The Sparkfun 3 Wire Slip Ring is a compact and efficient electromechanical device that enables the transmission of electronic signals and power through its rotating components. This product is ideal for applications requiring constant 360° rotation while maintaining an electrical connection such as in wind turbines or radar antennae. It features a compact body with precious metal alloy fiber brush to silver plated ring contacts inside. This slip ring is particularly useful for transferring power in projects involving spinning, as it ensures consistent power supply regardless of the rotation position of the wires.
The Sparkfun 3 Wire Slip Ring can handle a continuous working speed of 250RPM, a current rating of 10A, and an operating voltage of 380VDC/AC. Despite its robust capabilities, this slip ring is surprisingly compact with an outer body diameter of 22mm and a flange diameter of 44mm. This makes it easy to incorporate into your next project. Additionally, it features 250mm stranded wires extending from each side of the slip ring with a thickness of 16AWG. The entire assembly also boasts a water protection rating of IP51.
The Sparkfun 3 Wire Slip Ring also offers a maximum current rating of 25A and is compatible with data bus protocols, making it versatile enough for a wide range of applications. It is capable of transferring both analog and digital signals, further enhancing its utility. The dimensions of the slip ring are 22mm in diameter and 33mm in length, with a 44mm diameter flange.
While the current rating is 10A, it's worth noting that the Sparkfun 3 Wire Slip Ring has been successfully tested at 15A without any issues. This demonstrates the product's reliability and robustness, even under higher loads.
