Overview
IEC 61076-2-109:2014 is an international standard published by the International Electrotechnical Commission (IEC) that specifies product requirements for circular connectors used in electronic equipment. These connectors feature M 12 x 1 screw-locking mechanisms and support data transmission frequencies up to 500 MHz. Designed for robust industrial applications, these circular connectors provide IP65/IP67 degrees of protection, ensuring reliable performance in harsh environments.
This standard covers two types of connectors, labeled X and H, each with different contact arrangements. Both types share common electrical ratings and intended purposes but are not interchangeable. Male connectors utilize round contacts with a diameter of 0.6 mm, and the range includes fixed and free connectors, which can be either rewireable or non-rewireable.
Key Topics
-
Connector Types X and H: The specification differentiates between two distinct connector configurations to cater to diverse application requirements, with specific interface dimensions and contact placements.
-
M 12 x 1 Screw-Locking Mechanism: Ensures secure and vibration-resistant connections critical for data integrity in industrial environments.
-
Data Transmission up to 500 MHz: Suitable for high-frequency data applications, supporting vision systems, data acquisition, and other demanding use cases.
-
Ingress Protection Ratings: IP65 and IP67 classifications confirm the connectors’ ability to resist dust ingress and withstand immersion in water, making them ideal for rugged applications.
-
Electrical and Mechanical Specifications:
- Rated voltage and impulse voltage values ensuring safe operation.
- Low contact resistance for optimal signal transmission.
- Mechanical endurance to withstand repeated mating cycles.
- Resistance to vibration and shock for reliability.
-
Recommended Termination Methods: Guidelines on contact termination and cable connections for balanced cabling systems, facilitating consistent electrical performance.
-
Compliance Testing and Quality Assurance: Detailed test schedules covering preliminary assessments, dynamic/climatic conditions, mechanical endurance, electrical load, chemical resistivity, connection methods, and electrical transmission requirements.
Applications
IEC 61076-2-109 standard connectors are widely used in industrial and electronic equipment that demands reliable data communication with robust physical and environmental protection. Typical applications include:
