30mm Thickness Low Friction And Low Electrical Noise Pancake Slip Ring
Description of k250 Pancak-e Slip Ring
SenRing K250(K250) series pancake slip ring is a very thin slip ring with a bore diameter of 50mm, a thickness of 30mm, and various specifications of outer diameter from 140mm to 580mm. The K250(K250) series pancake slip ring is mostly used in equipment with very limited installation space and strict restrictions on slip ring thickness (height) that can expand horizontal space. The pancake slip ring adopts a special vacuum impregnation process and precious metal material for the brush, which has high stability, ensuring excellent electrical transmission performance and rotation performance. Compared with similar products, SenRing pancake slip ring has the main features of low torque, low wear, low electrical noise, and ultra-long life. The standard model supports 2-48 channels of 2-20A current/signal.
