Connectors for electrical and electronic equipment - Product requirements - Part 2-114: Circular connectors - Detail specification for connectors with M8 screw- locking with power contacts and signal contacts for data transmission up to 100 MHz

IEC 61076-2-114:2020 describes circular connectors with M8 screw locking typically used for data and power transmissions in industrial applications. These connectors consist of fixed and free connectors that are either rewireable or non-rewireable. Data transmission performance is for Category 5 up to 100 MHz.
Two coded versions, identified as D-coded and P-coded, are provided that differ by their pin size and optionally by number of poles, hence by the function provided for field applications.
Male connectors have round contacts Ø 0,8 mm for D-coded, and Ø 1 mm for P-coded connectors.
The coding provided by this document prevents the mating of accordingly coded male or female connectors to any other similarly sized interfaces covered by other standards.

Overview

IEC 61076-2-114:2020 is an international standard by the IEC that specifies detailed product requirements for circular connectors featuring M8 screw-locking mechanisms. These connectors are designed primarily for electrical and electronic equipment in industrial settings. The standard covers connectors with power contacts and signal contacts supporting data transmission frequencies up to 100 MHz, aligning with Category 5 data communication performance. The specification addresses both rewireable and non-rewireable types of fixed and free connectors, ensuring versatility to meet a broad range of industrial application needs.

Key Topics

• Connector Types and Coding: The standard defines two distinct coding versions identified as D-coded and P-coded. These codings differentiate connector pin sizes-0.8 mm diameter for D-coded male contacts, and 1 mm for P-coded-and optionally vary the number of poles. This coding system prevents mismating between different connector interfaces, enhancing system reliability and safety.
• Mechanical and Electrical Specifications: Detailed mechanical characteristics include M8 screw-locking methods, which provide secure connections avoiding accidental disengagement in industrial environments. Electrical properties such as mutual impedance, insulation resistance, and current-carrying capacity are specified to ensure consistent signal and power quality.
• Data Transmission Capabilities: The connectors conform to data transmission standards up to 100 MHz, supporting Category 5 performance suitable for reliable industrial data communication, including Ethernet and other balanced cabling applications.
• Environmental and Testing Requirements: IEC 61076-2-114 specifies climatic categories, creepage and clearance distances to ensure safety and durability under harsh industrial conditions. It also outlines comprehensive test schedules covering mechanical operation, voltage proof, contact resistance, shock and vibration, and degree of protection (IP code) for connector enclosures.
• Dimensions and Mounting: The standard provides precise dimensional data for both fixed and free connectors, including multiple styles with straight or angled cable outlets. Mounting guidelines and retention force metrics guarantee proper fit and secure installation on panels or equipment.

Applications

IEC 61076-2-114:2020 connectors are critical components in numerous industrial automation and control systems where reliable power delivery and high-speed data transmission are required simultaneously. Typical applications include:

• Industrial Ethernet networks operating up to 100 MHz.
• Machinery and robotics requiring robust, vibration-resistant power and signal connectors.
• Factory automation systems where compact, standardized M8 connectors ensure easy assembly and maintenance.
• Sensors and actuators interfacing with control units using balanced signal cabling with secured connections.
• Harsh environment installations demanding high resistance to mechanical shock, dust, moisture, and temperature variations.

This standard ensures interoperability, safety, and performance adherence for manufacturers, designers, and integrators of electronic devices and electrical equipment using circular connectors with M8 locking.

Related Standards

When implementing IEC 61076-2-114:2020 connectors, consider related IEC standards that define further product requirements and compatibility levels:

• IEC 61076-1: General compatibility and performance levels for circular connectors.
• IEC 60603-7: Connectors used in industrial Ethernet, including RJ45 connectors.
• IEC 61169 Series: Connectors for RF and coaxial applications, where signal integrity is critical.
• IEC 60512: Test methods for electromechanical components and assemblies, providing additional test procedures applicable to M8 connectors.

Adherence to these complementary standards enhances overall system reliability and integration with other industrial components and communication networks.

1 Scope
This part of IEC 61076 describes circular connectors with M8 screw locking typically used for
data and power transmissions in industrial applications. These connectors consist of fixed and
free connectors that are either rewireable or non-rewireable. Data transmission performance
is for Category 5 up to 100 MHz.
Two coded versions, identified as D-coded and P-coded, are provided that differ by their pin
size and optionally by number of poles, hence by the function provided for field applications.
Male connectors have round contacts Ø 0,8 mm for D-coded, and Ø 1 mm for P-coded
connectors.
The coding provided by this document prevents the mating of accordingly coded male or
female connectors to any other similarly sized interfaces covered by other standards.
NOTE M8 is the dimension of the thread of the screw-locking mechanism of these circular connectors.
