GlassTomer™ Technology with Aluminum Housing
This lightweight, high-voltage hermetic coaxial feedthrough combines a precision-machined aluminum flange with advanced GlassTomer™ sealing technology. Designed for high-voltage and RF (radio frequency) applications, this component ensures exceptional electrical performance while maintaining ultra-low helium leak rates.
The unique aluminum body construction provides a significant weight reduction without compromising structural integrity or hermeticity, making it ideal for airborne, spaceborne, and mission-critical electronic assemblies.
Whether used for coaxial signal lines, power transmission, or hybrid signal-power configurations, this feedthrough guarantees robust performance in harsh environments — including high vacuum, thermal cycling, and vibration-prone settings.
Key Features
Advanced Hermetic Sealing
Utilizes GlasTomer™ hybrid glass-to-metal sealing for ultra-low leak rates: ≤ 1×10⁻⁸ atm·cc/sec (helium).
Lightweight Aluminum Construction
Aerospace-grade aluminum flange offers superior weight savings compared to traditional Kovar or stainless steel designs, without compromising durability.
High Voltage Isolation
