Arduino Synchronous Control


When you need to know the exact positioning of your actuators, the Optical Feedback series is what you want. This powerful, reliable actuator comes with a built-in optical sensor that provides feedback when you need it.  The Optical Feedback has no built-in controller, but does provide single-phase pulses as a feedback signal that can be input to an external controller such as an Arduino

To move between 2 and 4 synchronized actuators, we recommend our dedicated control board, the FA-SYNC-X. A video tutorial on how to use this product is available here

CAD models of this actuator can be found under Resources/3D Files. For further information review the specifications and technical drawings down below or visit our tutorials page for instructions on how to use this actuator with switches, remotes, speed controllers, and Arduino. 

35 lbs. model not currently compatible with SYNC-X boxes.

Features and Benefits

  • 10 hole optical encoder disk for the 200lbs and 400lbs units
  • 4 slotted optical encoder disk for the 35lbs units
  • 20 pulse/inch of stroke for the 35lbs (+/-5 pulses)
  • 100 pulses/inch of stoke for the 200lbs and 400lbs units
  • Internal limit switches automatically shut off the unit at the end of the stroke - This protects you and your equipment from possible damage.
  • Huge range of stoke options as standard:  1, 2, 3, 4, 6, 9, 12, 18, 24, and 30 inches are available - Gives you more flexibility.
  • 3 Force options - 35lbs 200lbs and 400lbs for greater flexibility
  • IP66 rated – dustproof and water-resistant - Because it never hurts to have more protection than you actually need 
  • Maintenance-free - Gives you more free time to do more important things
  • Accessories sold separately include: Remote Controls - Switches - Micro-Controllers - Power Supplies
