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

When selecting slip rings, the following important performance specification should be taken into consideration:

• Operating speed rpm
• 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.)
• Maximum voltage and current for the power circuits and signal circuits.
• Type of signal (very important)
• Operating temperature
• IP grade ( sealing requirements)
