Yes anything that gives some separation will work. The better cable chains like Igus can be bought with dividers that can be inserted.
With higher Power cables like from VFD I run bit of silicone tube between, often it's water pipes, but anything that can keep a bit of separation really.

I find those that have the most troubles with noise are the neat freaks that need everything tied and bound together with cable ties or tape.!!

Ric What voltage are you powering the Prox sensors with.? . . . . Running 24V on signal cables makes a big difference to noise handling has well.!! Often folks use 5V for Limits etc signal cables and get noise, esp if they haven't been too careful with ground or cable routing.!
