integrated pneumatic-electric slip ring with IP56 protection rating and 24 channels 5A for the continuous rotary transmission of air and multiple electrical signals

The Q1P04FS-24P-E0006 is an integrated pneumatic-electric slip ring designed specifically for heavy-duty applications. Featuring an aluminum alloy housing, it offers an IP56 protection rating and operates within a wide temperature range of -30°C to +80°C. It integrates one NPT 1/2" pneumatic channel (compatible with compressed air) and twenty-four 5A electrical circuits; the electrical section features dynamic contact resistance of <10 mΩ, insulation resistance of ≥300 MΩ/200 VDC, and a dielectric strength of 200 VAC (50 Hz/60 s). Both the rotor and stator leads are 4,000 mm long, and the unit supports a maximum rotational speed of 10 rpm. Capable of withstanding significant radial, axial, and bending moment loads while simultaneously enabling the continuous rotary transmission of compressed air and multiple electrical signals, it serves as an ideal solution for equipment requiring synchronized pneumatic and electrical rotation in heavy-duty environments.

Key Features

Integrated Heavy-Duty Pneumatic-Electric Design: Combines one NPT 1/2" pneumatic line and twenty-four 5A electrical circuits into a single unit, meeting the rigorous demands of heavy-duty equipment for the simultaneous transmission of compressed air and multiple power/signal channels.

High IP56 Protection Rating: Offers complete protection against dust and powerful water jets, making it suitable for industrial environments characterized by dust, humidity, and wash-down operations.

Ultra-Low Dynamic Resistance: Dynamic resistance is less than 10 mΩ, ensuring minimal voltage drop during high-current transmission and stable, signal-loss-free data transfer.

High Insulation Resistance and Dielectric Strength: Insulation resistance ≥ 300 MΩ/200 VDC and dielectric strength of 200 VAC (50 Hz/60 s) ensure electrical safety and long-term reliability.

Extra-Long Lead Wires: Lead wires on both the rotor and stator sides measure 4,000 mm in length, greatly simplifying wiring for remote equipment setups and reducing the need for additional extension cables.

Heavy-Duty Load Capacity: Capable of withstanding significant radial, axial, and bending moment loads, making it ideal for direct integration into rotating mechanisms subject to external mechanical forces.

Why Choose This Integrated Pneumatic-Electric Slip Ring?

Why Choose This Integrated Pneumatic-Electric Slip Ring?
An Expert in Synchronous Pneumatic and Electrical Transmission for Heavy-Duty Applications
In scenarios involving heavy machinery and engineering equipment, rotating mechanisms often require the simultaneous transmission of compressed air and multiple electrical power or signal channels while withstanding significant mechanical loads. This product integrates pneumatic lines with 24 electrical circuits into a single unit capable of handling heavy loads; it can be mounted directly onto rotating shafts subject to external mechanical forces, eliminating the need for extra support structures and simplifying equipment design.

IP56 Protection for Harsh Environments
An IP56 protection rating signifies:
Complete dust protection (Level 5): Prevents dust ingress that could affect internal components.
Protection against powerful water jets (Level 6): Withstands high-pressure water jets from any direction.
Suitable for industrial environments—such as mines, construction sites, metallurgical plants, and ports—characterized by dust, humidity, or the need for wash-down procedures.

Ultra-Low Dynamic Resistance Ensures Stable Power and Signal Transmission
Advantages of dynamic resistance <10mΩ:
Minimal voltage drop during high-current transmission, reducing heat generation and energy consumption.
Stable signal transmission, ideal for sensitive signals from encoders and sensors.
High wear resistance and longevity, reducing maintenance frequency.

4000mm Extra-Long Lead Wires Simplify Cabling
With 4000mm lead wires on both the rotor and stator sides, the design accommodates installation scenarios where there is a significant distance between the rotating and stationary components of heavy-duty equipment. This reduces the need for additional junction boxes or extension cables, resulting in neater and more organized internal wiring.

Optimized for Low-Speed, Heavy-Duty Operation (10 rpm)
The rated speed of 10 rpm is optimized to meet requirements for high torque, heavy loads, and long service life. At this speed, wear on seals and brushes is minimal, enabling an exceptionally long maintenance-free service life—making it ideal for heavy-duty equipment requiring continuous 24/7 operation.
