Festo (www.festo.com), one of the world’s leading suppliers of pneumatic and electrical automation technology, has expanded its extensive portfolio of electromechanical actuators to include its latest electromechanical rod actuators, DNCE.
A screw-driven linear actuator, the DNCE electromechanical rod actuator comes with a nonrotating round piston rod. It also serves as a drop-in alternative for the Festo DNC as well as to other pneumatic cylinders compliant with ISO standard 6431 during conversions from pneumatic to electromechanical automation.
Providing high precision and flexibility, the new electromechanical rod actuators is an ideal solution for motion control applications that demands critical positioning accuracy.
The new electromechanical rod actuator is offered either as part of a Festo solution seamlessly combined with an MTR-DCI intelligent controller and motor, or as an independent mechanical axis to be mounted to a third party motor or a Festo motor. The DNCE electromechanical rod actuator is also available either with a ball screw or a lead screw, which enables it to meet the demands of varying performance requirements.
The lead screw driven DNCE electromechanical rod actuator is self-braking for safety, while the ball screw-driven DNCE offers higher feed velocities, higher precision and repeatability. It also has longer duty cycles as compared to pneumatic actuators. Repeatability of lead screw driven actuator is – +/- 0.07 mm, while that of the ball screw is – +/- 0.02 mm.
The motor mounting of the new DNCE electromechanical rod actuator can be configured as a reverse parallel mount (U) or axially (A).
With proximity sensors that can be easily mounted into sensor slots, the new electromechanical rod actuator is also available in custom and standard stoke lengths of up to 600 mm.
