Multi-Pin Threaded Feedthrough - CF Flange, Single-Ended

These multi-pin instrument feedthroughs have circular threaded connectors on the air-side. Each molybdenum wire conductor is alumina insulated and rated for 500V at a maximum current of 3.5A. The air-side plug is included with the feedthrough but connectors for the vacuum-side wires are not. With CF flanges (air-side cable disconnected) and suitable high temperature vacuum-side connections, these feedthroughs are bakeable to 450°C and are UHV-compatible.

Specifications Table

Vacuum Application	HV or UHV
Metal Seal Temperature Range (Weld Adapter, CF)	-196°C to 450°C
Temperature Max. Ramp Rate	25°C/minute
Air-Side Connector	0°C to 65°C

Note:

The electrical and thermal ratings specified are of safe operating limits determined by various factors including material properties, mechanical design, and the intended operating environment. All electrical ratings are based on operation with one side in dry atmosphere and the other side in vacuum of less than 1 x 10^-4 Torr. All VacuCAD files as well as any dimensions shown or listed in our ordering tables do not include manufacturing tolerances and are provided for reference only.
