Linear Actuator control?

Hi guys,

Been a while since ive been here, sorry about that.

Anyway, Can anyone tell me if you can limit the stroke on a linear actuator??

I want to use one to control the headlamp covers on my 70 cougar instead of the vacuum set-up but dont really have any idea how to go about it. ie: controlling the actuator through the headlamp switch on/off and having the actuator move the correct amount.

Any advice
Cheers
Nick

McMaster-Carr carries those things and some of them might be just what you need..They come in several different varieties..Some of them I think have an adjustable travel range..would bear some more checking..

Some have limit switches, some don't ..You can also make your linkage adjustable and utilize the full stroke of whatever actuator you use.

Some places that sell smaller actuators are , Firgelli automotive, dakota digital, autoloc and IIRC even speedway sells them.

So where it says 'Limit switches, Non movable' does that mean it will only stop at the start and end of the stroke?

If thats the case I need one with 'Movable Limit switches' yes??

They are exactly as the name implies.

In which case the ones on the Hoffman group website seem perfect as you can adjust the stroke and as a plus they even show a wiring diagram!!!

Expensive but hey, custom work is I suppose

Many thanks for your time and help.
