(Main)Connectors for electrical and electronic equipment - Product requirements - Part 2-117: Detail specification for shielded and unshielded, free and fixed connectors M12 to M40 for power, auxiliary and data transmission with frequencies up to 600 MHz
- Abstract
This part of IEC 61076-2 covers shielded and unshielded, free and fixed circular connectors without breaking capacity (COC) for power, signal and data transmission, and specifies the common dimensions, mechanical, electrical and transmission characteristics and environmental requirements as well as test specifications, respectively.
NOTE 1 As all the connectors described in this document are equipped with shielded data transmission portions, the attribute “shielded” or “unshielded” refers to the additional presence or lack of a shielded connector body.
The connectors described in this document are equipped with an M12, M17, M23 or M40 screw-locking mechanism or a quick-locking mechanism with a size derived from those.
Fixed and rewirable connectors with male or female contacts, mateable with Mxx screw- or quick-locking plugs.
This document provides multiple mating interfaces each of which is associated with a coding preventing the mating of incompatible male and female connectors. The individual codings differ by their numbers of ways, pin layouts and thicknesses, and thus by their power and data transmission capabilities. These codings are referred to as “Type x” where ‘x’ represents an Arabic number.
The connectors described in this document are intended to be used in one-cable automation applications which require various combinations and levels of power up to 600 V AC/ DC and up to 70 A, and either signal or data transmission, or both, with frequencies up to 600 MHz.
NOTE 2 The requirements (or information) described in this document facilitate data transmission through the following Ethernet media systems as defined in IEEE 802.3:
– single-pair Ethernet (10BASE-T1, 100BASE-T1, 1000BASE-T1);
– Fast Ethernet (100BASE-TX);
– Gigabit Ethernet (1000BASE-T);
– 10-gigabit Ethernet (10GBASE-T).

SIST EN IEC 61076-2-117:2026 is a SIST standard for circular connectors for electrical and electronic equipment in M12, M17, M23 and M40 sizes. It specifies shielded and unshielded free and fixed connectors for power, signal and data transmission up to 600 MHz, and it tells manufacturers and users what dimensions, performance characteristics and test methods apply.
What does SIST EN IEC 61076-2-117:2026 specify?
SIST EN IEC 61076-2-117:2026 covers shielded and unshielded circular connectors without breaking capacity (COC) for power, signal and data transmission. It gives the common dimensions, electrical and transmission characteristics, environmental requirements and test specifications needed to design, qualify and compare these connectors.
The document applies to connectors with M12, M17, M23 or M40 screw-locking mechanisms, or quick-locking mechanisms derived from those sizes. It covers fixed and rewirable connectors with male or female contacts, and it includes multiple mating interfaces with coding so that incompatible connectors cannot be mated by mistake.
Clause structure:

