6.1 Intended use. The slip ring assemblies covered by this specification are intended for
use with a nominal 28 Vdc, power, signal, and control network supplied from the vehicle engine
driven electrical system and an audio intercommunication circuit. The slip ring assemblies will
provide electrical connection between circuits of a revolving turret and a fixed structure on a
ground based military vehicles. Class I slip ring assemblies are intended for, but not limited to,
use on the M901 Improved TOW Vehicle (ITV). Class II slip ring assemblies are intended for,
but not limited to, use on the M981 Fire Support Team Vehicle (FISTV). Given that the slip ring
assemblies are made exclusively for military vehicles which operate under extreme climatic
conditions, this item is military unique.
