## Abstract

The application is directed to various connector and sensor assemblies are described. The connector can have an opening that has a first surface and second surface that are opposite each other. The connector can include a plurality of retractable electrical connectors that extend from the first surface and a lock structure that is located on the second surface. The sensor assembly can include a body portion and a proximal end. The proximal end has a top side and a bottom side. The top side includes a plurality of electrical contacts that is configured to interact with the plurality of retractable electrical connectors. The bottom side includes a key structure that is configured to interact with the lock structure in the connector.
