On a CNC machine it is worth considering the oil resistance of cables. Also, if mounted in a drag-chain you my need to use especially flexible cables. (I replaced the prox wires in my Chinese lathe for the second time this weekend, the standard cable that comes bonded into the cheap prox switches seems to have limited life when flexed).
On the Holbrook I am trying to make a somewhat higher-quality job of things, and that includes trying to source the right cabling. A useful source (in the UK) is Rapid Electronics who seem to have access to the inventory of Conrad Electronics, and who sell cables by the metre. This is useful, as these cables run to £100s or even £1000s per reel. For Smart Serial devices, and anything else using CAT5 cables these are probably ideal (the PUR sheathed variants) http://www.rapidonline.com/lappkabel-2170297-unitronic-ethernet-blue-data-cable-4x2x0-22mm-od-6-3mm-49-1788 (see the table at the bottom for variations) For cables in drag chains they have a special section: http://www.rapidonline.com/drag-chain-cable Of those this one is probably ideal for Modbus: http://www.rapidonline.com/lappkabel-unitronic-bus-pb-fd-p-violet-cable-555062 And this for resolver/encoder data: http://www.rapidonline.com/lappkabel-6fx8008-green-data-cable-555138 However, an even cheaper option for Modbus seems to be musician-rated cable. I have installed some of this and it works very well for my VFD. http://www.ebay.co.uk/itm/141838984494 -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." — George Fitch, Atlanta Constitution Newspaper, 1916 ------------------------------------------------------------------------------ Find and fix application performance issues faster with Applications Manager Applications Manager provides deep performance insights into multiple tiers of your business applications.
