MC330 Slip Rings

OD 22.00mm(0.87"),Length 33mm(1.3")

MC330 slip rings are small and compact with OD 22mm * L 33mm, with capsule style, 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.

MC3309 is the high-end version corresponding to MC330, It has higher performace and longer working life, higher speed rotating speed,low noise, Pealse refer to table 2 as below.
