Mini-IO adopted as an International Electrotechnical Commission standard

IEC 61076-3-122 provides miniaturized connector standard for industrial applications in harsh environments

DARMSTADT, Germany – September 18, 2017 – TE Connectivity (TE), a world leader in connectivity and sensors, announced the Mini-IO connector has been adopted as an international standard (IEC 61076-3-122) by the International Electrotechnical Commission (IEC).

IEC 61076-3-122 provides the minimum requirements for a miniaturized connector for industrial applications and thus ensures safety through consistent performance and interoperability. Connector requirements for industrial applications are high as they typically run in harsh environments with high mechanical demands from vibrations and rapid movements, environmental stress through dust and humidity, and possible exposure to radiated electromagnetic fields.

“TE is pleased that with the completion and publication of IEC 61076-3-122, the Mini-IO is the first standardized miniaturized industrial communication connector for an IP20 environment. Beyond its advantages for industrial applications in harsh environments, the small dimensions of the connector enable smaller devices and therefore higher packing densities inside cabinets,” said Guenter Feldmeier, global standardization & consortia leader of TE’s Industrial business unit. “TE Connectivity is pleased that the mini- i/O Standard was based on our technology.”

Referring to its current use in industrial automation systems such as MECHATROLINK and VARAN, Feldmeier adds: “The reliability of the Mini-IO in harsh environments is already demonstrated by industry users. The standard now offers an exciting opportunity to accelerate the adoption by further eco-systems.”

The IEC 61076-3-122 is available for purchase on the IEC website and a preview is available.
