  • B1206 model designed for internal power integration

2-phase stepper motor driver

The Ruth's sister B1206 is a two-phase stepper motor driver rated for 120 V supply voltage and 6 A working current. It suits builders integrating motion control into custom automation or CNC projects.

Fits standard driver slots

The module mounts directly onto compatible controller boards and draws power from the 120 V rail. It frees the host board from driving motor coils directly, reducing thermal load on the main controller.

Questions about this item

What is the maximum sustained working current the B1206 driver can handle?

The B1206 driver is rated for a working current of 6 A, which is the continuous limit under sustained operation.

How much heat or noise does the B1206 produce when running all day at 120 V?

The B1206 has no fan and no moving parts, so it runs silently; heat output depends on the load current and the ventilation inside your enclosure.
