Long Life Solar Tracker Rotary Joint Slip Ring 18 Circuits 10000 RPM Gold Contact 304 Stainless Steel

SP013018-SS Long Life High-Speed Slip Ring for Solar Tracker Rotary Joint

Product Overview

The SP013018-SS long life slip ring is engineered for photovoltaic solar tracking systems that rotate continuously from sunrise to sunset. With up to 18 circuits, gold-gold contacts and a service life of 10 million revolutions, it delivers stable power and control signal transfer to the drive motor, angle sensors and communication modules of single and dual axis trackers. The 304 stainless steel housing resists UV exposure, rain, sand and salt spray, so the unit keeps working in desert and coastal solar farms without maintenance.
