limited use

I am into model railroading and this linear servo is perfect for switching track turnouts, that need minimal torque to operate!

great little servo, get what you pay for

This little servo is so easy to implement and works pretty well. The pager motor that runs it can sometimes get dislodged from the gear system which makes it stop working, but you can open up the box and push it back into place (and add a bit of glue/epoxy to get it to stay in place).

ok, but not great

absolute maximum force ~1.5N@3,6V. expected a bit more.

Good price / quality

Probably the smallest linear servo you can get on the market. Opens horizons for new miniature applications. The torque is not great - should not exceed 140-160 g load. All gears inside are plastic so consider not to use it in heavy duty applications. Because of the backlash of the central nut and the printed resistive tracks of the potentiometer (directly on control PCB) it can't be used for very precise positioning but is excellent for discrete states (like open or close a vent, etc.). The pure move is not 20mm as stated but 17mm, it takes 1s to move from one end to the other on 3.6V. Because of the plastic gears and the coreless motor the noise when moving is low. I would recommend you get some samples to play with, for sure you'll get new ideas where to use it.

simple to use

Can operate it via Matlab without any trouble. Moves precise enough for my application, but the reliable travel in my case is 1.5cm, not 2. My project uses four of these, and not all move to the same position when you put them at the same pulsewidth. Requires a bit of callibration.
