The SVTS C04 is a through-bore slip ring designed to transmit power and electrical signals simultaneously through a continuously rotating axis. Its 25.4 mm through-bore allows a shaft, cables or other mechanical elements to pass through the centre of the slip ring, while its 78 mm outer diameter provides an architecture suitable for integration into industrial machinery.

Depending on configuration, the SVTS C04 can integrate up to 48 circuits and combine power circuits rated up to 15 A with 2 A signal circuits. Its multipoint contact technology helps maintain low electrical contact resistance, low electrical noise and reduced wear without requiring lubrication.

Servotecnica also offers dedicated SVTS C04 configurations for Ethernet transmission: E1M for Fast Ethernet 100Base-T and E1G for Gigabit Ethernet 1000Base-T. These versions allow power, signals and Ethernet communication to be integrated within a single rotary interface.

Thanks to its through-bore architecture and wide range of electrical configurations, the SVTS C04 is particularly suitable for rotary tables, indexing systems, packaging machinery, automated equipment and other applications requiring multiple connections through a continuously rotating axis.

Advantages
