Connectors for electrical and electronic equipment - Product requirements - Part 3-123: Rectangular connectors - Detail specification for hybrid connectors for industrial environments, for power supply and fibre optic data transmission, with push-pull locking

IEC 61076-3-123:2019. covers hybrid rectangular connectors with a 3 poles 16 A electric portion for power supply and a duplex fibre optic connector type LC portion for data transmission.
These connectors consist of fixed and free connectors, either rewirable or non-rewirable (for both portions) and use the rectangular push-pull housing described in IEC 61076-3-117 with IP65/IP67 degree of protection, for harsh applications.
The mating dimensions of such housings allow fulfilling the performance class Category I according to IEC 61753-1-3 in regards to the fibre optic portion of the connector with the exception of the operating temperature range which is –25 °C/+70 °C.
The electric portion may have different rated insulation voltages. Male connectors have 3 electric round contacts Ø1,6 mm, with 16 A rated current.
The fibre optic portion provides data transmission by using the common mating configurations for all variants of the type LC duplex fibre optic connectors as defined in IEC 61754-20, for dedicated fibre types and fibre termination technology covered therein.
The different codings provided by this document prevent the mating of accordingly coded male or female connectors to any other similarly sized interfaces covered by other standards and the cross-mating between the different codings provided by this document.
Key words: Rectangular Connectors, Hybrid Connectors, Power Supply and Fiber Optic Data Transmission.

Connecteurs pour équipements électriques et électroniques - Exigences de produit - Partie 3-123: Connecteurs rectangulaires - Spécification particulière relative aux connecteurs hybrides dans des environnements industriels pour l’alimentation et la transmission de données fibronique, avec verrouillage de type pousser-tirer

IEC 61076-3-123:2019 couvre les connecteurs rectangulaires hybrides composés d’une partie électrique 3 pôles, 16 A pour l’alimentation et d’une partie connecteur fibronique duplex de type LC pour la transmission de données. Ces connecteurs sont constitués de fiches et d’embases, démontables ou non démontables (pour les deux parties), et utilisent le boîtier rectangulaire de type «pousser-tirer» décrit dans l’IEC 61076-3-117, offrant le degré de protection IP65/IP67, pour les applications en environnements difficiles. Les dimensions d’accouplement de tels boîtiers permettent de satisfaire à la classe de performances de catégorie I selon l’IEC 61753-1-3 en ce qui concerne la partie fibronique du connecteur, à l’exception de la plage de températures de fonctionnement, qui s’étend de -25 °C à +70 °C.
La partie électrique peut avoir des tensions d’isolement assignées différentes. Les connecteurs mâles possèdent trois contacts électriques cylindriques de 1,6 mm de diamètre, avec un courant assigné de 16 A.
La partie fibronique réalise la transmission de données en utilisant les configurations d’accouplement communes pour toutes les variantes de connecteurs fibroniques duplex de type LC, comme cela est défini dans l’IEC 61754-20, pour les types de fibres dédiés et la technologie de terminaison de fibre couverts ici.
Les différents détrompages prévus par le présent document empêchent l’accouplement de connecteurs mâles et femelles dotés de tels détrompeurs avec une quelconque autre interface de taille semblable couverte par d’autres normes, ainsi que l’accouplement croisé entre les différents détrompages prévus par le présent document.
Mots clés: Connecteurs rectangulaires, connecteurs hybrides, alimentation et la transmission de données fibronique

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 61076-3-123 has been prepared by subcommittee 48B: Electrical

connectors, of IEC technical committee 48: Electrical connectors and mechanical structures for

Part 3-123: Rectangular connectors – Detail specification for hybrid
connectors for industrial environments, for power supply and fibre optic
data transmission, with push-pull locking
1 Scope

This part of IEC 61076 covers hybrid rectangular connectors with a 3 poles 16 A electric portion

for power supply and a duplex fibre optic connector type LC portion for data transmission. These

connectors consist of fixed and free connectors, either rewirable or non-rewirable (for both

portions) and use the rectangular push-pull housing described in IEC 61076-3-117 with

IP65/IP67 degree of protection, for harsh applications. The mating dimensions of such housings

allow fulfilling the performance class Category I according to IEC 61753-1-3 in regards to the

fibre optic portion of the connector with the exception of the operating temperature range which

is –25 °C/+70 °C.

The electric portion may have different rated insulation voltages. Male connectors have

3 electric round contacts Ø1,6 mm, with 16 A rated current.

NOTE Only the phase/neutral contacts are loaded upon current-carrying capacity test of 4.4 and 6.4.3 and electrical

load and temperature test in 7.2.2.6 (DP2) and 7.2.2.12 (KP5)

The fibre optic portion provides data transmission by using the common mating configurations

for all variants of the type LC duplex fibre optic connectors as defined in IEC 61754-20, for

dedicated fibre types and fibre termination technology covered therein.

The different codings provided by this document prevent the mating of accordingly coded male

or female connectors to any other similarly sized interfaces covered by other standards and the

cross-mating between the different codings provided by this document.
