Slip Ring | 54 circuits | SVTS C 08-U-A-18/36

A generous through-bore to free up mechanical design

Servotecnica SVTS C 08-U-A-18/36 IP65 through-bore slip ring
The SVTS C 08-U-A-18/36 is a through-bore slip ring with a 70 mm bore integrating 54 circuits in total, including 36 signal circuits rated at 5 A and 18 power circuits rated at 20 A, with a 155 mm outer diameter and IP65 protection. The slip ring groups signal and power circuits without sacrificing the space through the centre of the axis, reducing the number of separate rotary connections.

The SVTS C08 is a through-bore slip ring designed to transmit a large number of power and signal circuits through a continuously rotating axis. Its 70 mm through-bore allows a shaft, cables or other mechanical elements to pass through the centre of the slip ring, while its 155 mm outer diameter provides a high electrical circuit capacity.

Depending on configuration, the SVTS C08 can combine 20 A power circuits and 5 A signal circuits. Available configurations provide up to 48 power circuits or up to 96 signal circuits, as well as numerous intermediate combinations to meet the requirements of the machine.

Its multipoint contact technology provides multiple contact points between brushes and rings to maintain low electrical contact resistance, reduce electrical noise and limit contact wear. No lubrication is required.

Thanks to its 70 mm through-bore and high circuit capacity, the SVTS C08 is particularly suitable for rotary tables, indexing systems, automated machinery and industrial equipment requiring a large number of power and signal connections between stationary and rotating parts.
