Typical applications
Alternatives that meet or exceed these figures
Engineers often come to us with a Servotecnica part number and leave with an alternative that is easier to source, quicker to deliver or a better fit for the machine. These series from our supply network is the closest match on published figures.
Slip rings with dedicated 100M or Gigabit Ethernet channels alongside power and signal circuits, offered in solid-shaft and through-bore forms.
| Published maximum | SVTS A 03 / A 04 Ethernet | Ethernet Slip Ring |
|---|---|---|
| Circuits | 55 | 100 meets or exceeds |
| Current per circuit | 2 A | 30 A meets or exceeds |
| Speed | 500 rpm | 300 rpm |
| Voltage | 240 V | 240 V meets or exceeds |
| Bore | — | 100 mm |
Figures are the highest published for each series and are not always measured the same way. A higher figure is not automatically a better choice: mounting, duty cycle, feedback, connectors and approvals matter too. An engineer will check the fit against your application before recommending anything.
