A penetrator assembly, for high pressure and/or subsea applications, includes a body. The body includes a first end surface, in operation subject to a pressure of a high pressure environment; a second end surface distanced from the first end surface, which in operation is subject to a pressure of a low pressure environment; at least one connecting passage connecting the first end surface to the second end surface; at least one groove extending from the first end surface towards the second end surface, being distanced from second end surface and surrounding the connecting passage and including an annular opening on the first end surface; and annular lips between a first portion of connecting passage adjacent to the first end surface and the groove, the annular lips in operation being subject to the pressure of the high pressure environment and providing a pressure balance around the first portion of connecting passage.

A set of electromechanical connectors comprises a female structural member having an open end and a male structural member having a tip configured for being received in the open end of the female structural member. A first active connector is fixedly received within one of the male and female structural members. A second active connector is fixedly received within another one of the male and female structural members. Interconnecting the male and female structural members causes the first active connector to come in operative contact with the second active connector. The first and second active connectors are isolated from an environment external to the set of electromechanical connectors when the male and female structural members are interconnected.
