Dimensional drawings
Dimensional drawings are provided for the External actuator and the 14 mm-dimension variant to support installation and integration planning.

Speed-thrust curves & test condition
Speed-thrust curve image available for the 14 mm unit. Testing voltage: 12Vdc. Driver model used as reference: DS-OLS2-FPD bipolar chopper driver at rated current (RMS). Motor thrust varies with voltage and driver; a 50% thrust margin is recommended for reliable sizing.
