PSR-SD slip ring is a standard capsule ,off-the-shelf series product ,that udes gold contacts at the rotary interface . Color-coded lead wires are used on both the stator and rotor for simplified electrical connections. Using a 90o V-groove ring design for each ring,the PSR-SD provides smoother running ,lower toque ,low contact wear rates than competitive slip ring ,provides 12 ,16 , 24 , electrical circuit and 1 SDI signal,2A/circuit for power or signal ,and channel SDI Rotory Joint for hig speed data SDI vedio signal cofigutations
