A slip ring capsule can be used in any electromechanical system that requires unrestrained, intermittent or continuous rotation while transferring power and / or data. A slip ring is also called a rotary electrical joint, collector, commutator or swivel. A slip ring can improve system performance by simplifying operations and eliminating damage prone wires.

The AC6438 provides an economical, readily available solution when a compact through-bore configuration is required. This unit provides a 1/2 inch through-bore for routing of hydraulic or pneumatic lines, and a compact 2.1 inch outside diameter and a very short overall length for minimal space applications. The AC6438 slip ring with through bores provides 5 amp circuits in 6, 12, 18 and 24 ring configurations. Similar in design to our very popular AC4598 and AC6200 series, this design features long life, fiber brush contact technology for ultimate performance in many challenging applications.
