What is pancake slip ring?

Pancake slip ring is similar to through hole slip ring but specially used for the rotating system with height limit. Also called flat slip ring, flat disc electrical slip ring, platter slip ring, since the shape is similar to platter, rings and brushes contact around the center of the circle. Pancake slip ring components include stator, rotor and contacts, mainly used for transmit precise signals and power or combined with pneumatic and hydraulic media. More electrical power, current and signals circuits can extend broadwise limitless on flat diameter.
Pancake slip rings can be configured in two types, integrated and separated.
Integrated rings type can be designed for solid or through hole rotating system.
Separated rings type is composed of separated rotor and contact brush, can be designed with PCB.
