Glass to Metal Seal Connectors
Overview
Precision glass-to-metal seals provide reliable enclosure protection, reaching target leak rates below 1x10-8 atm cc/s
Utilizing inorganic glass materials completely eliminates outgassing risks common to standard polymer epoxy seals
High-grade stainless steel and Kovar shells deliver exceptional structural rigidity and chemical corrosion resistance
Supporting versatile product formats including circular mil-spec, rectangular d-sub, and high-frequency rf feedthroughs
Engineered to maintain high dielectric strength and insulation stability under high pressure differentials
Capable of surviving severe thermal shocks within standard operating ranges from -55°C to +200°C
Advanced compression and matched sintering technologies optimize mechanical bond integrity based on housing materials
Precision internal impedance management helps minimize vswr variations across high-frequency microwave interfaces
Flexible mounting configurations support effortless enclosure integration via jam nut, solder, or flange designs
Providing comprehensive engineering support from initial technical drawing alignment to finalized sample prototype validation
