New lightweight and economical rotary actuator and sensor from Festo can be installed in seconds

The DRVS has everything you would expect from a semi-rotary drive -powerful rotation with an innovation design.

The semi-rotary drive is a simple and compact lightweight design which can deliver high torque ratings of up to 20Nm. It is powerful even in harsh environments and has an infinitely adjustable swivel angle which means that it gives increased flexibility to the user for up to 90, 180 or 270¡.

Fitting semi-rotary drives with sensors has never been so easy, reliable, uncomplicated and error-free thanks to the unique sensor SRBS. When combined with the DRVS drives they provide simple rotary motions that tell you where they are -first time, every time. The SRBS is a closed and encapsulated unit that can be quickly assembled and screwed into place, which means it is exceptionally easy to install.

This enables machine builders and engineers to save valuable installation time and associated costs, and it provides excellent performance at an attractive price. Switching points can also be taught electronically by simply pressing a button. As such it provides innovative sensing without the need for mechanical adjustment and manually searching for switching points, thus reducing set-up time. 

Sensing is performed magnetically and without contact, and as a result, offers a long service life and reliable operation. The actuator and sensing solution is ideal for simpler flap, divert, escapement type applications in light assembly and packing machines.

Mass moment of inertia is the critical sizing criteria for rotary drives,
however it is difficult to estimate, which often can lead to risk of premature
failure. Over sizing also increases costs and wastes energy.
Engineers can also take advantage of Festo’s free software tools to make sure
they are sizing their actuator correctly to achieve best performance.

The new DRVS compliments Festo’s existing range of actuators including the
DRRD, which is an economical yet robust drive for higher load
applications.
