Modular, aluminium-housed PM series for cranes, earth-moving machinery and outdoor applications: PMR Premium, PME Evolution, PMS and PMP.
PMR Premium
The innovative Slip Ring PMR Premium has been studied, designed and manufactured specifically for applications on small truck cranes and earth-moving machinery, which require reduced dimensions combined with high power supply. Built on a unique design studied down to the last detail, PMR Premium combines a reduced diameter with high modularity, blending the benefit of a small footprint with great versatility in combining brushes and rings to the user's needs, while fully preserving mechanical resistance and a high protection degree.
Equipped with cable entries of different sections to fit any type of cable, PMR Premium can also be customised with Ethernet, PROFIBUS and CAN-BUS, Touch System brushes and auxiliary contacts. It can also be coupled to fluidic joints.
- Mixed versions — with rings and brushes up to 100 A
- High protection — protection degree IP65
- Touch System brushes — for better contact continuity
- Optional accessories — sensors, encoders, fluidic joints upon request
PME Evolution
Designed and manufactured for extremely heavy conditions, the Ravioli Slip Ring Type PME Evolution comes with an aluminium bottom and cover, while the central core of the device is made of a special insulating thermoplastic material that combines high modular versatility with a limited height, keeping both the elevated mechanical resistance and the high protection degree intact.
Copper-graphite, silver-graphite or Touch System contact brushes for signals are available; executions range from 6 to 60 rings at 20/50/100 A. Protection degree IP65; optional angular sensors are available upon request.
PME Evolution is a perfect mix of high resistance to mechanical stress, a multiplicity of single and combined versions, reduced height and dimensions, and high voltages.
A large number of optional accessories — encoders, sensors and air passages — are available upon request.
- Modular versions — high versatility thanks to the sections they are made of
- Touch System brushes — also available for versions with contact brushes
- High protection — protection degree IP65
- Mixed versions — with 20 A, 50 A, 100 A rings
- Optional accessories — encoders, sensors and air passages upon request
PMS
The Ravioli Slip Ring Type PMS is designed with an alloy bottom and aluminium cover, guaranteeing 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 at 20 A and 50 A, protection degree IP55. One or more fluidic passages or angular sensors are available upon request.
Thanks to the limited distance of only 5 mm between the rings, PMS is especially useful for outdoor applications where small dimensions and a reduced device height are required.
- Mixed versions — with 20 A and 50 A rings
- Reduced height — of the device
- Protection — protection degree IP55
- Sensors and air passages — available upon request
PMP
The Ravioli Slip Ring Type PMP is manufactured entirely in metal, ensuring 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 at 20 A and 50 A. Protection degree IP42; optional angular sensors are available upon request.
The key features of PMP are the reduced height of the device — thanks to the limited distance of only 5 mm between the rings — and the capability of supporting a high number of passages.
- Rings available — up to 42
- Mixed versions — with 20 A and 50 A rings
- Sensors and air passages — available upon request
