The 42M048C provides up to 11.9 oz-in (83.8 mNm) of holding torque. The 48 steps per revolution results in a 7.5 degree step which increases the positional resolution. It is available in 5 or 12 volt windings, and in unipolar or bipolar designs.
Excellent open loop control - no encoder necessary
Digitally controlled - easy to use with a micro processor
Cost effective - compact design, lower integration cost
Maintenance free - no brushes that can wear out
Available with both unipolar and bipolar winding
Pharmaceutical dispensing
Robotics
Antenna positioning
Printers and copiers
