Product details
Keystone Electronics's 7333 redefines Terminals - Solder Lug Connectors technology for ultra-high vacuum (UHV) applications. This all-metal sealed connector maintains 10^-11 torr vacuum integrity while providing reliable electrical feedthroughs. The 7333 is indispensable for particle accelerators, surface science instruments, and semiconductor processing equipment.The Long Stem, Shaped design employs ceramic-to-metal sealing technology, achieving helium leak rates below 1 10^-11 cc/sec at bakeout temperatures of 450 C.Utilizing Smooth Edge construction, these connectors provide 100kV DC isolation in UHV environments while maintaining capacitance below 1pF per contact.Available in 8 Stud variants, these feedthroughs handle currents from femtoampere ion detection to 100A magnet power supplies.Precision 0.093" (2.36mm) machining ensures particle-free operation in Class 1 cleanroom environments, with surface roughness <0.1 m Ra.Flat configuration allows for in-situ replacement without breaking vacuum, using proprietary flange sealing technology.With 0.875" (22.23mm) dimensions optimized for compact UHV chambers, these connectors minimize shadowing in molecular beam epitaxy systems.Brass selection prevents outgassing with total mass loss <0.01% when baked at 250 C for 24 hours.The Tin surface treatment maintains stable contact resistance after 100 thermal cycles between 77K and 700K.
