Senring H3899-04S 4-Channel 5A Through-bore Slip Ring
Senring H3899-04S Through-bore Slip Ring
The **Senring H3899 Series** is a high-performance through-bore slip ring engineered for applications requiring a central clear hole for shaft mounting or the passage of hydraulic/pneumatic lines. Constructed with a rugged **aluminum housing**, this unit utilizes advanced **Gold-on-Gold contact technology** to ensure ultra-low electrical noise and stable transmission even at high speeds. Designed for long-term reliability in industrial environments, it provides seamless 360° continuous rotation for both power and sensitive signal circuits.
Product Highlights
- Through-bore Design: Large central aperture for shaft or cable passage
- Gold Alloy Contacts: Copper-Zinc-Gold composition for minimal contact resistance
- Low Electrical Noise: Stable interference levels (≤ 0.01 Ω) for sensitive data
- Aluminum Housing: Durable and lightweight protection for internal components
- Wide Temperature Range: Reliable operation from -40°C to +80°C
- High Connectivity: Pre-installed 300mm stator and rotor cables for easy integration
Primary Applications
- Robotics: Continuous power and signal feed for rotating robotic joints
- CNC Machinery: Rotary tables and automated tool changers
- Packaging Systems: Rotating heating elements and labeling stations
- Medical Equipment: Imaging systems and rotating diagnostic platforms
- Wind Turbines: Signal transmission for blade pitch control systems
- Surveillance: Heavy-duty PTZ camera systems and radar pedestals
