Further remarks

This contactless rotary joint for data transmission is a high-performance substitute for traditional data sliprings.
• no sliding contacts / no contact wear
• improved life / maintenance free
• no contact interruptions / no bit errors
• suitable for real-time ethernet protocols
• protocol independent (only using OSI-Layer 1)
• high data rates (up to 3 Gbps)
• large free inner bore
• designed for high rotational speed
• supports e.g. the following protocols:

cable length tolerance ±5%
