4, 6, 8 or 10 circuit cost-effective slip ring - axial

Michigan Scientific’s S-Series Slip Ring Assemblies are utilized for a variety of applications requiring up to 10 circuit connections. They are designed to mount on the end of a rotating shaft and make electrical connection to strain gages, thermocouples, or other sensors that have been installed on rotating equipment. The slip ring brushes and rings are made of precious metals, which minimize noise and enable the assemblies to be used for low level instrumentation signals. In addition, a high grade stainless steel case provides protection from dust and other contaminants.

These S-Series models are available in 4, 6, 8, and 10 circuit slip ring assemblies. Connections are made through color coded solder terminals located on both the slip ring rotor and slip ring stator. Permanently lubricated bearings eliminate the need for routine cleaning and maintenance. The lightweight and compact design of these slip ring assemblies make them ideal for use in applications where space is limited.


The slip ring can be easily mounted to the end of the shaft with two screws. Sensor's wires can either be linked to the surface or to the inside of the shaft. In the second scenario, a wire groove shall be milled across the end of the shaft or adapter. Connections are made through color coded solder terminals located on the slip ring rotor and a connector on the slip ring stator. Redundant terminals are included to provide back-up connections.

No additional setup is required. The slip ring can be mounted and used in any application. Another great feature is the limited space it takes: 33mm.

Available models

  • Length: de 28 à 41 mm.
  • Wiring connections through soldering terminals. The stator can be equipped with a connector in option.
