We supply 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 in order to detach the cable assembly. A connector set, on the other hand, will allow the cable assembly to be removed without disturbing the hardwiring. Penetrator assemblies have one 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).
