Description
We can supply you with everything from the smallest to the largest feedthroughs. Applications include: transmitting measurement signals or power/voltage supplies. Our customers use the feedthroughs in vacuum chambers, nuclear technology, radiation measurement, fuel cells, combustion technology, X-ray technology, high-temperature battery technology, chemical process engineering, X-ray inspection, and satellite technology.
- Ceramic diameters: from 1 mm to 300 mm
- Ceramic lengths: from 1 mm to 800 mm
- Total lengths with current conductors: from 1 mm to 1,700 mm
- Voltage: from 1 millivolt to 2.1 million volts
- Current: 1 milliampere to 10,000 amperes
- Ceramic insulator material: Al2O3 96% and 99.7% (other materials upon request). The ceramic insulator can be glazed or unglazed.
- Standard materials for metal, weld sleeve, and conductor: OF-Cu, Ni42 1.3917, KOVAR 1.3981. Other materials such as titanium, tungsten, and stainless steel are available upon request.
- Vacuum tightness: Standard helium leak rate 10-8 mbar L/s, other leak rates are available upon request.
- Operating temperature: -200 to +700 °C as standard, lower or higher temperatures upon request.
- High-pressure feedthroughs are available upon request.
- Multiple feedthroughs are available upon request.
- Gold-plating of contacts is available.
- Conductor design: Solid rod tube with internal or external thread, blind bore, etc., as required.
- Connection technology: The ceramic can be joined actively or passively using a brazing process. Passive soldering with CuAg72 solder is used as standard. Other solders are available upon request.
- We solder both in vacuum and under inert gas.
Of course, we can weld your feedthroughs into any type of flange upon request. The power feedthroughs are UHV (ultra-high vacuum) compatible, with no outgassing. Only metal and ceramic are used, no flux, no plastics.
