Customized solutions for electricity and fluid transmission

GAT, the German company represented in Italy by Ridix, has considerable experience in the field of rotational transmission. Specialized in the field of slip rings and rotary unions made to clients’ specifications, GAT provides different technologies and product families for the transmission of power and fluids. Among these, slip rings transmit power, signal and field bus systems by means of sliding gold-gold contacts; if the aim is to achieve a signal transmission as close to real time as possible, contactless and optic fiber technologies are also available. GAT has been developing contactless technology for high speed data transmission (Ethernet, fast-Ethernet, etc) for years. SPS IPC Drives Italia will provide the occasion to present the ROTOCAP system for transmission in Gbit/s. The GAT ROTOCAP has a very low bit rate error (<10-12), thereby allowing a control of drives very close to real time, without the interference created by sliding springs or brushes, and consequent wear. GAT slip rings do not need maintenance for 95% of applications and this holds valid for contactless and for gold-gold contact systems. In brief, the advantages of the contactless ROTOCAP system are: high speed transmission, clear signal, low or no maintenance and the possibility of being applied to large plants.
