BS EN 3645-004-2019 pdf free download.Aerospace series – Connectors, electrical, circular, scoop- proof, triple start threaded coupling, operating temperature 175 °C or 200 °C continuous Part 004: Receptacle, hermetic, square flange mounting – Product standard
This European Standard specifies the characteristics of square flange hermetic receptacles in the family of circular electrical connectors with triple start threaded coupling.
It applies to models in Table 3.
The contacts are unremovable and soldered termination.
For plugs and protective covers, see EN 3645-008, EN 3645-011, EN 3645-012 and EN 3645-006 respectively.
These connectors are derived from and interchangeable with model Y in specification
MIL-DTL-38999/21.
