All PTM-actuators are based on the rack and pinion principle. This fact is responsible for small dimensions. For different mounting alternatives all PTM actuators can be mounted on three or four mounting surfaces. Rotation angles more than 185° are available. Our progressive working end position damping starts working just about 10° before reaching the end position by throttling the exhaust air automatically. This guarantees reaching the exact end position. 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 our actuators are small dimensions, low weight and long lifetime. The power transmission is placed in the centreline of the rack piston to guarantee a very long lifetime. There are PTM-actuators which were returned for repair only after 13 years of continuous running. 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.