- Clause 2 - Normative references
- Clause 3 - Terms and definitions
- Clause 4 - Technical information
- Clause 5 - Dimensional information
- Clause 6 - Characteristics
- Clause 7 - Tests and test schedule
What are the key requirements of SIST EN IEC 61076-2-117:2026?
SIST EN IEC 61076-2-117:2026 combines interface control, electrical ratings, transmission limits, mechanical robustness and qualification testing. In practice, that means the standard is useful both for design approval and for incoming or type testing of connector families.
Coding and compatibility
Clause 5.2 defines the coding system, with Type x codings used to separate mating interfaces that look similar but are not compatible. Clause 4.1 explains the compatibility levels: intermateability is about matching dimensions, while interoperability also requires compliance with the performance requirements and the test sequences in Clause 7.
Why this matters: the coding system prevents accidental mating of the wrong power, signal or data interface, which reduces field errors and mixed-family assembly problems.
Connector styles and dimensions
Clause 5.3 identifies the fixed and free styles for M12, M17, M23 and M40, including straight and right-angled versions, flange mounting, single-hole mounting, rewirable and non-rewirable designs. Clause 5.4 then gives the interface dimensions for each size and coding, with drawings for the mating interfaces and the housing envelope.
Why this matters: manufacturers can check housings, panel cut-outs, locking features and cable-side geometry against the same dimensional basis, and users can verify that two parts from different sources should fit and lock together.
Contact assignments and pin sizes
Clause 6.2 and Tables 36 to 40 define the contact element assignments for the different sizes and Types, including separate data, signal, power, shield and PE functions where applicable. Table 40 gives the pin size families used for power, PE, FE, data and shield contacts.
Why this matters: the contact map tells designers how the connector family separates functions, so they can select the right coding and contact arrangement for a given power or data link.
Climatic and mechanical classification
Clause 6.3 classifies the connectors into climatic categories and defines the performance level taxonomy X, Y and Z. X refers to the climate category, Y to the number of mechanical operations, and Z to shock and vibration severities. If different performance levels are mated, the lower level applies.
Why this matters: system designers need one simple way to compare environmental robustness, especially when mixing connector parts from different performance levels.
Electrical ratings and insulation performance
Clause 6.4 covers voltage information for creepage and clearance, voltage proof, current-carrying capacity, current rating, contact resistance, input-to-output d.c. resistance, insulation resistance and impedance. The document sets the nominal impedance at 100 Ω.
Why this matters: these are the core safety and performance checks for power and data links. They tell the user what electrical stress the connector is intended to withstand, what current the contacts can carry, and whether the connector stays within its resistance and insulation limits.
Transmission performance
Clause 6.5 covers insertion loss, return loss, NEXT, FEXT, TCL, TCTL, transfer impedance, coupling attenuation, PS ANEXT, PS AFEXT and propagation delay. The clause also states that transmission compliance is determined by the test methods in test group FP, and that results are reported as the worst-case outcome across the tested samples.
Why this matters: this is the section that matters most for signal and data integrity. It tells buyers, designers and test labs what must be measured to confirm that the connector will support the intended data transmission performance.
Mechanical strength, locking and protection
Clause 6.6 covers IP degree of protection, mechanical operation, connector coupling devices, insertion and withdrawal forces, polarizing method, vibration and shock. The connectors are specified for IP65/IP67 in the mated and locked position, with IP66, IP68 or other levels by agreement.
Why this matters: these requirements show whether the connector will keep its seal, stay locked, mate with the right orientation and survive repeated use and dynamic stress in the intended installation.
Test programme and qualification flow
Clause 7 defines the specimen handling, preconditioning and test schedule. The full schedule starts with preliminary tests and then separates the specimens into AP, BP, CP, DP, EP, FP, GP and HP groups, with different groups covering climatic stress, endurance, electrical load, chemical resistance, connection methods, transmission, shielding performance and current-carrying capacity.
Why this matters: qualification is not a single test. The document tells laboratories exactly how to prepare specimens, which contacts to measure, how to mount them and which sequence to use for a complete assessment.
What terms does SIST EN IEC 61076-2-117:2026 define?
SIST EN IEC 61076-2-117:2026 uses terms and definitions from IEC 60050-581, IEC 61076-1, IEC 61076-2 and IEC 60512-1.
- Connectors without breaking capacity (COC) - Connectors intended to be used without interrupting current under load, which is why the safety and use conditions need careful control.
- Mating performance level (MPL) - The performance classification used to compare how well connector pairs meet the required mechanical and environmental behavior.
- Protective earth (PE) - The earthing contact used for protection purposes in the connector interface.
- Functional earth (FE) - An earth contact used for functional or screening purposes rather than protective safety grounding.
- Near-end cross talk (NEXT) - Unwanted coupling measured at the same end of the link, important for data pair performance.
- Far-end cross talk (FEXT) - Unwanted coupling measured at the far end of the link, also critical for high-speed data transmission.
- Transverse conversion loss (TCL) - A measure of mode conversion performance, used to judge how well the connector preserves signal balance.
- Transverse conversion transfer loss (TCTL) - A related balance and conversion measure that supports signal integrity evaluation.

connectors M12 to M40 for power, auxiliary and data transmission with
frequencies up to 600 MHz
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) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s), which
may be required to implement this document. However, implementers are cautioned that this may not represent
the latest information, which may be obtained from the patent database available at https://patents.iec.ch. IEC
shall not be held responsible for identifying any or all such patent rights.
IEC 61076-2-117 has been prepared by subcommittee 48B: Electrical connectors, of IEC
technical committee 48: Electrical connectors and mechanical structures for electrical and
electronic equipment. It is an International Standard.
The text of this International Standard is based on the following documents:
