Powered surgical instruments with smart reload with separately attachable exteriorly mounted wiring connections

A modular surgical instrument system, comprising:

• modular components characterized by unique identifier resistances, the modular components comprising:
• a shaft;
• a handle assembly releasably couplable to the shaft, wherein the handle assembly comprises:
• a disposable outer housing configured to define a sterile barrier, the disposable outer housing comprising:
• a first housing-portion;
• and
• a second housing-portion movable relative to the first housing-portion between an open configuration and a closed configuration;
• and
• a control inner core receivable inside the disposable outer housing in the open configuration, wherein the disposable outer housing is configured to isolate the control inner core in the closed configuration;
• a loading unit releasably couplable to the shaft, wherein the loading unit comprises an end effector;
• and
• a staple cartridge releasably couplable to the end effector;
• and
• a control circuit electrically couplable to the modular components, the control circuit configured to:
• detect a modular configuration of the modular surgical instrument system based on the unique identifier resistances;
• and
• assess authenticity of the modular configuration.
