MIL-DTL-26482 (formerly MIL-C-26482) describes the general requirements for two series of environment resisting, quick disconnect, miniature, circular electrical connectors (and accessories). Each series includes hermetic receptacles. The two series of connectors are intermateable when using power contacts and are not intermateable when using shielded contacts.
