Data Bus Cables & Terminators

Cables Technical Features

  • Twisted shielded MIL-STD-1553B cable.
  • Available in sizes of 6ft, 12 ft, 20 ft.
  • Optional : User definable sizes.
  • High reliability

General Description

The data bus cable consists of two conductors twisted shielded pair (as specified in MIL-STD-1553B) fitted with Trompeter PL-75 (standard miniature TRB Bayonet plug, 3-lug, cable mount or equivalent) on both ends. The data bus cables are available in sizes of 6ft, 12ft and 20ft. In addition to these standard sizes, custom specified size data bus cables are also available (contact ACL for further details).

Terminators Features

  • Low cost.
  • Small size.
  • Rugged construction.
  • High reliability.
    The data bus terminator provides bus terminations as specified in MIL-STD-1553B, when used in conjunction with ACL’s standard Data bus couplers.
