HD SDI Slip Rings
HD-SDI slip rings are an indispensable part of modern camera technology. 360° swivel and highest image quality are not only required by modern film cameras but are also indispensable for drones and security cameras.
HD-SDI Slip Rings
HD-SDI slip rings for perfect broadcasting
SDI stands for “Serial Digital Interface”. It describes a type of cable and a form of connector that is mainly used in recording and playback devices in professional broadcasting. HD-SDI is an extension of this standard. It enables a data transmission rate that allows digital image recording and playback in high-definition quality. Coaxial cables or optical fibres are used as SDI and HD-SDI cables. The primary task of the HD-SDI slip rings is therefore to ensure interference-free signal transmission at all times.
How the HD-SDI slip rings work
Like all signal-transmitting rotary joints, HD-SDI slip rings are hybrids. They can transmit both signals and power current. In the case of camera technology, this means that the HD-SDI slip rings not only pass the signals to and from the camera. The power supply of the recording device as well as the peripheral devices can also be supplied with power by a single slip ring. This makes motor-driven cameras including sensors and illuminants possible in a particularly confined space – perfect conditions for ultra-compact remote devices such as high-end camera drones.
HD-SDI slip rings from rotarX are supplied without connectors. The incoming and outgoing cables are open and free for custom assembly. On request, we can also supply the HD-SDI slip rings with the connector of your choice. rotarX uses only gold-gold contacts in its HD-SDI slip rings to ensure perfect transmission of power and signal current. These are corrosion-free and guarantee reliable transmission of the HD signals at all times.
Advantages of the HD-SDI slip rings from rotarX
HD-SDI slip rings are used where no compromises in transmission quality and freedom of movement are permitted. Therefore, HD-SDI slip rings are particularly advantageous for their field of application for the following reasons:
- Designed for HD-SDI applications
- Rugged housing made of thick-walled, corrosion-free aluminium
- Ingress protection class IP51 as standard, higher protection classes available on request
- Corrosion-free gold-gold signal transmission in the slip ring
- large variety of types
Everything about the HD-SDI slip ring is designed for its dedicated use. The smooth rotatability, even with fast right-left changes, makes perfect camera pans possible. The housing is made of robust aluminium and is perfectly protected against corrosion. The mounting point is also made of this rustproof material. This means that shooting in the open air is always guaranteed.
The slip ring is protected against penetrating interference radiation by the aluminium housing. No interfering signals can penetrate from its interior to the outside either. The typical protection class IP 51 means that the slip ring is protected against dust and splash water. A small rain shower or morning dew does not immediately lead to a short circuit in the rotary joint. This also makes the HD-SDI slip ring well suited for surveillance cameras. For higher protection classes, we have solutions that make the slip ring fully operational under particularly harsh environmental conditions. With at least 50 revolutions per minute, the rotation speed is high enough to also allow fast panning. Nature shots, vehicle races or other fast movements are thus always recordable.
HD-SDI Slip Ring Selection
One HD-SDI channel is available per slip ring. More is not necessary, as only one camera is ever controlled with one ring. Furthermore, the HD-SDI slip rings have at least two and up to 48 rings and thus passages. This makes extremely convenient camera control possible. With a working voltage of up to 440 volts, you can also couple the HD-SDI slip rings to power applications. The electrical noise does not exceed 10 milliohms.
The insulation resistance is 1000 megohms at 500 volts DC. The rotation speed is limited to 50 rotations per minute. More is not necessary for fast camera movement. Unless otherwise requested, we deliver the HD-SDI slip rings with a cable length of 300 mm on both sides. Longer cables are always possible on request.
The HD-SDI slip rings guarantee perfect operation in the temperature range from -30° C to +80° C. This means they are fully resilient even under tough operating conditions.
Using the HD-SDI slip rings
Use of the HD-SDI slip rings
HD SDI slip rings have their domain in professional image transmission technology. They are therefore suitable for all areas where first-class recordings from remote cameras are required. This precisely defined working range makes a high rotation speed unnecessary. HD SDI slip rings are therefore used in the following applications:
- Remote-controlled cameras in film and television production
- Drone technology
- Object protection
- Research
- Damage analysis in sewers
- Nature observation
- Astronomy
