What important technical data should be provided when choosing slip rings?

How to choosing the right slip ring?When selecting slip rings, the following important performance specification should be taken into consideration:
1. Operating speed rpm
2.Circuits, signal rings (Circuit, ring and way are all synonymous. If there is a return path or ground then it is a separate circuit. In some slip rings a circuit can be used either way and is counted only once.)
3. Maximum voltage and current for the power circuits and signal circuits.
4. Type of signal (very important)
5. Operating temperature
6. IP grade ( sealing requirements)
