Hi,
building a tool where we like to position two encoders. all this is going inside a pipe that is 15.meters, so we are looking at approx 16.meter cable from actuator out to the control box.
will it work or is it to long. thinking of interference etc.

Hi @stein_M and welcome to our forum!
Which cable are you using?
Is it only for powering the actuators (like red and black wire) or there is also communication protocol transmitted via this cable ( encoder cable, RS-232, or similar)?
Hi @igor_X, thx.
to be honest I’m not sure yet. we like to keep it simple so i think we are talking of power and maybe some end switches if we need. when it comes to type of cable I’m totally green, mere of a mechanical engineer that ended up whit this
problem so all help i most welcome 
Hi @stein_M !
If it is just wiring for power, then you can calculate voltage drop on that length. You can calculate which voltage level you gonna need on power supply and.
Basically, voltage drop is smaller if wire is thicker. Also it is small if wire is shorter.
Thx @igor_X.
I hope and think it will be ok. if the wire is the right thickness. was mostly afraid of interference if we need some kind of signal to drive the actuators. I guess the limit switches is only “power” that are broken when switch is engaged.
If your actuators have only limit switches then yes, it is just power cables.
