A slip ring body for electrically contacting an asynchronous machine includes first and second slip rings rigidly connected to one another, with at least two conductor bars fastened to each of the slip rings. At least one of the slip rings has a recess for passage of the conductor bars of the other slip ring and defining around the recess a first region in which air is at least partially present and which has a magnetic conductivity that is lower than a magnetic conductivity in a second region in which the conductor bars to the one slip ring are fastened, or which second region is embodied for contacting with an energy-transmitting brush. The first and second regions are not made of copper. The recess defines an opening cross-sectional area which is greater than a cross-sectional area of the conductor bars fastened to the one slip ring.

In a slip ring 100, differential signal slip rings 70 are formed using a base substrate 30 where an electrode pattern and a relative permittivity are optimized to transmit a signal by using one differential signal slip ring 70 to one differential signal cable 60a. Consequently, a low voltage differential signal of 0.35V adopted in video signals of 4K resolution can be transmitted while the camera is continuously rotated through 360 degrees.
