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.
A PAS is a technical specification not fulfilling the requirements for a standard, but made
available to the public.
IEC PAS 61076-3-126 has been prepared by subcommittee 48B: Electrical connectors, of IEC
technical committee 48: Electrical connectors and mechanical structures for electrical and
electronic equipment.
The text of this PAS is based on the This PAS was approved for
following document: publication by the P-members of the
committee concerned as indicated in
the following document
Draft PAS Report on voting

Following publication of this PAS, which is a pre-standard publication, the technical committee
or subcommittee concerned may transform it into an International Standard.

This PAS shall remain valid for an initial maximum period of 3 years starting from the
publication date. The validity may be extended for a single period up to a maximum of
3 years, at the end of which it shall be published as another type of normative document, or
shall be withdrawn.

Part 3-126: Rectangular connectors – Detail specification for 5 pole
power connectors for industrial environments with push-pull locking

1 Scope
This document covers rectangular IP65/IP67 connectors with 5 poles for electric power supply
up to 16 A. These connectors consist of fixed and free connectors, either rewirable or non-
rewirable (for both portions). It uses the general function principles of the push-pull connector
housing system described in IEC 61076-3-117 with IP65/IP67 degree of protection according
to IEC 60529 for harsh applications.
Male connectors have 5 square 1 mm electric contacts, with 16 A rated current. Connectors
according this document are without breaking capacity COC according to IEC 61984,
therefore they are not intended to be engaged or disengaged in normal use when live or
under load, if not otherwise specified by the manufacturer.

The Detail Quality Specification according to IEC 62197-2-1xx is not applicable.
6.2 Pin assignment and other definitions
See Clause 5.
6.3 Classification into climatic categories
Conditions: IEC 60068-1
Table 1 shows the climatic category.
The lowest and highest temperatures and the duration of the damp heat, steady state
test should be selected from the preferred values stated in 2.2 of IEC 61076-1:2006.
6.4 Electrical characteristics
6.4.1 Creepage and clearance distances
Clearance and creepage distances shall be measured according to IEC 60512-1-2 with the
following additional requirements.
For this connector clearance and creepage distances shall be measured only in mated
position (connector without breaking capacity COC as defined in IEC 61984).
The connector has protection against electric shock by finger safety (IP2X or IPXXB), both in
the mated or unmated condition, after mounting (see also 6.4.2.2 of IEC 61984:2008). For
minimum values for clearance and creepage distances see Clause 5.
6.4.2 Voltage proof
The coordination of creepage and clearance distances has to be performed according
IEC 60664-1.
The connector shall be tested according to the ratings in 6.1 and shall be mounted to the test
panel specified in 5.8.5.
Conditions: IEC 60512-4-1, Test 4a
Standard atmospheric conditions
Mated connectors
For ratings see Table 6 and Table 8.

Application information: The permissible rated voltage depends on the application or specified
safety requirements. Reductions in creepage or clearance distances may occur due to the
printed board or wiring used, and shall duly be taken into account.
