Electrical Feedthroughs:
Nor-Cal's extensive line of electrical feedthroughs are manufactured from ultra-high vacuum grade materials such as high alumina ceramic insulators, OFHC® copper and nickel conductors, and 304 stainless steel flanges. These robust ceramic to metal feedthroughs have electrical ratings for operation with one side in dry atmosphere while the opposite end is in a stable vacuum. They are used in ultra high vacuum systems with CF flanges or high vacuum systems with NW flanges. CF feedthroughs can be baked to 450°C and NWs to 204°C with maximum system pressure of 1 x 10-4 Torr. Our product line consists of the most commonly required feedthroughs for general vacuum applications. Customs designs or modified standards can readily be supplied.
