normally, what kinds of  slip rings can combined together in one slip rings or one rotary unions

Combining multiple types of slip rings or rotary unions within a single assembly can be a complex engineering task, and it mainly depends on the specific needs of one applications. The feasibility of combining various functions within a single unit depends on request such as space constraints, the types of signals or media to be transferred, and the need for electrical or fluid isolation. Here are some common combinations of slip rings and rotary unions:

Electrical Slip Rings and Fluid Rotary Unions: In applications where both electrical power/data and fluid transfer are required, such as in industrial machinery or hydraulic systems, a combination of electrical slip rings and fluid rotary unions can be integrated into a single assembly. This allows for the simultaneous transfer of electrical signals and fluid, such as hydraulic or pneumatic power.

Ethernet Slip Rings and Electrical Slip Rings: Some applications require both Ethernet data transfer and general electrical power or signal transmission. In this case, you can combine an Ethernet slip ring with traditional electrical slip rings in a single unit. This setup is common in surveillance and automation systems where cameras need both Ethernet connectivity and power.

Coaxial Slip Rings and Electrical Slip Rings: For applications that involve the transmission of radio frequency (RF) signals alongside electrical power or control signals, a combination of coaxial slip rings and electrical slip rings can be used. This is common in radar systems and communication antennas.

Fiber Optic Slip Rings and Electrical Slip Rings: In situations where high-speed data transmission via fiber optics is necessary, such as in data centers, communication systems, or scientific instruments, a combination of fiber optic slip rings and electrical slip rings may be used. This allows for the transfer of electrical power and signals in addition to high-speed data via fiber optics.

Custom Combinations: In some cases, custom rotary unions can be designed to meet specific application requirements. These may combine various types of electrical, optical, and fluid channels as needed.

When combining multiple functions in a single slip ring or rotary union assembly, it's important to consider factors like:

Isolation: Ensure that electrical channels are isolated from fluid or optical channels to prevent interference or damage.

Signal Integrity: Verify that the quality and integrity of signals are maintained during transfer.

Mechanical Constraints: Assess space constraints, mechanical compatibility, and the speed of rotation to ensure that the assembly can function correctly.

Environmental Conditions: Consider environmental factors such as temperature, humidity, and exposure to dust, as these can impact the performance and longevity of the assembly.
