1. An analyte measuring system, comprising:
- a mounting unit adapted for mounting on a skin of a host;
an electronics unit comprising contacts, wherein the electronics unit is detachably connectable to the mounting unit, wherein the electronics unit comprises electronic circuitry encapsulated within a substantially seamless body comprising the contacts exposed on an exterior of the substantially seamless body;
a sensor configured for measuring a level of an analyte, the sensor comprising an in vivo portion for insertion through the skin at an exit site of the host and an ex vivo portion connected to the contacts when the electronics unit is detachably connected to the mounting unit; and
an elastomeric sealing member configured to form a watertight seal around the exposed contacts on the exterior of the substantially seamless body and at electrical connection areas on the ex vivo portion of the sensor, wherein the elastomeric sealing member is connected to the mounting unit, wherein the elastomeric sealing member comprises at least one conductive elastomer contact disposed within the elastomeric sealing member.
