Description
Super Duty Linear Actuator – Rugged Performance, Quiet Operation, Optional Feedback
The Super Duty Linear Actuator is designed for high-load applications, combining a durable, heavy-duty build with quiet, smooth operation. It features a worm gear drive mechanism, making it much quieter and significantly harder to back drive compared to standard linear actuators.
Built from a thick aluminum housing with aluminum extension rods, this actuator is engineered to handle high forces in demanding environments. Integrated end-of-stroke limit switches automatically stop the actuator at its fully extended and retracted positions for safe, reliable operation.
Each unit comes equipped with a 4-wire Hall Effect Sensor for accurate positional feedback, ideal for synchronized or closed-loop control systems. However, if feedback is not needed, the actuator can be operated with just the standard 2 power wires, offering flexibility for both advanced and basic applications.
Available in two force/speed configurations and stroke lengths from 2" to 40", in 2-inch increments, the Super Duty Actuator delivers performance and adaptability for a wide range of uses.
We call it the "Super Duty" because it has it all: high strength, quiet operation, optional feedback, compact design, and customizable stroke lengths, perfect for your most demanding automation needs.
Features and Benefits
- ✔️ Works perfectly with Control board FCB-1 or FCB-2 for the ultimate in Actuator control
- ✔️ Rugged compact design for universal hardy applications. These units are smaller than other actuators for the same force output
- ✔️ Metal Alloy Casing, for any Super Duty usage, utilizing a completely sealed enclosure, ready to be deployed in any application.
- ✔️ Internal limit switches automatically shut off the unit at the end of the stroke - This protects you and your equipment from possible damage.
- ✔️ Worm gear drive system for quiet, smooth operation.
- ✔️ 2" stroke increment range of stroke options up to 40" stroke, gives you more flexibility.
- ✔️ Delivering force options from 220 to 450 lbs.
- ✔️ Optional Hall sensor feedback built-in. If you want to use it, ignore if you don't need it. 4 wires for the Feedback are included on all these models (black, white, and red). Controller FCB-1 or FCB-2 to give you full actuator control options, including speed adjustment, limit switch adjusting, and timer function
- ✔️ Actuator wiring is simple. 2x 18AWG wires (Brown & Blue) for the motor. Reversing polarity changes the direction of operation. 4x 20AWG wires (Red/Yellow/Black/White) for the sensor. (View any of the dimensional drawings for the wiring outputs)
- ✔️ IP66 rated – this offers dustproof and water-resistant
- ✔️ Variable Speed control - Use FCB-2 or FA-SC2 to have full control over speed - or Control board FCB-1
- ✔️ Maintenance-free - Gives you more free time to do more important things
- ✔️ Accessories sold separately include: Actuator Brackets - Remote Controls - Switches - Micro-Controllers - Power Supplies
- ✔️ For help with wiring up a Linear Actuator to other devices such as remotes, controllers, multiple Actuators, etc. please use our Wiring Generator
- ✔️ Brackets: MB17, MB20 & MB21
