Hook-up Wire Spool Set - 22AWG Stranded-Core - 6 x 25ft ADA_Security The sensor comes with threeThis is a box of six 25ft spools of stranded core wire. Stranded core wire is best used for wiring jigs where there's bending or movement expected. It also works well with terminal blocks. It's not great for use with breadboards (without tinning). The wire is easy to solder to, and when bent it keeps its shape pretty well. We like to have a few spools of this stuff around which is why this set is quite nice! We suggest picking up some wire strippers
