M28840/26CB1CAS1 is the MIL-DTL-28840 plug shipped complete with a straight EMI/RFI environmental backshell. The backshell covers the harness breakout, clamps the shield and terminates it to the shell, so the connector can be used on shipboard cable runs where both moisture sealing and shielded-enclosure continuity are required.
In the M28840/26 number the class letter C follows the slash sheet, then the shell letter, the arrangement digit, the backshell code, the contact style letter and the key position. Shell B is the second shell in the range; because the contact count depends on the insert arrangement, this page publishes the shell and arrangement codes as marked on the release rather than a derived position count.
MIL-DTL-28840 connectors are the US Navy shipboard circular family — the same series appears on Naval Undersea Warfare Center, Pearl Harbor Naval Shipyard and DLA Maritime Supply Chain buys of plugs, receptacles and backshells.
