16. An apparatus, comprising:
(a) a shaft assembly;
(b) an end effector positioned at a distal end of the shaft assembly, wherein the end effector is operable to engage tissue of a patient;
(c) a control module configured to generate a power output to power the end effector;
(d) a first electrical connector operatively coupled with the control module, wherein the first electrical connector includes a first plurality of electrical contacts, wherein at least one electrical contact of the first plurality of electrical contacts is configured to transfer the power output to a second plurality of electrical contacts of a second electrical connector while the first and second electrical connectors are coupled; and
(e) a plurality of nonconductive structures disposed adjacent each of the plurality of first electrical contacts, wherein the plurality of nonconductive structures are configured to prevent a signal interference between each electrical contact of the first plurality of electrical contacts, wherein at least a portion of the plurality of nonconductive structures is interposed between the first and second electrical connectors while the first and second electrical connectors are coupled, wherein at least one of the plurality of nonconductive structures includes a sensor configured to measure a signal or a power transferred through the first and second electrical connectors, wherein the sensor is interposed between the first and second electrical connectors while the first and second electrical connectors are coupled.
