IECEx Approved Pressure and Vacuum Feedthroughs

Series WF - Feedthroughs for multiple wires and probes

When multiple wires must pass through a pressure boundary, series WF feedthroughs can provide an efficient seal without recourse to epoxies or other non-adjustable fixture methods.

Different types of these assemblies may be specified according to the type of element required to pass through the feedthrough. Series WF assemblies cater for up to 12 bare or insulated wires – sizes from 24AWG (0.2mm2) to 8AWG (approx. 8.8mm2).

Insulators within WF feedthrough assemblies protect bare wires and provide additional isolation for Kapton® insulated power wires. These are rated 55A @ 600Vdc/850Vac max. Feedthroughs with power wires can be supplied as complete assemblies, ready for installation, with wires cut to specified lengths.

WF feedthroughs can also accommodate up to 12, small diameter sensor elements that must be electrically isolated from each other.
  • IECEx Approved to Ex II 2 GD, Ex d IIC Gb / Ex e IIC Gb, Ex ta IIIC Da
  • Seal on Kapton® insulated copper or thermocouple wires – type WFS
  • Seal on bare wires carrying instrumentation voltages – type WFR
  • Seal on small diameter sheathed sensors, max. 3.2mm dia. – type WFP
  • Pressure range: Vacuum to 700 bar*
  • Temperature range: -60°C to +200°C*
  • Stainless steel body (316L), cap, internal follower and seat
  • Choice of 3 sealant materials
  • Individual wires can be replaced without complete disassembly
  • Reusable fitting – sealant and internal components replaceable
  • * Dependent on sealant and fitting selected
