TOTAL NOOB, so sorry if this is obvious or poorly communicated
I purchased a 6in linear actuator for a project that probably needs 3-5 inches of travel. I thought I could just specify some percentage of travel. The listing for the actuator said "
Unit can be controlled with a double pole, double throw switch or with the built-in position sensor and optional linear actuator programmable controller"
The actuator showed up had only two wires going to it… I was expecting it to have 4 or 5 wires. Can an actuator with two wires know what position to go to? (does that make sense?)
As an add-on to my point, I found this:
instructables.com/id/Control … ith-an-An/
The actuator pictured looks just like the one I got, but again, mine only has two wires.
