Contactless Data and Power Transmission for 360 Real Time Applications

Industry 4.0 and the associated networking of machines and equipment are resulting in enormous data volumes. A rapidly lengthening list of processes, spanning everything from production across storage to logistics and shipping, is being automated. Maximum efficiency and uptime are expected of the systems involved. Real-time control is a vital requirement for reliable transmission of data and power. And rapidly rotating components of plants and machines pose especially great challenges.
Wear- and Maintenance-Free Operation
SPINNER offers customers state-of-the-art solutions for maintenance-free, contactless rotary data and power transmission via rotary optical and electronic couplings. Unlike slip rings, rotary couplings from SPINNER are failsafe and have a very long service life. They run in either direction as required, are robust and practically invulnerable to problems and malfunctions, and suffer no wear. SPINNER doesn't use sliding contacts for transmitting data from the stator to the rotor. Cat. 6 Ethernet cables and RJ 45 connectors are used for the data connections.
Modules can be daisy-chained without any problems, and cables up to 100 meters long can be connected to the input and output.
The hollow shafts used have a clear diameter of between 20 and a maximum of 300 millimeters, ensuring plenty of room for implementing virtually any application.
Reliable Data Transmission in Real Time
The electronic rotary couplings transmit data at 100 MBit/s, permitting real-time applications at ultra-fast speeds up to 5,000 rpm, if you want it is possible to have a version at 1 GBit/s.
Supported Ethernet Protocols
The rotary couplings support IEEE802.3-based bus protocols. The bit error rate (BER) is less than 1x10-12, even at 99% bus capacity utilization. For applications calling for even higher data rates, 1 Gbit/s transmission models with automatic bus speed detection (autonegotiation) are used.
