It’s not just medical instruments that are shrinking in size. The demand for smaller ancillary devices, such as lights and cameras in surgery rooms is also growing. The LTN SF020 slip ring meets the need for smaller components. It combines standard power and signal rings with non-contact signal transmission in an unusually small dimension. The contactless rotary joint is typically used to pass digital video signals from camera to monitor in a medical theater.
Specifically, these slip rings are commonly found in boom arms that support surgical lights with integrated cameras along with monitors used to display video feed. The arms’ optical rotary joint allows it to rotate indefinitely in either direction, eliminating the need for mechanical stops. The digital video signal is refreshed as it passes through the slip ring, allowing longer transmission lengths without signal degradation. These slip rings pass power or “main” lines up to 6 A, as well as data signals at 3G speeds (4G upon request).
With a diameter of 22 mm and length between 68 to 95 mm, the SF020 supplies power and high quality video signal at high data rates in a small footprint.
