Electrical Feedthroughs for UHV and High Vacuum, compliant with the Sub-miniature D specification. Allectra manufacture and supply <a href="https://shop.allectra.com/products?categories=Sub-Miniature%20D%20Feedthroughs">Sub-D electrical feedthroughs</a> for electrical connections through vacuum walls for High and Ultra High Vacuum applications.
Allectra is a manufacturer and supplier of insulated Kapton wires and accessories for UHV as well as tools for use with plugs and sockets. Help for choosing a suitable wire: - Dipped wire is a good choice, if the parts need no or little movement. These are the cheapest version. Stripping is difficult. - For radiation environment and temperatures above 260°C KAP301 wires are recommended. - If flexibility is required, Multi Strand types should be used. These are the typical wires for connecting sensors, motors etc. Stripping is easy
UHV and High Vacuum Fibre Optic Components. For an increasing number of applications, Optical Fibres are used in vacuum either to get signals out or to bring "light" to the right point into the chamber. The 3 different types of Optical Fibres: • The Step Index Fibres are the thickest Fibres used. They are used for illumination or heat transfer by light and applications such as Spectroscopy. These Fibres have an Outside Diameter of 400 or 600 microns. • The Graded Index Fibres are typically data fibres. They have the advantage that the signal is kept sharper. • The best signal fibres are the Single Mode types. By having a very small diameter (6-9µm), which is much smaller than the wavelength of the light, there is only one optical path available and the signal keeps its shape. Both Graded Index and Single Mode have an Outside Diameter of 125 microns. Allectra offers Feedthroughs and components with all three types.
An ideal component for low current or voltage measurements, where high accuracy and lowest disruption of the signal are required. These are coaxial feedthroughs from Allectra which can be used universally and are specifically for transmitting high frequency signals. Allectra are a manufacturer and supplier of triaxial feedthroughs, a type of coaxial feedthrough, for High and Ultra High Vacuum applications.
