Configurator for Industrial Slip Rings

The basis of our MIA configuration system is the gold-on-gold contact technology. It serves the transmission of power (up to 630 V and 63 A), signals (up to 30 V and 3 A) and data as well as various bus systems. In total, a maximum of 120 transmission paths can be configured using different modules.

Our MIAs have a housing diameter of 90 mm or 140 mm depending on the module selected. The slip ring’s housing length corresponds to the sum of all selected modules (116 mm to 399 mm). The standard cable length on the rotor and the stator is 3 meters. Optionally, this can be lengthened to 6, 12 or 15 meters. The MIA slip rings are suitable for ambient temperatures from -20 °C to +70 °C and have protection class IP50. The passivated aluminium housing with free internal diameter (8 mm or 13 mm depending on the outside diameter of the slip ring) enables the conduction of media or routing of fibre optic cables. The modular system can be extended by a power unit, a Gigabit unit or by various media rotary joints. These add-on components can also be ordered separately. No maintenance is required. The service life of all components is designed for up to 50 million revolutions. In the short term, rotational speed up to 400 rpm (small housing diameter) or 300 rpm (large housing diameter) can be achieved.

MIA offers more than two million configuration options for the transmission of power and signals as well as use with Profibus, CAN Bus, and Ethernet that can be available for delivery within 3-5 weeks.

Configurator for Fiber Optical Rotary Joints

The Fiber Optical Rotary Joint (FORJ) makes contactless transmission of signals possible irrespective of the data protocol. The use of high-quality collimators guarantees optimum insertion and return loss values. 

The single-channel FORJ with integrated mounting flange has a maximum outside diameter of 33 mm for a length of 50 mm. The FORJ is available in both multimode (OM1, OM4) and singlemode variants. Furthermore, different connector types and fibre lengths (up to 2 or 4 meters) can be configured. The FORJ is designed for speeds up to 2,000 rpm, has a service life of more than 200 million rotations and is insensitive to EMC influences. It has the protection class IP 40 and can be used in a wide temperature range from -40 °C to +85 °C.

Using SCHLEIFRING’s FORJ configurator the customer can configure high-quality FORJs, which can be available for delivery within 8 weeks.
