Product Name Notes
8 Pin Instrumentation Feedthrough 8 Pin Instrumentation Feedthroughs are normally used for transmitting signal voltages and currents. Process control in surface analysis, electron microscopy and electron beam evaporation are typical applications.
BNC Electrical Feedthrough, Coaxial BNC electrical feedthroughs are consist of two concentric conductor paths which are separated and insulated with high-purity alumina ceramic. These are single-ended grounded shield feedthroughs.
Dual Liquid Nitrogen Feedthrough Dual liquid nitrogen feedthroughs are constructed with dual coaxial tube geometries. This thermal barrier effectively reduces condensation and ice buildup on the atmosphere side of the feedthrough around the mounting...
Heavy Duty Linear Motion Feedthrough
Linear Vacuum Feedthrough
Pneumatic Linear Motion Feedthrough
Linear motion feedthroughs are standard positioning devices used when no rotational movement is required. These feedthroughs are actuated pneumatically, push-pull or rotationally.
Coaxial Magnetic Linear/Rotary Vacuum Feedthrough
Diffferentially Pumped Linear/Rotary Vacuum Feedthrough
Magnetic Linear/Rotary Vacuum Feedthrough
Precision Linear/Rotary Vacuum Feedthrough
Linear rotary feedthroughs are offered in magnetically coupled, bellows sealed and differentially pumped, o-ring sealed versions. These feedthroughs are normally manually actuated. Typically these feedthroughs are used for sample introduction...
Dual Liquid Feedthrough
Single Liquid Feedthrough
Liquid feedthroughs are a cost-effective and reliable way to introduce water into a vacuum system. The .035" single wall construction is designed for the transport of water as a cooling...
Medium Current Copper Feedthrough Medium current copper feedthroughs transmit either high voltage, high current or a combination of both. They are used for sample heating, in-vacuum coating, electron beam evaporation, sputtering, etc. High-purity, high...
Medium Current Nickel Feedthrough Medium Current Nickel Feedthroughs are similar to Medium Current Copper Feedthroughs with the exception of utilizing a nickel conductor in processes and environments which would otherwise attack copper.
MHV Coaxial Feedthrough MHV Coaxial Feedthroughs are similar to BNC Feedthroughs, with the exception to voltage ratings. MHV feedthroughs have a significantly higher voltage rating than BNC feedthroughs, and their electrical ratings are...
1" Bolt Crystal Feedthrough, Microdot-to-BNC
CF Crystal Feedthrough, Microdot-to-BNC
Crystal Feedthrough, 1" Bolt
Nor-Cal Products offers a wide range of Crystal Feedthroughs designed to accommodate a variety of deposition systems. These feedthoughs provide the atmosphere to vacuum connection between the crystal sensor and...
Motorized Rare Earth Magnetic Rotary Vacuum Feedthrough
Precision Rotary Vacuum Feedthrough
Nor-Cal rotary motion feedthroughs are frequently bolted to XYZ manipulators. They are used for applications such as shutter actuation, or in cases where precise angular orientation is required. Construction methods...
Single Liquid Nitrogen Feedthrough Single liquid nitrogen feedthroughs are constructed with single coaxial tube geometries. This thermal barrier effectively reduces condensation and ice buildup on the atmosphere side of the feedthrough around the mounting...
Single Water Cooled High Current Feedthrough Single Water Cooled High Current Feedthrough features a single hollow copper conductor intended for high amperage applications. These feedthroughs should be used in closed loop, grounded systems with deionized water.
Single High Current Feedthrough The Single High Current Feedthrough features a single copper conductor intended for high amperage applications.
Thermocouple Feedthroughs Thermocouple feedthroughs carry instrumentation signals while providing electrical isolation and hermatic sealing. They are leak free in high and ultra high vacuum environments and are composed of only inorganic materials.
Watercooled Medium Current Copper Feedthrough These watercooled electrical feedthroughs transmit power and coolants simultaneously. They will conconduct higher current loads than solid rod conductors of equal size when properly cooled. System should be grounded for...
