The S103 series offers high efficiency, low loss stepper motors in a conventional carcass format (round body). These types of motors provide high speed operation useful in fast moving applications. Their high production of high speed torque allows the use of reducer and thus allows to extend the possibilities of resolutions of the system. The input of the power cable is via a cable gland and its connection to a screw terminal block protected by a cover and a seal providing IP55 protection. On the motor shaft is arranged a wedge of 3 with round tip
