  • special case note
    Because both Type R and Type S thermocouples use identical extension grade wires, Type R feedthroughs can also be used for Type S.
  • special case 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.
  • special case note
    Negative polarity conductor(s) are longer on the vacuum side.
