FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 61169-63 has been prepared by subcommittee 46F: RF and
microwave passive components, of IEC technical committee 46: Cables wires, waveguides,

RADIO-FREQUENCY CONNECTORS –
Part 63: Sectional specification – RF coaxial connectors with inner
diameter of outer conductor 6,5 mm (0,256 in) with bayonet lock –
Characteristic impedance 75 Ω (type BNC75)

1 Scope
This part of IEC 61169, which is a sectional specification (SS), provides information and rules
for the preparation of detail specifications (DS) for RF coaxial connectors which can preferably
be used with RF cables 60096 IEC 50-3 of IEC 60096-2. These connector patterns are for low
power, quick connect/disconnect applications using a bayonet type coupling mechanism and
are commonly known as type "BNC" with characteristic impedance 75 Ω.
It describes the interface dimensions for general purpose connectors, dimensional details for
standard test connectors together with gauging information and the mandatory tests selected
from IEC 61169-1, applicable to all DS relating to type BNC connectors with characteristic
impedance 75 Ω.
This document indicates the recommended performance characteristics to be considered
when writing a DS and covers test schedules and inspection requirements.
NOTE The original dimensions are in inches. All undimensioned pictorial configurations are for reference
purposes only.

8 Quality assessment procedures
8.1 General
Subclause 8. 2 provides recommended ratings, performance and test conditions to be
considered when writing a detail specification (DS). They also provide an appropriate schedule
of tests with minimum levels of conformance inspection.
8.2 Ratings and characteristics
This document specifies pin and socket connectors with bayonet lock with a nominal
inner diameter of the outer conductor of 6,5 mm (0,256 in). Cable mounting connectors will
function within specification requirements with 3 mm cables up to a frequency of at
least 18 GHz, and may be used at higher frequencies if a reflection coefficient greater
than 0,1 can be tolerated for straight connectors and 0,13 for right angle styles.
The connectors have a maximum working voltage of 500 V at sea level (125 V at 44 mbar/
20 000 m altitude). Connection to the cable may be made either by crimping or soldering,
depending upon design.
The connector shall be categorised as described in Table 8, and rating and characteristics are
given in Table 9.
– 18 – IEC 61169-63:2020 © IEC 2020
NOTE 1 Patterns for crimping are under consideration. Certain connectors have both barrier and panel seals.
NOTE 2 All voltages specified in this document are RMS values of AC voltages. All test voltages are AC voltages
of 50 Hz to 60 Hz.
NOTE 3 For details of symbols, abbreviations and procedures, see 0.
