Vacuum feedthroughs are critical components used to transfer electrical signals, power, data, and media across the wall of a vacuum chamber while maintaining vacuum integrity. They are widely applied in high vacuum and ultra-high vacuum systems where leak tightness, electrical insulation, and long-term reliability are essential.
Cersol offers a broad range of vacuum feedthrough solutions based on proven ceramic-to-metal sealing technologies, supporting both standard configurations and application-specific customization.
A vacuum feedthrough provides a sealed interface that allows external connections to pass into a vacuum environment without compromising system performance. Depending on the application, feedthroughs may transmit:
1. Electrical and control signals
2. High voltage or high current power
3. RF and high-frequency signals
4. Sensor and thermocouple signals
5. Liquids and process gases
Ceramic feedthroughs are commonly used due to their excellent dielectric strength, thermal stability, and compatibility with demanding vacuum conditions.
