Mini Compact Slip Ring

  • Our Mini Compact Slip Ring uses casting or injection molding process to be produced with compact and mini size. It is mainly applied for transmitting low current and various LF (low frequency) and MF (medium/intermediate frequency) signals.
  • The slip ring adopts V shape design, while the brush adopts ^ single wire.
  • Both the rotor and the stator are molded as integrated structure without any disassembled parts.
  • Its concentricity can realize up to 0.02mm.
  • The through hole can be realized at the center.
  • Support transmission of up to 300 electric channels simultaneously.
  • The maximum current can be up to 20A.
  • Gold to gold contacts, with advantages of lowest contact resistance and smallest coefficient of friction to realize excellent endurance and low fluctuation of resistance and friction.
  • Very small size and dimension.
  • Lowest rotary torque.
  • Easy and convenient installation.
  • High reliability with very least transmission loss.
  • Compatible with transmission of Gigabit Ethernet signals.
  • Compatible with 1080P UHDV signals.
  • Can be integrated with optical fiber rotary joints.
  • Fast delivery time
  • Wide applications.
Typical Applications:
  • Simulators.
  • Unmanned aerial vehicles (UAV).
  • Various communication system.
  • Precision test machines.
  • Robots.
Customized Options:
  • Outline dimensions.
  • Installation size and installation mode.
  • Materials of housing.
  • Surface treatment.
  • Wiring as well as the specification of the wire and cable.
  • Experiment projects.

China TrueSci industrial slip rings provide the solution to transmit electric power and electrical signals from stationary to rotating units in all types of machines like radar system, antenna dishes, revolving cranes, rotating purifiers in sewage or water treatment facilities, carrousels, manipulators, wrapping machines, theatre stages, wind turbines as well as in cable reels. Our fully developed and versatile standard program facilitates to assemble slip ring assemblies with any number of poles. Current ratings up to 1200 A and voltages up to 24 kV are possible. The range in size for the slip ring assemblies starts with 30 mm up to 360 mm diameter and lined up to 100-poles. Slip ring assemblies can be supplied either as open, “non-enclosed” types for special customer adaptations, or totally enclosed with high impact plastic or galvanised steel housing even for hazardous locations. Additional rotating couplings are available for fluids or gases and fiber optic swivels can be integrated.

Our high-performance slip rings are designed for use in a wide range of high-end OEM applications. We pride ourselves in our ability to provide the right solution for the right application of slip rings.

Slip ring systems can be found in many electrical machines. Thanks to their robust construction, they ensure the functionality of entire machine systems. In addition, we offer optic fibre rotary joints for the contact-free transmission of high data rates.
