ATEX / IECEx Approved Pressure and Vacuum Feedthroughs

Series HF - High density, insulated wire sealed tube assemblies

A PTFE-lined, stainless steel tube is swaged over multiple, insulated, single-core copper and/or thermocouple-material wires to make a continuous wire, high-density, sealed feedthrough tube. These are used for thermocouples, resistance thermometers and low voltage instrumentation. The sealed tube assembly is usually mounted in a series PF or MF feedthrough. Series HF feedthroughs are manufactured with customer-specified wire lengths.

Epoxies and other sealants are not used in the construction of HF feedthroughs. They are suitable for use where outgassing is not permitted.
  • ATEX / IECEx Approved to Ex II 2 GD, Ex d IIC Gb / Ex e IIC Gb, Ex ta IIIC Da (when sealed with appropriate PF/MF fitting)
  • Saves time and costs as multiple sensor wires pass through one feedthrough
  • Sealed tubes with continuous, multiple, insulated conductors
  • Stainless steel tube (316L) is sealed without potting, epoxies or glues
  • Copper or thermocouple-material wires types J, K, T & N
  • Max. current rating 500mA at 100Vdc
  • Pressure range: Vacuum to 350 bar with low leak rate
  • 4 tube sizes carrying 12, 24, 40 or 60 size 24AWG copper or thermocouple material wires
  • * Dependent on sealant and fitting selected
