Miniature Slip Ring Capsules RK4288

Our product feature for this month are miniature slip ring capsules, (RK4288). Miniature slip ring capsules may be used in any electromechanical project that requires unrestrained, occasional or continuous rotation while transferring power and/or transfer of data.

Each individual assembly includes the rotor, brush blocks, frame, ball bearings and dust cover. This allows for the most compact and smallest weight package for special projects where weight and space requirements are at a premium.

The miniature slip rings can be configured with spacing between rings of 0.015 inch and brush diameters smaller than the diameter of hair! COTS designs are available or we are able to work with you to craft something that meets your unique requirements.
