20/4 AWG Shielded Load Cell Cable with Nickel /Zinc wire sheath. This is NOT stainless steel so it may rust over time but the sheathing provides at least a measure of protection against rodents and animal damage. Remember that the maximum length that you can run your indicator cable is about 50' before you start to lose signal.
Can be wired direct to the junction box and scale indicator or you can add your own plug. Price is per foot.
