ECN090-03S is CENO Large Bore Through-Hole Slip Ring is a rotary electrical connector that delivers steady power and control signals during 360° unlimited continuous rotation. It adopts an integrated black anodized aluminum housing with a big central hollow for coaxial passing of drive shafts, air tubes or oil pipelines. Equipped with a U-shaped fixed bracket to lock the stationary brush part, color-coded wires extend from rotor and stator sides for easy wiring identification. Internal gold alloy contact modules ensure stable conduction, and a parameter label marks specifications and certifications for convenient matching with rotary equipment.
