High Density (HDe) Feedthrough - 1

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. When equipped with a gland, the tube passes through the sealing gland, providing a continuous wire feedthrough. Assemblies configured with a PG gland can accommodate up to 60 conductor wires or 30 thermocouple pairs. An MHM gland can accommodate multiple HD assemblies to seal up to 240 conductors or 120 thermocouple pairs. Assemblies can also be furnished with split glands or MK glands. The stainless steel tube is provided with a 4-1/2” nominal length standard. These feedthroughs are normally furnished with 24 inches of leadwire on each end. Longer lengths may be furnished as required. • Temperature Range: -112° F to +250° F (-80° C to +120° C) • Vacuum Rating: 5 x 10 s mmHg @ 68° F (20° C) • Leak Rate: 1 x 10 sHe scc/sec @ 68° F (20° C) • Voltage Rating: 100 Vdc • Amperage Rating: 500mA • Feedthrough Pressure Rating @ 68° F (20° C): 5000 psig (345 bar). For gland pressure ratings, see the applicable gland section. The Assembly Pressure Rating is limited by the lowest element in the assembly (gland or feedthrough). Conax Technologies can provide numerous options for the management of wires in our sealing assemblies: • Wire Markers with customer nomenclature for easy wire identification of multiple wires • Twisting of wires in pairs or other groupings for easier identification and management • Wire Jackets/Sleeving • Hot Junctions - exposed or encapsulated Please consult your Conax Technologies sales engineer for details.

High Density (HDe) Feedthrough - 3

Datasheet : 100 High Density (HD) Thermocouple Feedthrough for Thermal Validation or Mapping of a Pharmaceutical Freeze Dryer, Sterilizer or Lyophilizer Conax Technologies' High Density (HD) feedthrough assembly is designed to provide a sealed penetration into Freeze Dryers, Sterilizer or Lyophilizer for thermal mapping and operational / performance qualification of the process. The High Density Validation Assembly design has been tested for use in pharmaceutical applications where seal integrity is maintained when thermally cycled to -72°C (-97.6°F). It allows multiple insulated...
