Although we've designed some excellent pancake slip rings, our expertise has shown that a drum design is more cost effective and performs better than a pancake design. A pancake slip ring usually has: greater weight and volume for the same circuits, greater capacitance and crosstalk, greater brush wear and more readily collects wear debris on its vertical axis. However, a pancake offers reduced axial length for the number of circuits. So the decision to use a pancake is usually due to the size and shape of the envelope with which you're work.
