CHAPTER 12 ■ SOLDERLESS PROTOTYPINGObtaining Reinforced Jumper Wire
Reinforced jumper wire has sturdy metal posts on both ends covered in a rubber insulator. The rigidity and
size of the posts makes it very easy to insert and remove the wire from the holes. The height of the posts
extends over the top of components. The length of the wire allows for greater reach.
Common lengths for reinforced jumper wire are 50 mm (millimeter), 100 mm, and 200 mm. The
100 mm length is the most practical, although the shorter and longer lengths come in handy every once
in a while.
The rubber-covered posts are finger friendly. They fit snugly, yet no tools are needed to move them
around. Definitely stock your prototyping lab with lots of reinforced jumper wire (see Table 12-3).
