The Q8P01-3099-5PS-GRC0281 is an integrated pneumatic-electric slip ring designed for the simultaneous
transmission of multiple pneumatic lines and solenoid valve signals. It features a black anodized aluminum
alloy housing and a compact structure with a 30mm bore and a 99mm outer diameter. The unit integrates eight
G1/8" pneumatic channels and five solenoid valve signal channels; the pneumatic system supports a maximum
operating pressure of 0.8 MPa, while the electrical section utilizes precious metal contacts, supports voltages
from 0 to 220V, and offers an insulation resistance of ≥1000 MΩ (at 300 VDC) and dynamic contact resistance of
<0.01 Ω. It is equipped with AWG26 Teflon-insulated leads (100mm length at each end), operates within a
temperature range of -30°C to +80°C, supports a rotational speed of 200 rpm, and holds an IP51 protection
rating. Capable of the uninterrupted, simultaneous transmission of compressed air and solenoid valve signals
during rotation, it serves as an ideal integrated connectivity solution for equipment such as automated
assembly lines, rotary fixtures, and packaging machinery.
Key Features
Highly Integrated Design (8 Pneumatic + 5 Signal Channels): A single unit integrates 8
independent pneumatic lines and 5 solenoid valve signal channels, meeting requirements for simultaneous
pneumatic control and signal feedback across multiple actuators while simplifying the structure at the rotating
end.
Flexible 30mm Center Bore: A 30mm center through-hole accommodates power cables, sensor wires,
or small pneumatic tubing, optimizing internal routing and enabling the integration of multiple media types.
Precious Metal Contacts & Ultra-Low Dynamic Resistance: Features precious metal contact
materials and dynamic resistance of <0.01Ω, ensuring stable, lossless signal transmission during rotation;
insulation resistance of ≥1000MΩ/300VDC guarantees electrical safety.
0.8MPa High-Pressure Pneumatic Lines: All 8 pneumatic lines support G1/8" ports and compressed
air, with a maximum operating pressure of 0.8MPa, meeting the power requirements of components such as pneumatic
cylinders and grippers.
Standard Lead-Outs for Easy Installation: 100mm lead-outs at both ends utilize AWG26
Teflon-insulated cables—resistant to high temperatures and corrosion—facilitating quick internal wiring.

Why Choose This Integrated Pneumatic-Electric Slip Ring?
An all-in-one solution for multi-channel pneumatic supply and solenoid valve signal transmission
Automated
assembly lines and rotary fixtures often require simultaneous air supply to multiple cylinders and control of
solenoid valves. This product integrates 8 pneumatic channels and 5 solenoid valve signal channels into a
single unit. Replacing the traditional combination of separate pneumatic and electric slip rings, it
significantly simplifies system architecture and reduces failure rates.
Precious metal contacts ensure signal integrity
The combination of precious metal contact materials and
dynamic contact resistance of less than 0.01Ω ensures:
Zero-latency, zero-attenuation solenoid valve
control signals
Minimal voltage drop and reduced heat generation
Resistance to oxidation and
sulfidation, making it suitable for humid environments
Long service life and wear resistance, reducing
maintenance needs
30mm center bore offers design flexibility
The 30mm center through-hole allows for:
Centralized
routing of power and signal cables
Routing of small pneumatic or hydraulic lines through the core
Direct passage of the equipment spindle, enabling a "shaft-within-a-shaft" configuration
Providing
equipment designers with exceptional flexibility in cabling and layout.
0.8MPa high-pressure pneumatic channels meet power requirements
Featuring eight G1/8" pneumatic ports
supporting an operating pressure of 0.8MPa, the unit can simultaneously drive multiple cylinders, pneumatic
grippers, or vacuum generators, ensuring rapid response and powerful actuation of pneumatic components.
Application Scenarios
Automated assembly lines: Pneumatic clamping and solenoid valve control signal transmission for multi-station
rotary fixtures.
Packaging and filling machinery: Pneumatic valve control and signal feedback for rotary
filling heads.
Robotic end-effectors: Integrated connections for pneumatic grippers, suction cups, and
solenoid valve signals.
Rotary tables: Synchronous transmission of signals for multi-channel pneumatic
positioning pins, fixtures, and sensors.
Food and pharmaceutical equipment: Pneumatic control and signal
transmission for rotary filling and sealing machines.
Testing and experimental equipment: Rotary test
platforms featuring multi-channel pneumatic actuation and signal acquisition.
Frequently Asked Questions
Can they operate at full load simultaneously?
A: Yes. The pneumatic and signal
channels feature a physically isolated design, allowing them to operate at full load simultaneously without
mutual interference.
Q2: What types of signals do the 5 solenoid valve signal channels support?
A: They
support solenoid valve control signals ranging from 0V to 220V and can also transmit low-power signals for
sensors, encoders, etc. We recommend using shielded cables and ensuring proper grounding.
Q3: What are the practical benefits of a dynamic resistance of <0.01Ω?
A: A
dynamic resistance of 10mΩ (0.01Ω) ensures:
Minimal signal transmission attenuation and accurate
solenoid valve operation
Negligible voltage drop and reduced heat generation
Stable contact
resistance and consistent performance during long-term operation
Q4: What is the maximum outer diameter of cables or tubing that can pass through the 30mm center
bore?
A: The 30mm inner diameter can accommodate:
Multiple cables with an outer
diameter ≤25mm
Multiple air tubes with an outer diameter ≤8mm
Various fiber optics and sensor
wire harnesses
Q5: For what environments is the IP51 protection rating suitable?
A: IP51 indicates
effective protection against dust ingress (Level 5) and resistance to vertically falling water droplets
(Level 1). It is suitable for most indoor industrial environments but not for scenarios involving
high-pressure water jets or submersion.
Q6: Can the 100mm lead wire length at both ends be customized?
A: Yes. The standard
lead length is 100mm, but we offer customization services if you have specific requirements regarding
length, connectors, or cable specifications.
