Product Detail

Product Tags


The 25BYJ412 stepper motor is mainly used in printers, valves, fluid control, position control and other fields. This motor has the features of small size, high precision and high strength.

This stepper motor has a built-in gearbox with a reduction ratio of 1:10. Finally, an output top rod with a stop structure is used so that the plunger can move back and forth without rotating. The thrust force can be up to 10 kg.

JST PHR-4 P2.0 is chosen for the exterior of this motor, and the wiring part can be selected from various types and lengths of connecting wires or FPC FFC according to customer requirements. the shape of the mounting plate and the exit angle can be adjusted according to customer needs!
