SPINNER High-Frequency Rotary Joints
SPINNER is the leading European manufacturer of high-frequency rotary joints, and has more than 40 years of experience in the industry.
The SPINNER group has production facilities in Germany, Hungary and China, with more than 1,100 employees worldwide. Our subsidiaries and representatives are present in over 40 countries and provide our customers with an international network of support. Quality, flexibility and service have made the group internationally successful.
Single and multi-channel rf rotary joints and hybrid solutions
High-quality SPINNER hybrid rotary joints are mainly used in military radar systems, fire control systems, rotating vehicle-mounted camera systems and in mobile battlefield communication systems.
In areas such as ATC (Air Traffic Control) and commercial SatCom, for airborne, naval and ground based solutions SPINNER’s rotary joints are widely used as well.
The following main components are designed and manufactured by SPINNER at our production facility in Westerham, Germany, and we are able to supply:
- Single or multi-channel coaxial rotary joints
- Waveguide single or multichannel rotary joints
- Fiber optical single or multichannel rotary joints
- Contactless Fast Ethernet and Gigabit Ethernet
- Media joints for fluids and air
- Contactless power transmission
The combination of the above mentioned groups of transmission technologies and encoders are so called hybrid rotary joints combined with slip rings. This enables SPINNER to offer complete system solutions from a single source. These solutions are achieved by the utilization of a highly motivated team of research and development engineers, equipped with state-of-the-art design and simulation tools.
CNC turning and milling centres
SPINNER in-house manufacturing capabilities include:
- CNC controlled turning and milling centers
- Electroplating for all common surfaces
- Mechanical test equipment (covering sub-micron range to ensure outstanding quality)
- Climate and salt spray chambers for environmental tests
- Shock and vibration tests, as well as testings in co-operation with external institutes
This high quality standard guarantees a frictionless operation in extreme situations.
FORJ (fiber optical rotary joint) and gigabit ethernet transmission
These are the most commonly used combinations for next generation high performance radar and data transmitting systems. Normally, one or two high-power channels (coax/waveguide) are combined with several low-power channels. Slip ring modules for power supply and data transmission are additionally integrated. Due to constantly increasing data rates, optical rotary joints and contactless Gigabit Ethernet transmission are becoming more important.
SPINNER solutions are widely spread from the standard 20 channel FORJ to smallest available 6 channel FORJ on the market, down to a single channel FORJ that can be integrated into the inner conductor of a coax channel with an outer diameter of only 3mm.
Customised solutions including media joints
SPINNER delivers a large variety of rotary joint combinations according to customer specifications in all varieties, frequency bands and sizes.
The integration of media joints and contactless Gigabit Ethernet ensure that SPINNER solutions are able to provide all requirements of any radar system.
Rotary joints maintenance and repair
As an additional service, SPINNER offers repair and maintenance of all rotary joint brands.
SPINNER offers as well connectors, special phase adjustable cable assemblies for phased array systems, power combiners for radar transmitters and many others.
The quality assurance (QA) system at SPINNER has been certified according to DIN EN ISO 9001. The results of our endeavors are documented in our DIN EN ISO 14001 certified environmental management system.

Due to the requirement of the customer to operate an antenna system in a high temperature environment, SPINNER had to take the challenge to design a rotary joint which was able to handle 1kW of average power at 10GHz at an environmental temperature of +60°C.Read more
For many mobile satellite communication systems developed these days, there is a requirement to significantly reduce the height of the radomes under which the SatCom systems are installed. This is to improve their drag coefficient. This means that less installation space is available foRead more
A typical application for the use of such rotary joints is in ground based satellite communication systems. These systems are used to build up a communication link for example in remote areas where no fixed line or WIFI or even mobile communication is available. That happens with the help of a moRead more
For TV satellite systems on ships or in trains, busses and camping vehicles with automatic tracking function, which follow a satellite even when the vehicle is moving, SPINNER offers a cost-efficient version of RF rotary joints. Further fields of application are conceivable, such as swivel cameraRead more
In 2004 SPINNER GmbH developed the first one-channel miniature rotary joint, thus laying the foundation for what has become a large family of rotary joints for civilian and military applications. By 2008 the fields of application for rotary joints have grown well beyond high-end systems such as rRead more
The 3-D CAR was originally developed as part of a program between Indian DRDO and Poland's PIT as a family of mobile S-Band 3D radars. The areas of cooperation were developing the Planar Array and general architecture. The Indian variant is the 3-D CAR, a medium range surveillance radar for AkashRead more
