A hermetic connector is a connector equipped with a structure to prevent the intrusion of water, dust, and other contaminants into its interior.
Hermetic connectors are primarily used in outdoor environments and areas with high levels of contamination. The operational principle involves sealing the inside and outside of the connector to prevent intrusion, using components such as gaskets, O-rings, welding, crimping, and sealants. Their features include preventing the intrusion of water and dust, high durability, and reliability, making them suitable for outdoor and contaminated environments.
They are employed in outdoor equipment and facilities, machinery used in heavily polluted environments, and devices requiring waterproofing and dustproofing. Hermetic connectors consist of three components: the connector body, terminals, and cables, each responsible for sealing the interior and exterior and transmitting signals or power.
