1. A sensor apparatus for a continuous glucose monitoring system, the sensor apparatus comprising:
a sensor housing including:
a first end having a sealing surface configured to seal against an introducer;
a second end having a sealing surface configured to seal against an insertion shaft cover;
an insertion shaft opening that extends between the first end and the second end and having a width that allows an insertion shaft of the introducer to travel through the insertion shaft opening, the insertion shaft opening defined by an inner surface of the sensor housing;
an outer surface having a sensor wire contact location; and
a sensor wire channel that extends between the insertion shaft opening of the sensor housing and the sensor wire contact location;
wherein the sensor wire channel and the sensor wire contact location are each configured to receive a corresponding section of a sensor that extends between the insertion shaft opening of the sensor housing and the sensor wire contact location, such that a first portion of the sensor is sealed within the insertion shaft opening and a second portion of the sensor is disposed at the sensor wire contact location, and further configured to allow the second portion of the sensor to contact one or more of a plurality of vertical contact elements disposed within a sensor housing support of a bottom case,
wherein the plurality of vertical contact elements are electrically coupled to an electrical circuitry of the continuous glucose monitoring system prior to contacting the sensor,
wherein contact of the second portion of the sensor with one or more of the plurality of vertical contact elements makes electrical contact of the sensor to the electrical circuitry, the contact occurring externally to the sensor housing.
