IECEx Approved Pressure and Vacuum Feedthroughs
Series WF - Feedthroughs for multiple wires and probes
Series WF feedthroughs can provide an efficient seal without recourse to epoxies or other non-adjustable fixture methods when multiple wires must pass through a pressure boundary.
These assemblies cater for up to 12 bare or insulated wires - sizes from 0.2mm2 (24AWG) to approx. 8.8mm2 (8AWG). Depending on which type of element is required to pass through, a different type of assembly can be specified.
Feedthroughs with power wires can be supplied ready for installation as a complete assembly (wires would be cut to lengths specified by the user). Additionally, protection is provided for these wires through the use of insulators, which are rated 55A @ 600Vdc/850Vac max.
Up to 12 small diameter sensor elements can be passed through a WF feedthrough, which must be electrically isolated from one another.
