Price listed is per meter. Apogee uses a custom formulation for our wire that has been selected for its rugged durability in all outdoor conditions. Our three-conductor cable is 26 AWG, tinned soft-annealed copper with an aluminum foil and drain wire to minimize electrical noise. The TPR jacket has excellent flexibility and water impermeability. Because we buy very large quantities, we are able to make this cable available to our customers at a very reasonable price. Price listed is per meter, and when used with the Apogee splice kit, your cable extensions are nearly as good as a length of original cable. This three-conductor cable is meant for use with our sensors having three leads (plus ground) or less. You may have an unused lead with some sensors. Please consult our wiring guide for more information.
