A connector ring comprising a body extending along a longitudinal axis and two sets of sensor connectors. The first set of sensor connectors comprises one or more transmitter sensor connectors coupled with the body and extending parallel to the longitudinal axis, the one or more transmitter sensor connectors having a first end. The second set of sensor connectors comprises one or more receiver sensor connectors coupled with the body and extending parallel to the longitudinal axis, the one or more receiver sensor connectors having a first end. The first end of the transmitter sensor connectors and the first end of the receiver sensor connectors are staggered along the longitudinal axis.
