The innovative Slip Ring PMR Premium has been studied, projected and manufactured specifically for applications on small auto cranes and earth-moving machineries, which require reduced dimensions combined to high power supply. Realised with a unique design studied to the last detail, PMR Premium is manufactured to combine a reduced diameter with a high modularity, which allow toperfectly mix the benefit of small space required to high versatility in the combining of brushes and rings, according to the user’s needs, fully preserving the mechanical resistance and the high protection degree.
Equipped with cable entries of different sections, in order to grant the highest adaptability and to perfectly fit any type of cable, PMR Premium can be also personalised with Ethernet, PROFI-BUS and CAN-BUS, Touch System Brushes and auxiliary contacts. They can also be coupled to fluidic joints.

Designed and manufactured to be applied in extremely heavy conditions, Ravioli Slip Ring Type PME Evolution is provided with aluminium bottom and cover, whilst the central core of the device is realised with a special insulating thermoplastic material which combines a high modular versatility together with limited hight of the device, maintaining intact both the elevated mechanical resistance and the high protection degree.
Copper-graphite, silver-graphite or touch system contact brushes for signals are available, executions range from 6 to 60 rings 20/50/100 A. Protection degree IP65, optional angular sensors are available upon request.
Ravioli Slip Rings Type PME Evolution are a perfect mix of heigh resistance to mechanical stress, multiplicity of single and combined versions, reduced hight and dimensions, high voltages.
A large number of optional accessories, encoders, sensors and air passages are available upon request.

Ravioli Slip Ring Type PMS is designed with alloy bottom and aluminium cover which guarantee a strong mechanical resistance and a high protection degree.
Copper-graphite or silver-graphite brushes for signals are available, executions range from 6 to 30 rings 20 A and 50 A, protection degree IP55. One or more fluidic passages or angular sensors are available upon request.
Ravioli Slip Ring Type PMS is extremely useful especially for outdoor applications where small dimensions and reduced hight of the device are required, thanks to the limited distance among the rings of only 5mm.

Ravioli Slip Ring Type PMP is completely manufactured in metal which assures a high mechanical resistance and a good protection degree.
Copper-graphite or silver-graphite brushes for signals are available, executions range from 18 to 42 rings 20 A and 50 A. Protection degree IP42, optional angular sensors are available upon request.
The key features of Ravioli Slip Ring Type PMP are the reduced height of the device – thanks to the limited distance among the rings of only 5mm – and the capability of supporting a high numbers of passages.
