Low Frequency Slip Ring

  • One piece structure covering both the rotor and stator. Compact structure with small size for convenient installation, mainly for transmission of low current and low frequency signals.
  • The through hole can be realized at the axis center.
  • Superposition of electrical path along the axial direction, adopting gold to gold multi-points contact between the brush and the ring with least friction coefficient, contact resistance and resistance fluctuation.
  • Endurable with long working life.
  • Insulation materials with excellent electric properties are used between adjacent electrical paths.
  • Insulation and shielding treatment well handled on the power and signal channel accordingly.
  • Capable of adapting to various environment such as high temperature, low temperature, impacting, vibration, salt spray, damp heat, water saturation, and etc.
  • Compact design with small size and dimension.
  • Flexible structure, easy and convenient for installation.
  • Low temperature rising during power transmission.
  • With least electromagnetic radiation.
  • Strong anti-interference signal transmission with least loss
  • Strong adaptation to various environment.
  • Wide applications fields.
  • Can be integrated with optical fiber/liquid (gas) rotary joints.
  • Maintenance-free during working life.
Typical Applications:
  • Various Telecommunication Systems.
  • Radar Systems.
  • Fire Control Systems.
  • Precision Detection Machines.
  • Robots.
Customized Options:
  • Outline dimensions.
  • Installation size and installation mode.
  • Materials of housing.
  • Surface treatment.
  • Electrical connection (Wiring and connector).
  • Experiment projects.

Slip rings ensure engineering and design teams no longer require timely – and often costly – workarounds in order to power rotating devices, whether they be motors, military devices or rotating electrical assemblies. Playing a major role in improving mechanical performance, as well as simplifying operations, they have further further eliminated the threat of damaged and hazardous wiring and cable connections in moving joints.

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. 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. We develop, manufacture and market electrical slip rings for power and signal transmission, rotary unions/joints, hybrid rotary transmissions units, fiber optic rotary joints (forj), rotary / linear encoders and RF rotary joints with the collaboration of our partners technologies of industrial applications. Our goal is to match customers requirement of slip rings through high quality products, competitive prices and prompt reliable services. To be a leading company in the field of slip rings, our aim is to fulfill our offers on exact time and perfect quality, by satisfying our customer's demand of slip ring efficiently.

Slip rings handle either power, data or both across a number of rings on which a spring or other loaded contact finger, ring or brush is held in place to pass power as the rings rotate. Power levels range from milliwatts to hundreds of kilowatts dependent on application.
