REVISION

A change to a contact changes the tool.

Connector revisions reach further than most, because the contact is crimped with a tool set to a dimension, and the tool is part of the specification.

Why interchangeability is a separate column.

Because a revision can keep the same shell and change the contact. Two revisions then mate mechanically and differ electrically, and a harness built from both is neither revision.

The habit worth copying.

Recording the tool setting with the revision. Without it, the drawing describes a crimp that nobody can reproduce.
