These are coaxial feedthroughs from Allectra which can be used universally
and are specifically for transmitting high frequency signals.
Standard BNC Feedthroughs on CF and KF flanges; special 50Ω versions of BNC; Vacuum Ready BNC cables. What does BNC stand for: BNC stands for Bayonet Neill-Concelman. It is a type of coaxial connector that is commonly used in video and audio equipment, scientific instrumentation, and other electronics applications. The BNC connector was named after its two inventors, Paul Neill and Carl Concelman, who developed the connector in the late 1940s while working at Bell Labs. The "bayonet" part of the name refers to the locking mechanism used to secure the connector in place, which involves a twisting motion to lock or release the connector. The BNC connector is known for its durability, ease of use, and ability to transmit high-frequency signals with minimal interference.
Allectra is a manufacturer and supplier of SMA feedthroughs which are connectors for High and Ultra High Vacuum applications. SMA stands for SubMiniature version A. It is a type of coaxial RF connector that is widely used in telecommunications, military and aerospace applications, and other electronic equipment that require high-frequency signals. The SMA connector was developed in the 1960s by Bendix Corporation. The SMA connector is a threaded connector with a 50-ohm impedance and is designed to operate in frequencies up to 18 GHz or even higher, depending on the construction and quality of the connector. The connector is relatively small in size, making it suitable for use in applications where space is limited. The SMA connector is also known for its excellent electrical performance, high reliability, and durability.
Standard 5kV MHV Feedthroughs on CF and KF flanges; special 50Ω versions of MHV;Vacuum Ready MHV Cables MHV stands for "Medium High Voltage". It is a type of electrical connector that is designed to carry high voltage electrical signals in the range of 5 kV to 30 kV. MHV connectors are commonly used in scientific and industrial applications, such as high voltage power supplies, particle accelerators, and x-ray equipment. The MHV connector consists of a cylindrical plug and socket with a threaded coupling mechanism that provides a secure and stable connection. The connector has a center conductor and an outer conductor, which are separated by a dielectric material to prevent arcing and electrical breakdown. The outer conductor is also grounded to prevent electrical interference and reduce the risk of electric shock. The MHV connector is similar to other high voltage connectors, such as SHV (Safe High Voltage) and BNC (Bayonet Neill-Concelman) connectors, but is designed to handle slightly lower voltages. The MHV connector is also compatible with other connectors in the same family, such as the MHV-BNC and MHV-SMA connectors, which are designed to mate with BNC and SMA connectors, respectively.
