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.

Six-channel inductosyn rotary joint.
Three-channel coaxial rotary joint.
Six-channel rotary join with slip ring and encoders.
Nine-channel rotary joint with slip ring.
RPA - Argentine Primary 3D Radar.
20-channel LWL rotary joint.
Single mode single-channel fiber optic rotary joint.
Single-channel Waveguide R100 rotary joint, L-style.
Dual-channel Ethernet module.

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 utilisation 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 (fibre 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.
