in part 1 (IEC 60947-1) are applicable to this standard,
where specifically called for. General Rules clauses and subclauses thus applicable, as well as
tables, figures and appendices,
are identified by references to part 1, e.g. subclause 7.1.9.3 of
part 1 or annex C of part 1.
Clauses 1 to 8 contain the general requirements.
proximity switches are given in annex A.
1.1 Scope
Specific
requirements
for the various
types of
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,
— constructional
–
1.2

For the purpose of deciding whether a particular requirement of this standard is complied with, the final value,
observed or calculated, expressing the result of ‘a test or analysis, shall be rounded off in accordance with
IS 2:1960 ‘Rules for rounding off numerical values (revised)’. The number of significant places retained in
the rounded off value should be the same as that of the specified value in this standard.
