SMD­1.6mini IP65 is a stepper motor driver, which is buit-in into stepper motor SM4247 and has enclosure protection IP65. These drivers are offered as whole assembled units. No need of connecting, adjusting or any other preparation - the system is a ready to work complete step motor drive. High protection class makes it possible to use the drive in disadvantage environments.

SMD­1.6mini IP65 drivers has quite little dimensions, the total dimensions of the assembly is 136 mm including motor shaft and the frame size stays 42 mm from the motor flange size NEMA 17.

Control mode is standard Pulse/Dir mode – step motor driver receives voltage pulses as Step signal and voltage level as Direction signal. Motion displacement depends on pulses number, motion speed is proportional to pulses frequency. The direction depends on voltage level on DIR input. Direction signal can be inverted.
