Airborne Slip Rings

Product Introduction

Aircraft-mounted slip rings are commonly used in systems such as electro-optical pods and helicopter rotors. This type of environment typically requires slip ring products to be lightweight and compact in design, with special considerations for insulation performance degradation at low air pressure.

Typical Applications

Our company produces a certain model of electro-optical pod slip ring, which includes 10 channels of 5A power ring, 22 channels of signal ring, and an integrated single-channel optical fiber slip ring. The product has a diameter of 45mm and a total length of 93mm.
