The base plate comprising: a top layer; an electrode assembly; and a monitor interface configured for connecting the base plate to a monitor device. An axial distance along an axial direction between a proximal facing edge of a coupling part and a contact surface on the distal side of the top layer is a first axial distance. The first axial distance being less than a second axial distance between a distal facing edge of the monitor device and a proximal facing side of the monitor device, such that upon connecting the base plate to the monitor device the proximal facing side of the monitor device contacts the contact surface to force a first connection parts to contact a first terminal element. ## Claims ### Claim 1 An ostomy appliance having an electrical connector, the ostomy appliance comprising: an adhesive layer on a proximal side of the ostomy appliance, the adhesive layer adapted to secure the ostomy appliance to skin of a user; a top layer on a distal side of the ostomy appliance; an electrode assembly disposed between the adhesive layer and the top layer, with the electrode assembly comprising a first electrode; a connector attached to the top layer, the connector adapted to provide electrical connection between a detachable data monitor and the electrode assembly, the connector comprising: a coupling element projecting axially away from the top layer in a distal direction with a proximal facing edge projecting in a radial direction away from the coupling element, and a first terminal element comprising a proximal part connected to the first electrode and a distal part connected to the coupling element: wherein, when the detachable data monitor is mechanically coupled with the connector, the proximal facing edge of the coupling element presses the first terminal element axially to e electrical contact with the first electrode. ### Claim 2 (depends on 1) The ostomy appliance of claim 1, wherein the connector further comprises a protrusion formed distal to the top layer, with the protrusion adapted to mechanically coupled with the detachable data monitor. ### Claim 3 (depends on 1) The ostomy appliance of claim 1, wherein the coupling element provides a pocket sized to receive a portion of the detachable data monitor and the first terminal element is located within the pocket of the coupling element. ### Claim 4 (depends on 1) The ostomy appliance of claim 1, wherein the terminal element further comprises a central portion; wherein the proximal part of the first terminal element is disposed between the adhesive layer and the top layer, the distal part of the first terminal element is distal to the top layer, and the central portion of the terminal element projects through the top layer. ### Claim 5 (depends on 1) The ostomy appliance of claim 1, wherein the electrode assembly comprises a plurality of electrodes including the first electrode and a second electrode and further comprises: a second terminal element connected to and extending between the second electrode and the coupling element. ### Claim 6 (depends on 1) The ostomy appliance of claim 1, wherein the connector further comprises a coupling flange attached to the top layer of the ostomy appliance, wherein the coupling element is integrated with the coupling flange. ### Claim 7 (depends on 1) The ostomy appliance of claim 1, wherein the electrode assembly further comprises a support layer, with the electrode assembly disposed on a proximal side of the support layer. ### Claim 8 (depends on 1) The ostomy appliance of claim 1, further comprising an intermediate adhesive layer disposed between the electrode assembly and the top layer. ### Claim 9 (depends on 1) The ostomy appliance of claim 1, further comprising: a support layer disposed on a distal side of the electrode assembly; and an intermediate adhesive layer disposed between the support layer and the top layer; wherein the first terminal element connects between the first electrode and the coupling element of the connector. ### Claim 10 (depends on 1) The ostomy appliance of claim 1, wherein the electrode assembly and the connector combine to provide a sensor assembly adapted to sense and determine moisture propagation in the adhesive layer. ### Claim 11 (depends on 1) The ostomy appliance of claim 1, wherein the electrode assembly and the connector combine to provide a sensor assembly adapted to communicate data to the detachable data monitor related to a time for replacement of the ostomy appliance prior to stoma-output leakage relative to the adhesive layer.
