12/24-channel electric commutator, the commutator adopts micro-sensor + electric drive module inside, and built-in optical fiber channel, it could complete 12/24 channel + 1 optical channel at the same time commutation and it prevent the cable and optical fiber winding, and the driving torque is extremely low, even mice can still rotate easily, it is suitable for experiments under long-term electrophysiological and optogenetic synchronized activities.
