1.  Why are the slip rings selected?
In electric design, when the machine part needs 360unrestrained continuous rotation, the leads should be connected to the rotation part, then the electric engineers will meet the problems of leads wraping. At this time, they need an electrical rotary joint, which is generally called slip rings for the rotation and transmission of power and/or data. 
 
2.  What are the configuration choices of slip rings?
Slip ring configuration choices include drum type or pancake type. In drum type slip rings each ring lies along the drum axis, like threads on a bolt, such as our SRC, FSH, FST series products. In pancake configuration the rings are concentric, like grooves on a phonograph record, such as our SRP series products. At present, majority of the customers choose the drum type slip rings. Only if receive high limits, they will then select the pancake type. 
 
3. What are the configuration choices of drum type slip rings?
According to the installment requirements, we will generally provide the bearing type, and the through-bore hole type.
A. The customers who are familiar with slip rings can select the appropriate models according to the catalogs supplied. If the model you need is not contained in the catalogs, please offer us your technical requirements, and our engineers will design for you specially.
B. The customers who use slip ring for the first time can contact our engineers, and they will solve your questions. 
 
 
4. Which part is rotor or stator in slip ring?
Generally speaking, the circuit part is rotor, and the brush block part is stator. The rotation of a slip ring is bi-directional, and there is no differences whether the circuit or the brush block rotates. As for which part is used as rotor, it is determined by the ways of the installment. 
 
5. 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:
A. Operating speed rpm
B. Installation Type
C. 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.)
D. Maximum voltage and current for the power circuits and signal circuits.
E. Type of signal (very important)
F. Operating temperature
G. IP grade ( sealing requirement)

6. We need slip rings which can transmit both power and signal. Can you provide slip rings like this?
You can see from the catalogs that many of our products can realize the combination of power and signal. 
 
7. The configuration of precise slip ring is compact, do you have any measures for signal atni-jamming?
Precise slip ring is a component with dense leads in a small space. Various signals are concentrated in the slip ring, so effect of mutual inductance and mutual toleration will be great. Because the contact part of brush and circuit cannot be shielded, the coupling capacitance will be extremely serious.  
 
8. At present, there are quite many types of signals, and the requirements are more complex, how many types of signals can be transmitted by your slip ring?
Our slip rings can transmit all  typical middle and low frequency signals, bus-mastering signals, etc.
Such as Data Bus, Can-Bus, Profibus, RS422, RS485, PLC Control, Digital/Simulate Video, Digital Audio, Ethernet, Signals of Temperature etc.
 
9. We need one or two circuits which can transmit high frequency signals in the slip ring, can you produce a slip ring like that?
Yes, we can do it. We have already applied the equipments to radar successfully. If you have details requirements, please contact our engineers, and we will review and provide prosposal to you. 
 
10.Can you offer slip rings which can transmit signals with high speed and high capacitance?
Yes. The distance of the signal transmission is generally short. We have cooperated with a Netherland company and developed a slip ring combining the electricity and optical fiber. This model of slip rings can transmit signals with great capacitance, and we have a mass production with a low price.
