Frequently Asked Questions
What is a shielded high-voltage vacuum feedthrough? Why is grounded shielding essential for vacuum chambers?
A shielded high-voltage vacuum feedthrough is a specialized ceramic-to-metal hermetic connector engineered to transmit electrical power (up to 5kV DC / 3.6A) into vacuum chambers without losing seal integrity. The integrated grounded shield design is essential because it isolates high-voltage electrical fields, suppresses electromagnetic interference (EMI), prevents electrical breakdown, and eliminates leakage risks—ensuring process stability and safety in demanding environments like semiconductor equipment, mass spectrometers, and UHV systems.
How is this high-voltage feedthrough installed? What are its core temperature and pressure limits?
This feedthrough features a weldable 304 stainless steel housing, allowing it to be directly welded onto chamber walls for permanent, ultra-high vacuum (UHV) hermetic sealing. For operating conditions, it withstands maximum pressures up to 1400 PSIG @ 20°C. Its working temperature range is -269°C to 450°C in its plug-free configuration, and -65°C to 165°C when equipped with a plug.
