Connectors for electronic equipment - Product requirements - Part 2-109: Circular connectors - Detail specification for connectors with M 12 × 1 screw-locking, for data transmission frequencies up to 500 MHz

IEC 61076-2-109:2014 describes circular connectors with IP 65/IP 67 degree of protection and suitable for data transmission with frequencies up to 500 MHz. Applications include, but are not limited to, vision systems and data acquisition. These connectors consist of fixed and free connectors, either rewireable or non-rewireable, with M 12 x 1 screw-locking. Male connectors have round contacts ∅ 0,6 mm. This standard covers two different types of connectors, denominated X and H, with different contact arrangement, not mutually interchangeable, but with common ratings and purposes.

L'IEC 61076-2-109:2014 décrit des connecteurs circulaires avec un degré de protection IP 65/IP 67 et adaptés à une transmission de données à des fréquences jusqu'à 500 MHz. Les applications incluent, sans toutefois s'y limiter, les systèmes de vision et l'acquisition de données. Ces connecteurs se composent d'embases et de fiches, démontables ou non et sont équipés d'un système à vis M 12 x 1. Les connecteurs mâles possèdent des contacts arrondis de ∅ 0,6 mm. La présente norme couvre deux types différents de connecteurs, désignés X et H, avec différentes dispositions des contacts, non interchangeables, mais avec des caractéristiques assignées et des applications prévues communes.

Standard EN IEC 61076-2-109 opisuje okrogle konektorje s stopnjo zaščite IP 65/IP 67, ki so primerni za prenos podatkov s frekvencami do 500 MHz. Med možne uporabe med drugim spadajo vidni sistemi in pridobivanje podatkov. Ti konektorji so sestavljeni iz pritrjenih in prostih konektorjev z možnostjo ponovnega ožičenja ali brez, z vijačno zaporo M 12 x 1. Moški konektorji imajo okrogle kontakte Ø 0,6 mm. Ta standard obravnava dva različna tipa konektorjev, označena z X in H, z različno razporeditvijo kontaktov, ki nista medsebojno zamenljiva, vendar imata skupne moči in namene.

EN 61076-2-109:2014 - Overview

Standard reference: EN 61076-2-109:2014 (CLC)
This European adoption of IEC 61076-2-109 specifies product requirements for circular connectors with M12 × 1 screw‑locking designed for data transmission frequencies up to 500 MHz. It covers connector forms with IP65/IP67 protection, available as fixed or free (panel and cable) versions and as rewireable or non‑rewireable assemblies. Two non‑interchangeable contact arrangements - type X and type H - are defined; male contacts have a diameter of 0.6 mm. Typical applications include vision systems and data acquisition.

Key topics and technical requirements

• Mechanical and dimensional requirements
  • Interface dimensions for connector types X and H, gauges and polarizing methods.
• Ratings and electrical characteristics
  • Intended for data up to 500 MHz; rated voltages, insulation, contact resistance and current‑carrying capacity are specified.
• Environmental and mechanical performance
  • IP65/IP67 degree of protection, climatic category, vibration and shock endurance, insertion/withdrawal forces, contact retention.
• Safety and marking
  • Marking, safety aspects and insulation coordination requirements.
• Termination and contact details
  • Fixed/free variants, rewireable options and recommended termination methods; male contact Ø 0.6 mm.
• Test requirements
  • Comprehensive test schedule including climatic, mechanical, electrical, chemical resistance and signal integrity tests (referencing IEC 60512‑29‑100 for up to 500 MHz signal tests).

Practical applications

This standard is intended for:

• Industrial Ethernet, machine vision and sensor networks requiring robust, high‑frequency data links.
• Data acquisition systems and embedded controllers where durable, weather‑resistant circular connectors are needed.
• Environments demanding IP65/IP67 protection combined with controlled signal integrity up to 500 MHz.

Who should use this standard

• Connector and cable manufacturers (product design and compliance)
• OEMs and system integrators specifying M12 circular connectors for data transmission
• Test laboratories and certification bodies performing compliance verification
• Purchasing and procurement teams writing technical specifications

Related standards

Relevant cross‑references cited in EN 61076‑2‑109 include:

• IEC/EN 61076‑2 (sectional spec for circular connectors) and IEC/EN 61076‑2‑101 (M12 general)
• IEC/EN 60512 (connector tests and measurements), incl. IEC 60512‑29‑100 for signal integrity
• IEC/EN 60529 (IP code), IEC 60603‑7 series, IEC 61984 (connector safety)

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.
International Standard IEC 61076-2-109 has been prepared by subcommittee 48B:
Connectors, of IEC technical committee 48: Electromechanical components and mechanical
structures for electronic equipment.
This first edition of IEC 61076-2-109 cancels and relaces IEC PAS 61076-2-109, published in

1 Scope
This part of IEC 61076 describes circular connectors with IP 65/IP 67 degree of protection
and suitable for data transmission with frequencies up to 500 MHz. Applications include, but
are not limited to, vision systems and data acquisition. These connectors consist of fixed and
free connectors, either rewireable or non-rewireable, with M12 x 1 screw-locking. Male
connectors have round contacts ∅ 0,6 mm.
This standard covers two different types of connectors, denominated X and H, with different
contact arrangement, not mutually interchangeable, but with common ratings and purposes.
