Electric slip ring

2-partfor the aeronautical industryanodized aluminum

Short Description
Aerospace-grade split-type conductive slip ring with 26 integrated power and signal channels, total weight <500 g. Constructed from aviation-grade materials with black anodized anti-corrosion surface treatment. Operates reliably from -40°C to +125°C and is designed for rotating transmission applications such as satellite antennas and solar array tracking.

Product Detail
In aerospace systems, slip rings must deliver uninterrupted power and signal transmission under extreme temperature variations, corrosive atmospheres and vacuum while preserving mechanical precision for pointing and tracking motions. This 26-channel split-type conductive slip ring is engineered to meet those requirements with an ultra-light, compact design.

The split-type structure with weight-reduction grooves keeps the outer diameter to 134 mm and length to 42 mm while providing full 26-channel connectivity. Total mass is <500 g, meeting strict mass and volume constraints of aerospace platforms. Operating torque is <0.2 N·m to ensure smooth rotation without introducing excessive load to precision drive mechanisms.

All structural components are fabricated from aviation-grade materials and the surface is treated with a black anodized anti-corrosion process to resist high/low temperature extremes, humidity and corrosive environments. Electrical layout separates power and signal channels; signal lines use twisted-pair routing to minimize EMI and preserve signal integrity. Contact resistance variation is ≤10 mΩ; insulation resistance and dielectric strength conform to aerospace requirements, providing a reliable long-term solution for power and signal transfer in rotating aerospace equipment.
