What Are Sealed And Hermetically Sealed Connectors?
Sealed and hermetically sealed connectors are specifically designed to protect against oxidation or corrosion caused by the ingress of moisture or gas. They ensure uninterrupted signal transmission without interference.
How Many Series? What Is Your IP Rating?
Our sealed connector series include N, BNC, TNC, SMA, and adapters.
- Sealed connectors provide protection with an IP68 rating.
- Hermetically sealed connectors offer sealing with a helium leak rate of 1×10⁻⁸ cc/sec, making them ideal for outdoor and harsh environments.
Customization options are also available to meet specific application needs.
Comparison: Sealing Materials
Sealing materials such as O-rings and glass beads are commonly used in connector design.
- Glass bead is an ideal electrical insulating material for hermetic connectors. Its mechanical properties provide high strength and reliable hermetic sealing.
- We utilize a one-piece integrated connector body combined with a glass bead to ensure perfect hermetic sealing, even when unmated.
