ATC Rotary Joints Edition A

Product catalog summary

Introduction
SPINNER is a prominent manufacturer of rotary joints used in radar systems, especially for air traffic control (ATC). These components are crucial for signal transmission between stationary platforms and rotating antennas in systems like Surface Movement Radar (SMR), Precision Approach Radar (PAR), and Air Surveillance Radar (ASR). SPINNER's rotary joints are noted for their compact design, low insertion loss, and high crosstalk attenuation.

Fiber Optic Rotary Joints
SPINNER provides multichannel fiber optic rotary joints characterized by low insertion loss and high return loss. These joints are designed for high optical power and minimal crosstalk, making them ideal for demanding applications.

Coax Rotary Joints
SPINNER offers coax rotary joints with various channel configurations (3, 4, and 9 channels). These joints support high peak and average power levels, with low VSWR and insertion loss, ensuring efficient signal transmission.

Waveguide/Coax Rotary Joints
These joints combine waveguide and coaxial interfaces, offering high power handling and low insertion loss across multiple channels, suitable for robust performance in harsh environments.

Specifications and Technical Data
The document details specifications for rotary joints, including mechanical data (rotating speed, torque, material), environmental conditions (temperature, humidity, IP protection), and electrical requirements (current, voltage, frequency).

Custom-Made Solutions
SPINNER provides custom rotary joint solutions tailored to specific customer needs, with a specification sheet available for defining system requirements.

Conclusion
SPINNER's rotary joints are essential to modern radar systems, offering reliable performance in both civil and military air traffic management. Their focus on innovation and quality ensures they remain a trusted industry supplier.

Specifications Overview

RF Channel Characteristics: Configurations with frequency ranges from 1.0 GHz to 3.1 GHz, peak power up to 1.5 MW, and average power up to 11 kW. VSWR max values range from 1.2 to 1.3, with insertion loss max values from 0.15 dB to 1.0 dB. Isolation is consistently at a minimum of 60 dB.
General Mechanical Data: Maximum rotating speed is 60 rpm, with a life expectancy of up to 50 million revolutions. Torque varies, with some models reaching up to 50 Nm. Materials include aluminum alloy and stainless steel, with chromate conversion coat finishes.
Environmental Conditions: Operating temperature ranges from -55°C to +85°C, with relative humidity up to 95%. IP protection levels vary, with some models offering IP66 for rotating parts.

Encoder Interface Characteristics
Types include DFS60A-TGAA65536 and DHO5_14//RP29//3600, manufactured by SICK and BEI-IDEACOD, France.

Slip Rings Characteristics
Total number of ways varies from 14 to 38, depending on the model.

Additional Notes
Data is subject to change without notice, and specific configurations may require additional documentation such as CoC according to DIN 55350-18.

General Environmental Conditions
The document outlines operational and storage conditions for rotary joints, specifying ambient temperature ranges and relative humidity limits. It also mentions the required quantity for prototypes and serial production, along with the delivery period.

Rotary Joint Specifications
Specifications cover fiber optic and media rotary joint characteristics, including the number of channels, interface types, fiber types, and performance metrics such as insertion loss and return loss. Media rotary joint characteristics include operative system pressure, flow rate, and liquid composition.

Slip Ring Specifications
Details include mechanical data such as rotational speed, torque, dimensions, and electrical requirements like current, voltage, and frequency. It also specifies the type of connection for rotor and stator components.

Quality and Maintenance Requirements
The document lists required quality documents, including CoC according to DIN 55350-18, government inspections, and environmental tests. It also outlines maintenance schedules and warranty conditions.

Technical Annex
This section provides definitions and explanations of terms related to rotary joints, such as channel, contacting and non-contacting rotary joints, slip rings, and swivel joints. It also discusses RF channel characteristics, including attenuation, average power, DC carrying capability, frequency range, and insertion loss.

Interface Orientation and Type
Describes the orientation styles (I-style, U-style, L-style) and interface types (waveguide or coaxial) for rotary joints, along with their applications and standards compliance.

Isolation Types
The document discusses forward and reverse isolation in rotary joints, with worst-case values typically ranging from 50 to 70 dB, and up to 100 dB for high-power designs.

Peak Power
Defines the maximum short-term power a component can handle without breakdown, influenced by factors like air pressure, VSWR, and temperature. Peak power can be enhanced by pressurizing components with gases like SF6.

Phase Difference and Tracking
Describes the phase difference between channels and their synchronism over rotation. SPINNER datasheets provide worst-case values for phase difference and tracking.

Return Loss and VSWR
Return loss is the logarithmic ratio of incident to reflected power, with values typically between 10 dB and 40 dB. VSWR variation over rotation is also discussed, with common values between 0.02 and 0.2.

Mechanical Data
Includes case material and surface finish, interface loads, leakage rate, lifetime, marking, operating pressure, rotating speed, torque, and weight.

Environmental Characteristics
Covers ambient temperature range, application environments, IP classification for protection against ingress, and compliance with MIL-STD-810G for various environmental conditions.

Unit Conversion
Provides conversion factors and conditions for standard atmospheric pressure and temperature.
