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 max. 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.
