Pancake type slip rings are used in applications where slip ring have limited space in height direction. Pancake slip rings are used in medical, measure, test, print and textile industry.


pancake slip ring is mostly used in small space installation which has no more height room.But normally the the rotation speed is not too fast, like lower than 100RPM.

It is also called a rotary electrical interface, Slip Ring Assemblies, Rotary Connector, Slip Ring Units,. It can improve electromechanical capability, simplify system design, eliminate possible damage while rotation. It’s the key apparatus of various precision rotary worktable, electric test instrument, manufacture and process control instrument.


The PS0028-4S, with 4 circiuts and compact 6mm body thickness, which we call our disk slip ring , pcb slip ring, flatter slip ring, spilt slipring.
