Benefits & Features Specifications

LPR-2S Series Slip Ring



An electrical slip ring is a device used to transfer power and data from a stationary to a rotating structure. Slip rings can provide continuous or intermittent rotation while transmitting power and data - simplifying operation, improving application performance, and eliminating risk of damage to wiring between movable parts.  A slip ring is also called a rotary electrical interface, collector, swivel or a commutator. A slip ring can improve system performance by simplifying operations and eliminate damage prone to wires dangling from movable joints.


LPR-2S Series slip ring provides routing space for hydraulics, pneumatics or a concentric shaft mount. The LPR-2S adopts advanced fiber brush technology which offers several advantages over conventional slip ring contacts including multiple points of contact per brush bundle, low contact force per fiber and low contact wear rates. In addition, fiber brushes do not require lubrication and produce virtually no wear debris.
