Coaxial feedthroughs
Vacuum components from VACOM
Coaxial feedthroughs offer a wide range of options for transmitting shielded, low-interference electrical signals through the wall of a vacuum system. Other types are also available on request (e.g. Sub-D, Microdot, SMB, SMP, 7/16 DIN, mixed forms).
Versions
SMA
SMA coaxial feedthroughs are the most space-saving solution for transmitting shielded electrical signals through the wall of a vacuum system.
SMA 50 ohm
SMA feedthroughs with 50 ohm impedance are particularly suitable for space-saving, shielded, low-loss transmission of high-frequency signals up to 18 GHz.
SMA 50 ohm, 40 GHz
The special 50 ohm SMA feedthroughs of type K (2.92 mm) are used for shielded, low-loss transmission of high-frequency signals up to 40 GHz.
Type N
Thanks to their medium size and screw connection, type N coaxial feedthroughs stand out for their mechanical robustness and excellent signal integrity.
Type N 50 ohm
Type N coaxial feedthroughs with 50 ohm impedance are ideal for low-loss transmission of RF signals up to 6 GHz and 1.5 kV in vacuum systems.
Type HN 50 ohm
Type HN coaxial feedthroughs with 50 ohm impedance transmit RF signals up to 7 GHz and 7 kV with low loss in vacuum systems, especially short, fast pulses.
BNC
BNC feedthroughs with bayonet connectors are used to transmit moderate voltage and current, shielded, through the wall of a vacuum system.
MHV
MHV feedthroughs with bayonet connectors look confusingly similar to the better-known BNC feedthroughs, but are designed for voltages up to 5 kV DC.
SHV 5 kV
SHV5 feedthroughs (Safe High Voltage 5 kV) provide a touch-safe, shielded high-voltage connection with bayonet coupling for voltages up to 5 kV DC.
SHV 10 kV
SHV10 feedthroughs (Safe High Voltage 10 kV) provide a touch-safe, shielded high-voltage connection with bayonet coupling for voltages up to 10 kV DC.
SHV 20 kV
SHV20 feedthroughs (Safe High Voltage 20 kV) provide a touch-safe, shielded high-voltage connection with bayonet coupling for voltages up to 20 kV DC.
Accessories – coaxial feedthroughs
Air-side and vacuum-side connectors ensure reliable contact with feedthroughs and must be assembled with suitable cables.
BNC 50 OHM
BNC feedthroughs with 50 ohm impedance and a quick-release bayonet connection are used for low-loss transmission of moderate RF signals up to 4 GHz.
Which component fits?
Nominal diameter, flange type, pressure range and material determine the choice. We advise you, put together components from the entire VACOM range and also source special versions.
