Type J Mini Plug Plus Power - KF Flange, Single-Ended

We manufacture these miniature connector Type J thermocouple feedthroughs with power leads to transfer a thermocouple’s EMF through a vacuum chamber wall, and supply power, to a device. Rated for high and ultrahigh vacuum applications (depending on mounting termination).

Type J Thermocouple Feedthroughs Feature:

  • Nickel or copper power conductors
  • Use in high and ultrahigh vacuum applications requiring both power and temperature measurements
  • Feature positive wires made of iron and negative wires made of constanan
  • Temperature range from 0° C to 750° C.
  • Assembly supplied with miniature air-side thermocouple connectors and vacuum-side thermocouple lugs with a #3–48 screw and nut

NOTE: Power leads are not supplied with connectors. Must be purchased separately.

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.
