Core Features & Advantages
- Reliable Thermocouple Signal Integrity Dedicated shielded twisted-pair cables eliminate electromagnetic interference, ensuring accurate temperature readings even in noisy industrial environments. Gold contacts prevent signal drift caused by oxidation or wear, maintaining consistent performance over millions of rotations.
- Dual-Function Transmission Combines 6 circuits of 5A power for heating elements and 6 circuits for thermocouple signals in one compact unit, simplifying system wiring and eliminating wire tangling in rotating equipment.
- Durable Industrial Design Aluminum alloy housing with IP51 protection resists dust and moisture, suitable for factory floor conditions. The through-hole structure allows for shaft, pipe, or cable passage, making it ideal for rotary furnaces, packaging machinery, and automated production lines.
- Customizable & Versatile Support for custom lead lengths, wire types, and circuit configurations to match your specific application requirements. Low contact resistance and high insulation performance ensure compatibility with sensitive temperature measurement systems.
Applications
This slip ring is widely used in industries requiring simultaneous power and temperature signal transmission during rotation:
