Slip ring are the best way to wire components that move. Indeed, cable carriers often induce cinematic constraints and low reliability thatSlip ring make disappear. 

Low friction torque ofSlip ring mitigates the mechanical impact and continuous rotation capabilities make programming simpler.

Rotation movement takes place at nearly every step of the process from bottle conveying to label placing. Sometimes, active components are embedded on a rotating plate and linked to the machine computer. Slip ring can perform this link while offering continuous rotation capabilities. Continuous rotation increase machine performance and reliability while easing the machine design.Slip ring can transfer all signal that can be met in such machines, motor power and control, sensors, field buses, etc.

In this way, the pod, located on the top of the pylon that holds it, can freely rotate depending on which way the wind is blowing.

OurSlip ring can transfer power from a few hundreds Watts to several dozens of Kilowatt, combining reliability and low-cost technology. Alongside to these power circuits, some control signals can be transferred to gather information (field bus, motor encoder) or power supply other electronics equipment.

The common link, regardless of the final application, is the use of a Slip Ring or a Rotary Union. Cable reels usually transmit power and electric signals, data and different kind of fluids; instead, in case of high-frequency signals, high data rate or where a low bit error rate (BER) is required, the proper result is achieved with a fiber optic rotary joint. Our product range can cover nearly all application from power signals to high data rate or optical signals for cables and from pressurized air to hydraulic oil for rotary union.

PES has developed a plug-and-play solution to answer this need and make integration easy for those who use rotary tables. It is made up of a single-pass rotary union combined with a thru-bore slip ring that offers 24V power supply, field bus connection (Profinet, Ethernet, EtherCAT, etc.) and optionally 400V power supply. This hybrid rotary union assembly comes with the mechanical parts to allow easy mounting on the rotary table. The latter comes this way equipped with the rotary interfaces that can meet nearly all automation application needs.

In this particular case, retrieving the information from the set of moving sensors generally requires the use of a slip ring. PES has a large experience in providing slip ring solutions for test benches for many applications. Our large range of standard and custom products allows us to define the exact component needed for a specific test bench (compact size, a large number of circuits, high rotating speed up to 5000rpm).

Oceanwings® is a fully automated wingsail, enabling hybrid propulsion featuring a mix of wind power and conventional propulsion. To enable automation, the mast embeds a lot of technologies such as strain gauges, thermocouples to monitor the structure and environment but also servomotors to perform sail maneuvers. The wind propulsion concept created by VPLP allows the wing to be automatically positioned depending on the wind direction in order to benefits from the maximum performance of the system, all the time.
