Overview

IEC 61076-2-106:2011 is an international standard provided by the International Electrotechnical Commission (IEC) that specifies product requirements for circular connectors used in electronic equipment. This part of the IEC 61076 series focuses on detailed specifications for M16 x 0,75 circular connectors with screw-locking mechanisms. It covers connectors with degrees of protection IP40 and IP65/67, making them suitable for various industrial and measurement applications where reliable environmental protection is essential.

These circular connectors are designed primarily for industrial process measurement and control systems. They include fixed and free connector types, available as rewireable or non-rewireable variants. The male connectors feature round contacts of either 1.5 mm or 1.0 mm diameter, ensuring reliable electrical performance.

Key Topics

• Connector Types and Styles
  The standard defines multiple styles of fixed and free connectors, differentiated by mounting type (front or rear), contact gender (male or female), and protection level (IP40 or IP65/67). Protective caps and accessories for these connectors are also specified.

• Degree of Protection (IP Rating)
  The IEC 61076-2-106 standard ensures connectors meet IP40 for basic protection against solids and limited ingress, or IP65/67 for robust protection against dust and water, suitable for harsh environments.

• Mechanical and Electrical Characteristics
  Detailed mechanical requirements such as insertion/withdrawal forces, contact retention, vibration and shock resistance are outlined. The electrical characteristics include rated voltage, rated impulse voltage, current-carrying capacity, insulation resistance, and contact resistance values.

• Dimensions and Interface Specifications
  The standard provides comprehensive dimensional data for interface compatibility, including panel cut-out dimensions and pin location for different connector variants.

• Testing and Compliance
  A full test schedule covers preliminary tests, dynamic/climatic conditions, mechanical endurance, electrical load, chemical resistivity, and connection methods to guarantee performance and safety.

Applications

IEC 61076-2-106:2011 connectors are widely used in:

• Industrial Process Measurement and Control
  Their robust IP65/67-rated versions are ideal for factory automation, instrumentation, and control systems exposed to dust, dirt, and moisture.

• Electronic Equipment Connections
  Ensures secure, reliable electrical connections in diverse electronics requiring screw-locking circular connectors with standardized dimensions.

• Harsh Environment Installations
  The IP65/67 variants provide secure connections for outdoor or industrial environments where exposure to contaminants and water is expected.

• Field Wiring and Maintenance
  The availability of rewireable and non-rewireable free connectors supports ease of installation and maintenance in the field.

Related Standards

• IEC 61076-2 Series
  Other parts cover additional circular connector sizes and styles, extending the scope beyond M16 connectors.

• IEC 60529
  Defines the IP (Ingress Protection) rating system referenced extensively in IEC 61076-2-106 for environmental protection requirements.

• IEC 60228
  Specifies standard conductor sizes and properties which may be applicable for cables terminated by connectors.

• Industry-Specific Standards
  Depending on application, connectors conforming to IEC 61076-2-106 may also comply with additional industrial automation or instrumentation requirements.

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.

This International Standard describes circular connectors with IP40 or IP65/67 protection
degree, typically used for industrial process measurement and control. These connectors
consist of fixed and free connectors, either rewireable or non-rewireable, with M16 × 0,75
screw-locking. Male connectors have round contacts ∅ 1,5 mm or ∅ 1,0 mm.
NOTE IEC 60130-9, Edition 3.0 specified connectors with a similar mating interface for radio and associated
sound equipment. User of this standard should be aware that some of the IEC 60130-9 style could be mated to
some connector styles of this standard. However, IEC 60130-9:2011 (Edition 4.0) no longer includes these styles.
