CONNECTORS FOR ELECTRONIC EQUIPMENT –
Part 2-103: Circular connectors – Detail specification for a range of
multipole connectors (type ‘XLR’)
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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
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 61076-2-103 has been prepared by subcommittee 48B: Connectors,
of IEC technical committee 48: Electromechanical components and mechanical structures for
electronic equipment.
The text of this standard is based on the following documents:

1 General information
1.1 Scope
This part of IEC 61076 applies to a range of circular multi-pole connectors with or without
latching device, having a nominal outer shell diameter of 19 mm, with 3 to 7 contacts (type
‘XLR’). Fixed connectors are available in both panel-mounting and printed-board mounting
versions.
These connectors are widely used in professional audio applications.
This part of IEC 61076 establishes uniform specifications, type testing requirements and quality
assessment procedures for a subfamily of circular connectors. It should be used in conjunction
with the applicable sectional specification, see 1.1 of IEC 61076-2.
1.2 Recommended method of mounting
For guidance on the application of connectors in mechanical structures, see IEC 60917-2-2.
Panel-mounted fixed connectors should normally be mounted using screws or bolts rather than
rivets. Printed-board mounted connectors shall be mounted in accordance with the manu-
facturer’s instructions. Cables shall be attached to free connectors in accordance with the
manufacturer’s instructions.
1.3 Number of contacts or contact cavities
This DS deals with connectors with 3 to 7 contacts.
1.4 Ratings and characteristics
Rated voltage: 50 V a.c.
Voltage proof: 1 000 V r.m.s.
Current rating at 70 °C: depends on version (see 4.2.3)
Insulation resistance:
initial: 10 GΩ
after damp heat: 500 MΩ
Climatic category: 25/070/04
Contact spacing: see drawings
1.5 Normative references
The following referenced documents are indispensable for the application of this document. For
dated references, only the edition cited applies. For undated references, the latest edition of
the referenced document (including any amendments) applies.
