Slip Ring | 41 circuits | SVTS A 04-S-X-00/40-E1M

Electrical and network transmission for compact machine architectures

Servotecnica SVTS A 04-S-X-00/40-E1M Ethernet slip ring
The SVTS A 04-S-X-00/40-E1M combines 40 circuits rated at 2 A with a Fast Ethernet 100Base-TX connection in a compact 25 mm slip ring with IP51 protection. It brings together a large number of electrical connections and network communication at up to 100 Mbit/s in a single rotary interface.

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 rotating axis only 25 mm in diameter
  • Avoids increasing the mechanical assembly diameter as the number of I/O connections grows
  • Allows signal circuits and higher-current circuits to be combined within the same rotary interface
  • Meets the needs of machines requiring a high density of electrical connections in limited space
