Slip Ring | 48 circuits | SVTS A 04-U-X-04/44

Electrical and network transmission for compact machine architectures

Servotecnica SVTS A 04-U-X-04/44 IP65 slip ring
The SVTS A 04-U-X-04/44 combines 44 circuits rated at 2 A with 4 circuits rated at 6 A in a compact 25 mm slip ring with IP65 protection. It combines very high connection density, several higher-current channels and protection suited to more demanding industrial environments.

These units are available in many standard configurations from 18 to 56 circuits. Due to their small ring diameter, the SVTS A 04 series grants low peripheral speed between brushes and rings, as well as reduced dynamic imbalance that means very low wear and long life.

SVTS A 04 models offer E1M and E1G options embedding shielded twisted pairs and adapted rings shapes to suit high data rate applications up to 1Gb/s. E1M options has 2 shielded twisted pairs and is suitable for 100 Base-TX applications (Ethernet 100Mb/s, EtherCAT, Profinet, ...), option E1G has 4 shielded twisted pairs to meet 1000 Base-T applications needs. Offering alongside multiple power/signal combinations they are also available in IP51 or IP65 version

Advantages

  • Option : 100 Base-TX or 1000 Base-T channel with RJ45 plug
  • High data rate
  • Gold alloy rings and brushes
  • Low friction torque
  • High lifetime and reliability
  • Compliant to CE and RoHS

Benefits

  • Allows up to 56 electrical connections to be concentrated on a compact IP65-protected rotating axis
  • Avoids increasing the mechanism diameter when a large number of electrical connections is required
  • Maintains high signal density in environments requiring protection against dust and water jets
  • Meets the needs of rotating equipment combining a high I/O count with environmental constraints
