Custom 26-Channel Aerospace-grade split-type conductive slip ring for Aerospace
In the aerospace industry, equipment must operate reliably for long periods under harsh conditions such as extreme temperature differences, strong corrosion and high vacuum, while meeting the power and signal transmission requirements for complex motions like satellite antenna pointing adjustment and solar panel sun tracking. As the core component connecting rotating parts and fixed structures, the performance of conductive slip rings directly determines the overall stability of aerospace systems.
This 26-channel ultra-light high-precision conductive slip ring is tailor-made for the special needs of the aerospace field. Adopting an innovative split-type design with weight-reduction grooves, it maintains complete 26-channel transmission capability while controlling the outer diameter to 134mm and length to only 42mm, with a total weight of less than 500g. This greatly saves valuable installation space and strictly meets the stringent lightweight requirements of the aerospace industry. The operating torque is less than 0.2N·m, ensuring smooth rotation without jamming and no additional load on the precision motion mechanisms of aerospace equipment.
To adapt to the complex aerospace environment, the product is entirely made of high-quality aviation-grade materials, and the surface is treated with black anodized anti-corrosion process, which has excellent high temperature resistance, low temperature resistance, high humidity resistance and corrosion resistance. In terms of electrical performance, the product realizes partitioned and isolated transmission of power and signals. The signal channels adopt twisted pair design, which effectively reduces electromagnetic interference and ensures high precision and stability of signal transmission. The contact resistance variation is ≤10mΩ, and both insulation resistance and dielectric strength meet aerospace-grade standards, providing a long-term stable and reliable power and signal transmission solution for aerospace equipment.
