Systems, methods, and devices are described for medical device subassemblies that include magnetic features. The system includes such catheter adapter subassemblies (1012, 112, 12, 212, 312, 512, 612, 712) or needle subassemblies (1112, 114, 14, 214, 314, 514, 614) or guidewire introducers Subassemblies (1216) and wires (1050) including magnetic features, can use magnetometers to determine catheter adapter subassemblies (1012, 112, 12, 212, 312, 512, 612, 712) or needle subassemblies (1112, 114) , 14, 214, 314, 514, 614) or the relative movement of the wire introducer subassembly (1216) and the wire (1050). |
