What Is a Hermetically Sealed Connector?
A hermetically sealed connector is designed to prevent the intrusion of moisture, dust, and other contaminants from the external environment, thereby protecting electrical circuits and connections.
These connectors utilize specialized cables and terminals to isolate internal circuits from external conditions completely. They are primarily employed in outdoor environments, areas with high humidity, and heavily polluted locations. Typically constructed from highly weather-resistant materials, the bodies of the connectors and their mating parts are covered with materials like rubber, silicone, or plastic, which provide excellent waterproofing and dustproofing properties. This coverage ensures that the internal electrical circuits and terminals are not exposed to moisture and dust, thus guaranteeing reliable connections.
Hermetically sealed connectors are ideal for applications like outdoor lighting, waterproof cameras, automotive sensor connectors, and electronic devices used on aircraft and ships, where they must withstand severe environmental conditions.
