FRD Series

The new rotary limit switch Driver Series FRD – one of the latest creations by Ravioli as the result of extensive research based on the user experience – is an electromechanical device suitable for the accurate and safe control of construction equipment and industrial machines.

Once the limit switch FRD is connected through its shaft to a gear motor or a rotary winch, and a specific number of turns is pre-set, the adjustable cams trigger the internal safety contacts with high precision.

Contacts are positive-opening, and an absolute angular rotation sensor can be fitted to allow linear position control.

Several designed accessories are available to facilitate the coupling between the machine and the limit switch.
