I am messing with a project that goes under ground - about 1 meter, and I want the controller box to be over ground.
There is 4 microswitches, a permanent magnet that needs 12V to release, and a stepper motor
The wiring plan so far is:
12V for magnet (not permanent)
Sw1 (Shortcuts to GND when pressed)
Sw2 (Shortcuts to GND when pressed)
Sw3 (Shortcuts to GND when pressed)
Sw4 (Shortcuts to GND when pressed)

I am looking for a generic cable solution that is:
[ol]possible to assemble yourself, or available in standard lengths
Possible to get a reasonable priced connector to mount on the PCB
Relatively sturdy and stable[/ol]
My first idea is a standard 2 row DB15 or 2 RJ45 cables…
Definitely 2 cables, a (smaller) one for the signals, the (bigger) one for the motor/magnet lines.
Both with shields, connected to ground.
For power cable, it might be important to use the correct wires.
What I mean is :
GND and 12V-Magnet on twisted pair of wires,
same with twisted pair of wires on “Motor 1A & 1B” and with “Motor 2A & 2B”
