SDI signal slip rings are used in photographic equipment to transmit high-definition SDI (Serial Digital Interface) video signals in various photographic devices. SDI is a widely used interface in the professional video industry, capable of transmitting high-quality uncompressed video signals over coaxial cables. SDI signal slip rings ensure smooth transmission of video signals between rotating components of photographic equipment, such as stabilizers, camera gimbals, camera cranes and other motorized devices.

As an experienced slip ring manufacturer with more than 20 years of experience in the industry, JINPAT has extensive knowledge in product development and provides rotary signal and power transmission solutions to customers worldwide, including many specially designed for high-definition video signal transmission. Among the slip rings developed by JINPAT for high-definition video signal transmission, a large part consists of SDI signal slip rings. Compared to HDMI and DP high-definition video signals, which require dedicated cables for transmission, SDI high-definition video signals are transmitted using coaxial cables, which are less expensive and have relatively simpler impedance matching issues than the first two cable types.

Incorporating SDI slip rings into photographic equipment offers many benefits. First, SDI slip rings enable the transmission of high-definition video signals without loss of quality, providing clear and detailed images. This is especially important in professional video production, where image quality is of utmost importance. Second, SDI slip rings ensure stable and reliable transmission of video signals while the device is moving or rotating. Slip rings ensure continuous signal flow between stationary and rotating parts of the equipment, eliminating the need for tangled cables or signal interruptions. In addition, using SDI slip rings simplifies the setup and operation of photographic equipment. Only a coaxial cable with SDI interface is required to transmit video and audio signals, reducing cable interference and improving overall efficiency.

JINPAT has developed many SDI signal slip rings for photographic equipment. For example, LPC-24A-0210-4S-HDA1 is a product designed for professional stabilizers. It uses the shape of the standard LPC-24A slip ring and integrates two 10A power rings, four other signal rings, and one channel to transmit 3G-SDI high-definition video signals with a resolution of 1080P@60Hz.
