About DA 20 Servos/Actuators

The housings of our DA 20 series are made of CNC-machined aluminum elements with a bottom case part made of fiberglass-reinforced plastic. The aluminum parts are rugged, torsion-resistant and dissipate internal heat. As with all our actuators, the DA 20 also has a steel gear train and is fully programmable using our programming tool (available as an accessory).

 

About Volz Servos

A servo from Volz excels due to the simplicity of its design while simultaneously maximizing positioning force, reliability and durability. Moreover, a variety of electric interfaces makes it possible, for instance, to monitor the operating condition of the servos by reading out the current consumption, the internal temperature and humidity, etc.

Every actuator compromises a DC motor, a gear train and control electronics governed by microprocessors with integrated position feedback. These are electromechanical servo units that precisely position a radial output drive.

Depending on the type of actuator, the maximum travel in the standard configuration varies between 90° and 170°. Versions with larger travel of up to 330° or “Multiturn” versions can be provided on request.
