MMC182 Slip Rings

OD 12.50mm(0.49"),Length 18.2mm(0.72"), 6wires* 2A(signal)

MMC182 slip rings are small and compact with OD 12.5mm * L 18.2mm, standard, off-the-shelf.Color-coded lead wires are used on both the stator and rotor for simplified electrical connections. Using a 90° V-groove ring design for each ring.

MMC1829 is the high-end version corresponding to MMC182, It has higher performace and longer working life, higher speed rotating speed,low noise, Pealse refer to table 2 as below.
