All PTM-actuators are based on the rackand pinion principle, picture 2.

This fact is responsible for small dimensions.

For different mounting alternatives all PTMactuators 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

unvoidable 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 centerline 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.

These small dimensions and weights allow

you to increase the performance-weight

ratio of your robot or other applications.
