IEC 61076-2-115:2023

Overview

IEC 61076-2-115:2023 is an international standard published by the International Electrotechnical Commission (IEC) that specifies detailed requirements for 12-pole shielded circular connectors. These connectors feature a rated current of 2 A, are designed for use with voltages of up to 50 V AC/DC, and provide IP65/IP67 protection through a robust metal housing with push-pull locking mechanisms. This standard is essential for ensuring reliability, performance, and safety of connectors used in various electrical and electronic equipment.

The document outlines key aspects such as dimensional specifications, interface details, technical characteristics, performance criteria, and rigorous testing methods. The combination of shielding, rated current, and protection degree makes these connectors ideal for demanding environments requiring secure and durable electrical connections.

Key Topics

• Connector Type and Configuration
  The standard focuses on 12-pole (12P) shielded circular connectors, detailing both free (male) and fixed (female) connector types suitable for various termination methods.

• Electrical Ratings
  Rated for 2 A current and up to 50 V AC/DC voltage, these connectors cater to low-voltage applications needing reliable power and signal transmission.

• Mechanical and Environmental Protection
  Featuring IP65/IP67 metal housings, these connectors provide dust-tight and water-resistant properties to ensure operational integrity in harsh environmental conditions such as dust ingress or immersion.

• Push-Pull Locking System
  The connectors include a user-friendly push-pull locking mechanism that allows easy mating and unmating while maintaining secure mechanical coupling.

• Performance and Testing
  IEC 61076-2-115:2023 prescribes performance levels, climatic classifications, creepage and clearance requirements, and comprehensive mechanical and electrical testing including vibration, shock, temperature cycling, corrosion, and flammability.

• Dimensional and Interface Specifications
  Detailed dimensions and mounting instructions ensure compatibility and interchangeability, facilitating seamless integration into electrical systems.

• Environmental and Safety Aspects
  The standard addresses material marking, insulation properties, and design considerations to comply with environmental safety and sustainability requirements.

Applications

This standard is highly relevant for industries and applications that require compact, reliable circular connectors with moderate current ratings and enhanced environmental protection. Typical use cases include:

• Industrial Automation
  For connecting sensors, actuators, and control equipment where shielding against electromagnetic interference (EMI) and robust locking is critical.

• Transportation and Railways
  Providing secure electrical connections in challenging operating environments exposed to dust, moisture, and vibration.

• Instrumentation and Measurement Equipment
  Ensuring reliable signal transmission with low current requirements in precision devices.

• Consumer Electronics
  In ruggedized devices where IP65/IP67 protection extends durability and usability.

• Renewable Energy Systems
  Connecting control and monitoring equipment in solar or wind power installations with environmental sealing needs.
