Pancake or “platter” type slip rings are in a flat disk form with concentric conductor rings to provide a maximum number of conductor rings within a minimum amount of axial length.

Pancake slip rings are custom designed and manufactured by The Sibley Company to meet the exact electrical, mechanical and operating conditions for each specific application.  Slip rings of this type can be supplied as a set consisting of a slip ring and a mating brush block assembly or as fully self contained unit with internal  bearings.  

Pancake slip rings can be supplied from less than 1 inch (25 mm) in diameter to over 4 feet (1225 mm).  Through bore diameters are determined by the ring band width needed to accommodate shafts or other internal center structures.  Electrical channels can be low current signals or high Amp power channels with combinations of both determined by the electrical and mechanical considerations which are subject to constraints of the customers application.
