electric rotary unions
Application-specific solutions by KONSTANDIN:
Fast and seamless from concept to prototype to production!
KONSTANDIN offers fluid rotary union and electrical slip ring technology as part of a complete solution for fluid, electricity, signal and data transmission, reliably developed in a compact design.
The solution process, even for complex electric rotary joints,
puts you as a customer at the centre of our schedule.
In addition to pure power rotary unions, our range also includes combined rotary distributors consisting of medium and electricity unions.
As a rule, we combine the components of our standard or stainless steel series with a current transformer designed according to customer requirements.
In the following we show examples of KONSTANDIN developments for combined medium and electricity unions.
The electrical rotary unions
are all designed according to
customer requirements.
This means that you can determine the number of poles, cable length and design, degree of protection, etc. yourself.
The standard options for voltage range from 1 mV to 500 V and for current from 1 mA to 8 A.
Other ranges are possible on request.
