For an Industrial Solution, I have to use 8 Core cable more than 200 terminals to my device for maximum length of 4 to 8 meters. this for push button signal and switch indicators from micro control circuit board. I am planning to use Ethernet CAT5 shielded cable for this purpose. (shielded cable planning because it laying near heavy electrical motor and EMI/EMC noisy area) Any experts experienced this kind of solution or any body expecting any kind of issues in this approach?
Use cat5e with shielding FTP / SFTP for good EMI protection.
Cables are available also in kevlar, PVC, ... jackets in combination with IP protection ( https://en.m.wikipedia.org/wiki/IP_Code ).
