FOREWORD
1)
The IEC (International Electrotechnical Commission) is a worldwide organization for standardization
comprising all national electrotechnical committees (IEC National Committees). The object of the IEC is to
promote international cooperation on all questions concerning standardization in the electrical and
electronic fields. To this end and in addition to other activities, the IEC publishes International Standards.
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. The 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 the IEC on technical matters, prepared by technical committees on
which all the National Committees having a special interest therein are represented, express, as nearly as
possible, an international consensus of opinion on the subjects dealt with.
3) They have the form of recommendations for international use published in the form of standards, technical
reports or guides and they are accepted by the National Committees in that sense.
4)
In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
International Standard IEC 1076-4-105 has been prepared by sub-committee 48B:
Connectors, of IEC technical committee 48: Electromechanical components and mech-
anical structures for electronic equipment.
The text of this standard is based on the following documents:
DIS Report on voting
48B/362/DIS
48B/416/RVD
Full information on the voting for the approval of this standard can be found in the repo
rt
on voting indicated in the above table.
Annexes A, B, C and D form an integral part of this standard.
The QC number that appears on the front cover of this publication is the specification
number in the IEC Quality Assessment System for Electronic Components (IECQ).

Section 105: Detail specification for 9 mm circular connector
with 3 to 8 contacts for use in a wide range of applications

1 General data
1.1 Recommended method of mounting
A complete connector consists of a fixed connector and a free connector. The fixed
connector is mounted vertically or at a right angle to the printed circuit board. The free
connector is terminated to a cable consisting of three to eight conductors (shielded or un-
shielded).
1.2 Minimum and maximum number of contacts
The fixed and the free connector have a range of three to eight contacts. Each connector
is keyed to prevent mismating. Examples of contact arrangements are shown in figure 2.
1.3 Rating and characteristics
Wording voltage: 30 V a.c. r.m.s. or d.c.
1 A max.
Current rating:
Insulation resistance: 1 000 MO min.
PL1: 55/100/56

PL3:
Printed board thickness: 1,58 mm (0,062 in)
Contact spacing: Varies with number of contacts.
1.4 Normative references
The following normative documents contain provisions which, through reference in this
text, constitute provisions of this section of IEC 1076-4. At the time of publication,
the editions indicated were valid. All normative documents are subject to revision, and
parties to agreements based on this section of IEC 1076-4 are encouraged to investigate
the possibility of applying the most recent editions of the normative documents indicated
below. Members of IEC and ISO maintain registers of currently valid International
Standards.

Therefore, the clearance and creepage distances are given as operating characteristics.
In practice, reductions in creepage or clearance distances may occur due to the wiring
used and shall duly be taken into account.

3 Test schedule
3.1 General
This test schedule shows all tests and the order in which they shall be carried out as well
as the requirements to be met.
Unless otherwise specified, all tests shall be carried out under standard atmospheric
conditions for testing as specified in IEC 68-1.
Unless otherwise specified, mated sets of connector modules shall be tested. Care shall
be taken to keep a particular combination of connector modules together during the
complete test sequence; i.e., when unmating is necessary for a certain test, the same
connector modules as before shall be mated for the subsequent tests.
In the following, a mated set of connectors is called a "specimen".

- 53 -
1076-4-105 © IEC:1995
When the initial tests have been completed, all specimens are divided up according to the
test groups. Before testing commences, the connector modules must have been stored
for at least 24 h in the non-inserted state under normal climatic conditions for testing as
specified in IEC 68-1.
The test sequence is applicable to all styles of connector modules.
All styles of connector modules shall be fully loaded.
2 to 0,08 mm 2 cross-section.
