PTM DAD 0500 Three Position Torque Cylinder

Actuators with an exactly defined mid position (Attention: Backlash !) are based on three piston units. The two external pistons push the piston with the rack into the mid position. If the two cylinders on both sides are without pressure and only the center piston is pressurized, the pinion will turn around the complete angle. The speciality of this construction is, that in spite of the small construction all pistons have end position damping. Field tests did prove, that this pneumatic end position damping is superior to the normally used miniature shock absorbers. Actuators with mid position are available with torque of 50 Ncm, 200 Ncm and 500 Ncm. The standard models have rotation angles of 180° or 90°. Other angles on request.
