SM251S / SM251M 2-Phase Stepper Motor
Stepper motors are digitally controlled drives, and have gained great acceptance and spread since the technology change from analog to digital technique because of their cost-effectiveness combined with long product live as well as low control requirements.
The SM251M motor with Molex connectors are used with our compact AB425S control unit with 2 integrated stepping motor drivers. The SM251S motor with SubminD plugs are used with our budget-priced SM210A stepping motor control for accurate speed and positioning
