When you have a height restriction, a "pancake" ring - also called a "flat" or "platter" ring - could be the best solution. These slip ring units are based on a disc shaped rotor embedded with concentric grooves carrying the signal and power channels with a brush block assembly mounted over the top to act as the stator.We can build custom versions of this type of ring with anywhere from 4 to 100 channels to include the required center bore size.Contacts are available in precious metal,operating speed has a large bearing on the number of channels and overall. A.)Feature Ultra-thin design,the thickness reached 15 mm min Center bore size can be option Multiple circuit confgurations for power & data signals. Without any maintain.
