A23KM(IG Series)

Our hybrid stepping motor with encoders are two-phase stepping motors that use MinebeaMitsumi's high-performance ball bearings and come equipped with sensors that detect the positions of the rotors (optical rotary encoder). These motors can obtain information such as rotating speed, rotational direction, angle of rotation and amount of rotation as an output pulse.
Encoder specification: Optical encoder, 3-channel, 1600, 2400 and 4000CPR, Output Type Line driver.
