Miniature Linear Actuator

Hi,

If a pneumatic solution will work for you might check Clippard Minimatic.

(with a handle like Jonny5, my imagination is running WILD with possibilities as to the use of this miniature actuator).

Check out radio control servos. Price is reasonable.

They have the accuracy you need, you just need to send it the right signals, not too difficult.....servo testers are available to do just that for a few bucks....

Speak with Harry Hogg, Sales Manager, Helical Technology Ltd. on 44 1253 733122.

This Company will Design, develop and manufacture an Actuator to your specification. They are also Spring manufacturers, so they shoud be able to give you a good solution!

Did you take a look at the Smoovy?

It is pretty close to your specs.

If I remember well, these used to be in the $125 range in 10 quantity, in year 2001, before being taken over by Faulhaber. They used to be RMB, but when they sold off the motors, they changed to Myonic and still supply cool miniature hardware.

Alternatively you could use a small lead screw such as Kerk with a low cost motor and gear head of your choice.

If you can work to change some specs, these unusual actuators may fit your application:
