Slip rings can be used in any electromechanical system requiring unrestrained, continuous rotation while transmitting power and/or data from a stationary to a rotating structure.

A slip ring is also called rotary electrical interface, collector, swivel or rotary joint.

slip ring principle

The SRH Series make use of a special technology allowing to get multiple contact points between brushes and ring, low friction torque, reduced mechanical noise and low wear.

Slip Rings can be used in any system requiring the transmission of electrical and/or power signals to an intermittently or continuously rotating shaft. Thanks to the small ring diameter, the SRC Series grants low peripheral speed between brushes and rings, as well as reduced dynamic imbalance what means very low wear. Moreover, the use of noble metals (gold to gold alloy) assures long lasting using life, reduced noises and interferences between circuits, low friction torque.

The above features make the SRC Series specially suited to transmission of critical signals, such as hi frequency signals (video, field buses, etc.), very low currents and voltages (strain gages, thermocouples, measuring equipment etc.), even if versions with up to 6A circuits are available.

Conceived to deliver a flexible, cost-effective, reliable and hi-quality solution, these units are available in many standard configurations and with 6 to 56 circuits. Their compact size allows installation into small systems thus requiring high performances. The SRC Series can easily meet the needs of particular applications and also be customised on demand (connectors, cables length, special cables, number of circuits, etc.).
