Glass-to-Metal Seal Technology - Power Feedthroughs

High current and insulation voltage rating
High burst strength
Low leakage rate (Helium leakage tested)
Wide working temperature range

Sensor Applications

Advantages of our high precision, concentric glass-to-metal sealing process
Superior level of miniaturization
Higher burst strength is achieved due to the decreased glass sealing area
More consistent insulation voltage rating
