SH42BY100B High-Precision Linear Stepper Motor
The SH42BY100B series linear stepper motor is engineered for ultra-precise positioning, tailored to demanding industrial and daily-use equipment. With a 42mm form factor and 100g weight, it combines compact design with robust performance for easy integration.
Core Performance & Advantages
Operating within -10℃ to 55℃, the motor adapts to temperature fluctuations in workshops, offices and households. It features E-class insulation and 100MΩ minimum insulation resistance, ensuring safety and long-term reliability. Equipped with 4-phase configuration and 3.6° step angle—delivering finer control than standard models—its 370-400g.cm holding torque meets the precision needs of robots, flow control valves and slot machines, while powering printers/scanners and sewing machines with stable motion.
