Profibus Rotary Joints

You need state-of-the-art solutions for maintenance-free, contactless Profibus transmission via rotary optical and electronic couplings. SPINNER provides a broad portfolio of contactless Profibus rotary joints with main benefits:

  • Wear- and Maintenance-Free Operation
  • Reliable Data Transmission in Real Time

An Profibus rotary joint based on non-contacting coupling mechanisms like capacitive, inductive, transmission line or transformer coupling doesn’t use sliding contacts for transmitting data from the stator to the rotor. Thus they offer superior product life time over contacting designs since these contactless data interfaces are non-wearing and maintenance-free.

Contactless Profibus rotary joints offer reliable data transmission in real time. Our approach permits transmission rates of up to 1 Gbit/s at very fast rotational speeds (up to 6000 rpm). 100 Mbit/s real-time feature enables transmission of various, deterministic bus protocols.  The real-time Profibus contactless data types are protocol independent (only using OSI-Layer 1) and suitable for nearly all 100BASE-TX based industrial ethernet standards.

If you can’t find your ethernet rotary joint according to your specifications online, please contact our sales team by email with the specification needed or select one of the displayed products for a Quote Request and add your special requirements in the comment field of the form before submitting.
