Rotary Joints – Spinner (Germany)
Rotary joints are needed wherever high-frequency signals have to be transmitted between a fixed platform and a second platform in continuous rotation. Such applications include traditional radar technology for air traffic control or anti-missile defence, medical engineering, V-Sat and SatCom technology as well as TV camera systems or cable drums that allow sensitive cables to be wound up without twisting them, thus increasing their reliability.
In principle this can be achieved by three different technologies which mainly depend on the frequency of the transmitted signals:
-
Contacting transmission by slip rings
Depending on the unit size such contacting systems can transmit signals from
DC up to 120 MHz.
Coaxial contacting rotary joints
These SPINNER products allow signal transmission in the frequency range from
DC up to 50 GHz.
Contact-free rotary joints
Such extremely long-lived rotary joints are available as coaxial and waveguide
units. The maximum signal transmission bandwidth is about 20% of the upper
frequency to be transmitted.
The Spinner Company further offers:
-
Rotary joints for optical signal transmission
These can transmit up to 21 channels, as well as combinations of the individual types listed above in one rotary joint.
The special benefits of SPINNER rotary joints include their compact design, excellent VSWR and low attenuation loss, low variation of transmission properties during rotation, and high crosstalk attenuation between the individual channels over the whole frequency range.
With over 60 years of experience in RF technology SPINNER is in a position to develop and deliver any kind of rotary joint combination you may need.

EziTrak sponsors a car in Cancer Council’s Shitbox Rally
EziTrak® is thrilled to be involved with this year’s Shitbox Rally to raise money for The Cancer Council NSW.EziTrak® is sponsoring the Team Tonka Toys vehicle in this event.
The Shitbox Rally takes shitty cars and attempts to drive them across Australia, raising money for The Cancer Council along the way.This year’s rally will start in Melbourne on April 14, 2012 and end in Cairns on April 20.
As a GPS Security and Tracking System, EziTrak® is an ideal sponsor of the Team Tonka Toys vehicle and will be used by the team to track their progress up the east coast of Australia.EziTrak® is an Australian designed and manufactured monitoring, protection and GPS tracking system giving vehicle owners personalised, self-monitoring.This early warning anti-theft device is interactive and has no monthly or annual monitoring fees.
EziTrak® offers security, control, GPS tracking and emergency notification for a single one-off cost to vehicle owners.EziTrak® vehicle monitoring, protection and tracking system is available directly from Rojone.
The Cancer Council NSW is a community funded and focused cancer charity dedicated to the defeat of cancer.Tax-deductible donations to this event are welcomed at;

GPS – RFoF
The GPS Over Fiber Link by Optical Zonu provides a simple, cost-effective and reliable RF connection between the GPS antenna and receivers where coaxial cable is impractical. Each link is wideband and supports any of the global GPS frequencies – current or future. The high dynamic range of the system ensures a transparent pass-through with no distortion. A low noise pre-amplifier ensures a margin on signal-to-noise ratio while keeping the signal in the most linear operating Range of the Fiber optic link. The unit housing is a compact IP-50 enclosure. The link supports one GPS antenna. A Built-in Bias-T provides the needed DC power for the active GPS antenna. While the Optical Zonu GPS Fiber Transport Link can be used for point-to-point applications, the link may also be optically split into 8 ways to provide cost-effective GPS distribution to multiple locations over lightweight Fiber cable. In addition, the receiver is available with either one or two RF outputs.
These linear RFoF Transceivers provide an excellent alternative to coaxial cable for distances from 100m to over 10 km. The standard optical connector is the SC/ APC (FC/APC is also available) for low back reflection. This, along with the integrated optical isolator, helps guarantee transparent transport without additive Noise or spurious signals.
The laser diode is an uncooled device that provides stable operation over the entire ambient Operating Temperature Range of –20 °C to +65 °C. Average Automatic Power Control (AAPC) is utilised for optimal optical power stability over the full temperature range.
The RF interface is a 50? SMA connector, and the Alarm and Monitoring Functions are available through a DB9 connector. The standard unit requires +12 VDC power between pins 4 and 5 of the DB9 connector.
The BiasT option +5V or +12V is for powering the Amplifier inside the GPS Antenna. Optical Transmitter monitors ensure the GPS is functioning correctly and if NOT, it optically reports the condition to the GPS optical receiver by blinking the light ON/OFF. The OZ600 Receiver has a built-in active DC Antenna load which goes high impedance if there is a Fibre fault or remote Antenna failure condition.
