Great video, area there any problems that you are aware of regarding installing them in a hot humid greenhouse for ridge and side vent opening? Thank you.

I bought an actuator for my boat trim motor and it lasted about 3 weeks before it died. I made sure it was water proof and then I also sprayed it with water proofing. So that is one thing you forget to mention. It had much more dynamic and static load rating than I needed and was the correct voltage. It was slow but I would rather slow than not enough lift. Anyway, I would be interested to know what went wrong. The company had a 30 day return but by the time I was able to install I really only got about 3 weeks out of it and maybe had to lift the motor 8 times during that period. Can you comment on what may have/could have gone wrong ?

Hi, thanks a lot for your interesting video; I just have a question if you permet Does the linear actuator contain a limit switch that stop it even if we're giving an order to the motor to move ( forward and backward) ? THANKS :)

Hi David, there are various ways you could go about it. For example you could use a limit switch ( www.servocity.com/electronics/components/switches/limit-switches ) that is physically engaged to turn on the light. Or you if you are using something like an Arduino or Raspberry Pi with a servo hat you could use a linear servo ( www.servocity.com/servos/linear-servos ) and a PWM switch ( www.servocity.com/electronics/components/switches/pwm-switches ) and send two PWM signals, one to control the linear servo and one to turn on the light via the PWM switch. You could also use a PWM switch with a Y-harness and linear servo to run them both off of the same PWM signal (like from an RC receiver or Arduino, Raspbery Pi etc) but the light would turn on the entire time the servo is extending and not just at full extension. Let us know if you have any other questions tech@servocity.com.

The battery was just a lawn mower battery so that the power source would be quickly recognizable by viewers. Any 12V source will be fine so long as it can provide enough current to operate your linear servo (more applicable when selecting the proper power supply that plugs into the wall). The capacity of the battery will depend on the desired run-time and the current draw from the linear servo will depend on the load and frequency of movement.

Hi George. Although either a linear servo or linear actuator could be made to do that, it would be more simple with a linear servo. An exact example would depend on how you want to go about controlling it. A no-programming option would be to use a servo recorder (part number SPC2000). Or you could use an Arduino and alternate between the servo.writeMicroseconds command and the delay command. Feel free to let us know should you have any additional questions tech@servocity.com.

Is there an easy way to get this to go one way with a single wire that powers on, then reverse when power to that wire goes off? I was trying to think of a way to include a dpdt relay and i think that's the idea but i can't think of how to flip the polarity using that single wire's power change.

Interestingly I made this ( circuits.io/circuits/2563498-dpdt-relay-to-toggle-polarity-via-on-off-switch ) recently to illustrate this very thing to someone. This of course would apply to the linear actuators not the linear servos. If you are using a microcomputer/microcontroller you will either want to find a DPDT relay which does not exceed the current rating of your pins (for example Arduinos are generally 40mA) or you could use a transistor to turn the DPDT relay on/off. Sort of like this ( www.instructables.com/id/Simple-Cheap-Motor-Controller/ ) only going to the relay instead of a motor and pulling it high/low instead of sending it a PWM signal.

You can certainly use linear actuators or linear servos in place of hydraulics if the speed, thrust, stroke length and overall size fit your model. Since we’re quantifying a linear force they are rated in pounds rather than a torque measurement. The amount of weight it can lift will depend on the placement of the actuator in your assembly. Prices vary based on what selection you make; we have HD linear servos which are the most plug-and-play solution for r/c. We offer HD linear actuators that are less expensive but more intensive to hook up to R/C (require a motor controller that can convert the PWM signal to a voltage that would get sent on to the motor). and SD linear actuators which are the same as the smaller ‘HD’ linear actuators but beefier for more industrial applications. The video covers how to connect a linear servo or linear actuator to a servo controller. An R/C transmitter and receiver is just a wireless servo controller so it’ll connect the same way.
