Thermo-D™ Thermocouple/Power Feedthroughs

Thermocouple feedthroughs are mixed thermocouple-power contact combinations fitted on one feedthrough assembly constructed with pin arrangements designed to meet IEC 807-2 and DESC 85039 specifications.

Standard configurations include power pins, Chromel® / Alumel® Type-K thermocouple pin pairs, and combinations in a single Subminiature-D shell.  Straight through pins are hermetically sealed and electrically insulated in a stainless steel shell using the latest in glass-ceramic bonding technology.  Ultrahigh (UHV) vacuum cable assemblies with PEEK (polyetheretherketone) connectors and Kapton® insulated wires are available to meet the demands of UHV environments. 

In-vacuum cable assemblies, individual connectors, and other accessories are available from the links below.  Available in both UHV and High Vacuum (HV) configurations. 

Custom thermocouple feedthrough flange and cable assemblies are available on request.

Notes 
  1. Electrical ratings are maximum test values, with feedthrough's vacuum side at ≤ 1x10E-4 Torr. Feedthroughs are intended for instrumentation applications carrying low level signal voltage and current.
  2. PEEK is a polyether ether ketone thermoplastic.
  3. Overall assembly ratings must be adjusted to that of its lowest rated component. For cryogenic service, the lowest recommended temperature is -200°C
  4. Unless designated a 'kit,' connectors and cable assemblies are not included with feedthrough and must be purchased separately.
