High-Performance Vacuum Feedthrough
Vacuum feedthroughs are sealed connection devices designed for high and ultra-high vacuum (UHV) environments. They allow reliable transmission of power, signals, fluids, or motion from atmospheric to vacuum side without compromising system integrity. This product uses advanced ceramic-to-metal sealing for ultra-low leak rates (≤1×10⁻¹⁰ Pa·m³/s), ideal for semiconductor processing, particle accelerators, vacuum coating, surface analysis, and electron microscopy.
Key Features:
- High-Reliability Sealing: Stainless steel flanges (CF/KF/ISO) with high-purity ceramic insulators; UHV-compatible, bakeout up to 450°C.
- Flexible Configuration: Multi-pin options; voltage up to 50kV; current up to 1000A.
- Multiple Types: Power, coaxial (SMA/BNC/SHV), thermocouple, fluid; customizable single/double-ended, grounded/floating.
- Harsh Environment Resistance: Handles high temperature, pressure, and corrosive gases.
- Easy Installation: Standard flanges; compatible with major vacuum systems; quick-plug connectors supported.

FAQ
1. What is the maximum bakeout temperature?
Standard models: up to 450°C. Custom options available up to 600°C—contact us with your requirements.
2. How to choose flange type (CF, KF, or ISO)?
CF for UHV (best sealing); KF for HV (quick install); ISO for larger/medium vacuum. We’ll advise based on your system.
3. Do you support customization?
Yes—pin count, voltage/current, connectors, shielding, materials. Provide specs for a free quote (lead time: 4-8 weeks).
