An electrically conductive 5 material having a measurable strength measurable by a hall effect sensor (35) is coupled to the component (254). In another embodiment, a plurality of conductive materials are arranged to form a binary code representing a corresponding of the interchangeable component (254). The number and/or strength of the magnets (30) measurable by the sensors (35) may be dynamically altered such that the status of the surgical instrument is io determinable.2/7 2 28 b 5 S28a 65 18c 18. 3 12 40 503638 52 I 8b 50 35 48 58 FIG. 2
