HD Feedthrough Assemblies

Reliable design that seals 12-60 conductors (24 AWG) in one seal. Can also be customized as desired.

  • Temperature Range: -112˚ F to +250˚ F (-80˚ C to +120˚ C)
  • Vacuum Rating: 5 x 10-6 mmHg @ 68˚ F (20˚ C)
  • Leak Rate: 1 x 10-9 He scc/sec @ 68˚ F (20˚ C)
  • Voltage Rating: 100 Vdc
  • Amperage Rating: 500mA
  •  Feedthrough Pressure Rating @ 68˚ F (20˚ C): 5000 psig (345 bar).

Conax Technologies’ HD Series high density mechanically sealed feedthrough assemblies allow multiple insulated wires to be installed through a single port. These assemblies consist of a stainless steel tube swaged over bundled 24 AWG solid Teflon-insulated thermocouple wire or copper wires. The thermocouple pairs are available with or without junctions.

HD assemblies provide an excellent means to pass numerous thermocouple, RTD and low voltage instrumentation wires through a vessel wall without breaching the wall in multiple locations. HD assemblies can be supplied with or without a Conax Technologies’ “soft seal” gland for pressure/vacuum sealing.
