Electrical & Optical Penetrators
We manufacture several lines of penetrators that facilitate a cable assembly/harness to penetrate a bulkhead or instrument package without the use of connectors. Penetrators require all internal electrical connections to be broken and all wiring brought through the penetrating hole to detach the cable assembly.
Penetrators are used in applications in which a waterproof seal needs to be made between a cable and a pressure vessel. This is often accomplished using a connector set, but if there is no requirement to separate the cable from the equipment, a penetrator may be used.

We manufacture several lines of penetrators that facilitate a cable assembly/harness to penetrate a bulkhead or instrument package without the use of connectors. A penetrator generally has fewer seals and may be physically smaller than a connector pair but hard wiring the cable to the equipment may make it less flexible in use than a connector. A connector set, on the other hand, will allow the cable assembly to be removed without disturbing the hardwiring. Penetrator assemblies have an advantage over connector penetrations in that they do not have the extra set of o-ring seals that are present in a connector set. The penetrator is sealed on the high pressure side (HP) of the cable utilizing the same molding procedures and bond areas as would be seen on the back of a cable connecting plug (CCP).
