Why are rotating electrical connectors superior to slip rings?
Rotating electrical connectors use a unique design principle unlike the sliding, brush contact of a slip ring. The connection is made through a pool of liquid metal molecularly bonded to the contact, which provides a low resistance, stable connection. When there is rotation the fluid maintains the electrical connection between the contacts without any wear. The following are among the many reasons why rotating electrical connectors are superior to slip rings. First, unlike a slip ring, rotating electrical connectors produce near zero electrical noise due to their unique design. Second, resistance through the rotating contact is less than one milliohm, which is much lower than the resistance of a slipring. Third, rotating electrical connector do not degrade the signal over time, which does happen with slip rings. Fourth, slip rings require maintenance and rotating electrical connectors are maintenance free. Fifth, rotating electrical connectors are more compact and cost far less than sl
