Connectors for electrical and electronic equipment - Product requirements - Part 3-122: Detail specification for 8-way, shielded, free and fixed connectors for I/O and data transmission with frequencies up to 500 MHz and current-carrying capacity in industrial environments (IEC 61076-3-122:2021)

This part of IEC 61076 covers 8-way, shielded, free and fixed rectangular connectors for I/O
and data transmission with frequencies up to 500 MHz. It is intended to specify the common
dimensions, mechanical, electrical and environmental characteristics and tests for this family
of connectors.
Connectors complying with this document provide an ingress protection level of IP20; however,
they are particularly suited for industrial environments with a high level of vibration.
NOTE 1 In terms of the MICE system as defined in ISO/IEC 11801-1, the connector matches the requirements of
the M3I1C3E3 levels.
There are two classes of connectors defined in this document, indicated by "class A" and
"class B" which are distinguished by some electrical and mechanical characteristics to meet the
particular sets of requirements of some industrial applications.
NOTE 2 Class A meets the requirements defined in Ed.1 of this document.
NOTE 3 With the two classes A and B, the two codings Type I and II, and the two sets of transmission requirements
according to the component categories Cat 5 and Cat 6A as defined in ISO/IEC 11801-1, this document specifies
2 × 2 × 2 = 8 variants.
All connectors covered by this document feature a current-carrying capacity beyond the
minimum requirement of 0,75 A per pin for an ambient temperature of 60° C as defined in
ISO/IEC 11801-1.
NOTE 4 The current-carrying capacity is given by the current-temperature derating defined in this document and is
dependent on the wire size of the cable attached to the connector.
NOTE 5 With a current-carrying capacity of 0,5 A per pin and with matching the requirement of withstanding the
test current of 2 A for unmating under load as defined in IEC 60512-99-002, the connectors covered by this document
support the highest Power over Ethernet level as defined by IEEE 802.3bt (100 W PoE++ Type 4).

IEC 61076-3-122:2021 couvre les connecteurs rectangulaires à 8 sens, blindés, libres et fixes pour i/o et transmission de données avec des fréquences jusqu’à 500 MHz. Il est destiné à préciser les dimensions communes, les caractéristiques mécaniques, électriques et environnementales et les tests pour cette famille de connecteurs. Les connecteurs qui se conforment à ce document offrent un niveau de protection contre les entrées d’IP20; cependant, ils sont particulièrement adaptés aux environnements industriels avec un niveau élevé de vibration. Il existe deux catégories de connecteurs définies dans ce document, indiquées par « classe A » et « classe B » qui se distinguent par certaines caractéristiques électriques et mécaniques pour répondre aux exigences particulières de certaines applications industrielles. La classe A répond aux exigences définies dans l’Ed.1 de ce document. Avec les deux catégories A et B, les deux codages de type I et II, et les deux ensembles d’exigences de transmission selon les catégories de composants Cat 5 et Cat 6A telles que définies dans ISO/IEC 11801-1, ce document spécifie 2 × 2 × 2 = 8 variantes. Tous les connecteurs couverts par ce document disposent d’une capacité de transport de courant au-delà de l’exigence minimale de 0,75 A par goupille pour une température ambiante de 60°C telle que définie dans ISO/IEC 11801 1. Cette deuxième édition annule et remplace la première édition publiée en 2017. Cette édition constitue une révision technique. Cette édition comprend les changements techniques importants suivants par rapport à l’édition précédente : a) Titre modifié. b) Introduction de deux ensembles d’exigences pour les connecteurs de « classe A » et de « classe B » où la classe A correspond aux exigences définies dans l’édition précédente. c) Définition des nouvelles exigences de performance pour les fréquences jusqu’à 500 MHz en plus des exigences de performance jusqu’à 100 MHz fournies avec l’édition précédente. d) Restructuration pour refléter les points communs et les différences entre le connecteur de type I et le type II. e) Révision des dessins pour clarifier certaines dimensions. e) Le diagramme de dentation a été corrigé pour l’aligner sur la température limite supérieure dans la catégorie climatique, sans réduction des performances pour les applications cibles.

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
