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.
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.
The electronic rotary couplings transmit data at 100 MBit/s, permitting real-time applications at ultra-fast speeds up to 5,000 rpm.
The rotary couplings support all IEEE802.3-based bus protocols, including Profinet IRT, Sercos III, Ethercat and Powerlink. 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; these can also be freely combined with contactless couplings for other bus protocols such as Profibus, CAN or RS422.

Contactless power transmission is ideal whenever no slip rings are available for transmitting 24V industrial power and/or high rotational speeds are involved.The power transmission couplings deliver a controlled output voltage independently of the speed and direction of rotation. The output voltage is freely selectable within a wide range, and we supply contactless couplers for 24V DC at up to 300 watts. In combination with a data transmission system, this enables completely contactless rotary transmission systems. For special applications, contactless rotating power transmission up to the kilowatt range is possible.
Contactless power and Ethernet modules are ideal for industrial applications, such as bottling plants, fairground rides, machines for producing hygienic products, and cable drums for port cranes. Versions with optical rotary couplings perform outstandingly well in wire rope production machines, construction machinery, packaging systems, industrial robots and very often in radar systems with rotating antennas. For optimizing data transmission in wind turbines, SPINNER supplies innovative solutions with both contactless and optical rotary couplings.
