VS-19 Pico Linear Servo

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

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).

Motor works fine. Datasheet tells nothing you need to know: I experienced that using the indicated voltage to the motor makes it working with hick-ups; applying 5V makes it move ok. Set your uC pwm timer to 400 Hz; duty cycle at 88% makes it move one way, dc at 60% is in the middle, dc at 32% makes it move the other way. Put the output pins to gnd when done moving.

This servo easily receives 5 stars. It is small powerful and built strong. Great product!!

I like the size of the linear servo, it can be installed in a thin space. The travel of the servo can be adjusted very easely.
