PTM pneumatic rotary actuators - series DA

Models DA 0020, DA 0050, DA 0200, DA 0500, DA 1500, DA 3000, DA 6000  

All PTM-actuators are based on the rack and pinion principle which accounts for the small dimensions. For different mounting alternatives all PTM actuators can be mounted on three or four mounting surfaces.  

• Rotation angles max. 365°, 185° and 95°
• Progressive working end position damping starts working just about 10° before reaching the end position by throttling the exhaust air automatically, guaranteeing exact end position attainment.
• This excludes bouncing in the end position even during air pressure variation.
• A technically necessary backlash of 0.5° is unavoidable at Mini-Actuators with rack-and-pinion principle.
• Main characteristics of the actuators are small dimensions, low weight and long lifetime. The power transmission is placed in the centreline of the rack piston to guarantee an extended life.
• The smallest Pneumatic Mini Actuator DA 0020 with rotation angle of 95° and a torque of 20 Ncm, has the dimensions of only 20x20x43 mm and a weight of 0.050 kg.
• These small dimensions and weights allow you to increase the performance-weight ratio of your robot or other applications.
