I have a carraige being operated by a transmission drive on a 120v 3ph 2hp motor. I am using a magnetic contactor, followed by a reversing drum switch (a later addition when they didn't want to push the cart back after each run). Now they want to add a switch down by the end of the tracks to break the circuit when the carraige passes a certain point (in case the operator isn't paying attention). How can I do this? I thought about wiring it via the coil power but the switch needs to be almost 80ft away, which in both directions will be 160ft and will require a very big wire size to avoid the voltage drop. I wish all of these things were addressed when they designed the system instead of adding all of this now. Any idea how I can do this?
