Antaira Technologies offers select Ethernet switches with an advanced conformal coating. This coating meets ISO 9223, C1-C5 & ISA 71.04 G3/GX industrial certifications required in toxic environments. Conformally coated devices resist failures caused by corrosion from harsh outdoor applications and harmful substances in the environment.
Protection Against Corrosive Substances
Corrosion is the greatest enemy and threat against electronic components. It causes deterioration of materials due to interactions with the environment that leads to unforeseeable and irreparable damage. Most industrial equipment is not designed with this hazard in mind. Industrial environments may expose electronics to airborne hazardous such as highly corrosive gases, moisture, dust, and debris. These substances create a high risk of failure for critical networking electronics.
Corrosion is a chemical reaction caused primarily by an attack of gaseous contaminants and accelerated by heat and moisture. Corrosive environments may be found in water wastewater plants, mines, and chemical and power plants. And, they are common in many outdoor locations. When field equipment has been operating in ambient air, moisture, and oxygen trigger corrosion on metal surfaces of electronic components. In these industrial environments, gases such as sulfur dioxide emitted from burning fossil fuels and chloride found in water treatment plants will accelerate the corrosive process.
To determine the level of corrosiveness, the International Organization for Standardization (ISO), the American National Standards Institute (ANSI), and the International Society of Automation (ISA) have established a classification system. Antaira’s process for conformal coating meets or exceeds some of the highest classifications for corrosive environments. Corrosion severity level of the environment is classified by four different types of airborne contaminants: liquids, solids, gases, and biological influences.
The corrosivity of an atmosphere is classified based on measurements of pollution categories (i.e. sulfur dioxide and airborne chlorides) and time of wetness. In marine environments, for example, airborne salt crystals can aggravate corrosion on the surface of electronics found near sea water.
Antaira meets or exceeds the Ingress Protection (IP) and conformal coating standards that defends against corrosive environments. Their conformally coated Ethernet switches passed salt spray and gas corrosion tests, making them compliant with the industry standards listed below.
