1. A modular surgical instrument system, comprising:
a handle assembly, comprising:
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 primary wired interface configured to transmit at least one of data and power between the control inner core and at least one of modular components of the modular surgical instrument system;
a secondary interface comprising a sensor located within the outer housing, the sensor being configured to detect a presence of the control inner core in the disposable outer housing; and
a control circuit configured to confirm a primary connection between the control inner core and the disposable outer housing through the primary wired interface based on at least one reading of the sensor.
