Hybrid Rotary Joints

Customized Solutions: Multiple Transmission Technologies Combined in a Single Rotary Joint

New technologies and more compact designs often make it necessary to transmit a variety of signals and/or media via a single rotary joint. SPINNER has been reliably supplying high-frequency rotary joints since the 1960s, and our decades of experience have enabled us to design hybrid rotary joints for virtually any requirement.

Transmission Methods

All combinations of any of a wide variety of transmission methods are possible. They include fiber-optic rotary joints, slip rings for transmitting high power or large data volumes, integrated passages for air or other coolants, encoders, or contactless digital transmitters for high-speed Ethernet and RF signals.

We also repair and service rotary joints.

High-Quality, Complex Solutions

Due to the level of complexity of hybrid rotary joints, they mainly tend to be custom solutions. By combining standardized modules for different transmission paths, at SPINNER we’re able to design and supply new products quite fast. We focus on ensuring high reliability, a long service life, and minimal maintenance.

The individual parts of each rotary joint are all made using high-precision machines and assembled in our own cleanroom if required or requested. This ensures consistently high quality. SPINNER rotary joints excel with compact designs, excellent VSWR and low insertion loss, minimal fluctuation of transmission characteristics while rotating, and high crosstalk attenuation between individual channels across the entire range of frequencies used.

Applications

The typical uses for hybrid rotary joints include civilian and military weather, flight control (ATC), tracking, surveillance and sea rescue radar systems, which must work reliably day in and day out. You find SPINNER hybrid rotary joints also in Satellite-On-The-Move applications, optronic systems and ruggedized civil and military systems.

SPINNER Product Portfolio for Rotating Solutions

Hybrid Rotary Joints

Any combination is possible: integration of optical rotary couplings, slip rings for high-power or data transmission, media feedthroughs for air or other coolants, encoders, and digital contactless transmitters for Fast Ethernet and high-frequency signals.

RF Rotary Joints

Our RF rotary couplings provide low insertion loss, consistent transmission characteristics during rotation, and excellent crosstalk attenuation between channels across the full operating frequency range.

Fiber Optic Rotary Joints

Our optical rotary joints deliver signals with low insertion loss and high return loss at high speeds. We offer fiber optic rotary joints with up to 109 channels, as well as custom-designed optical rotary joints.

Contactless Rotary Couplings

Rotating, maintenance-free, contactless data and power transmission through optical and electronic rotary joints. Unlike slip rings, SPINNER rotary couplings are fail-safe and provide a long service life.
