Good quality cable needed

[NickMu]

Some few years ago I ran across a specialized cable for RS485 data communication.
The cable was double shielded, heavy duty jacket, two power conductors and a separate twisted pair for data, not sure if it had one more layer of shield over that.
My Google searching did not get me any promising results so any information any one ca share in this matter will be greatly appreciated.

Please use the description above for the basic requirements for the type of cable I need.

This is probably of no help but have you considered a low baud rate in place of a deluxe cable?
I use standard (non Cat) telephone wire for example and at 300 baud (typing speed) it seems bulletproof.

Thank you Norm for your input.
My application requires a minimum 19.200 baud rate (I hope to get 38.400).
High noise environments and harsh humidity combined with sun exposure (ocean + Florida are the key words) are asking for highest quality cable I could get. It will be nice to keep the price as low as possible considering that I will be using quite large quantities but in this particular case the quality comes first.
I forgot to mention also that it has to be stranded wires with a gauge around 22 AWG.

Perhaps wireless would simplify the material setup requirements.
What distance is required?

See Belden 3109A or for listing.

Thank you again Norm.
The total cable length is about 150’.
Wireless is not an option due to the fact that the remote module (slave) will, at some point, be submerged and a 100 % reliable connection is a must.
The cable you suggested fits some of the requirements but I’m looking for only one twisted pair and two power wires. Heavy duty jacket and shielding are a must along with availability in large quantities with no lead time. I will be employing half duplex communication using a custom protocol.

I can not express enough how much I appreciate your help.

I might have to contact some of the major cable manufacturers for some help but I tried the forum first hopping that someone might already be using something like this and knowing that is nothing I can do until after the weekend.

Nick
